In home appliances (air conditioners, refrigerators, washing machines, discharge lamp lighting devices, etc.), etc., a program execution device is incorporated in order to control the operation (hereinafter, such appliances, home appliance adapters, etc. are incorporated). Called). Here, in order for the program execution apparatus to execute the execution process, data called a predetermined program code is required. This program code is stored in advance in a storage means such as a ROM (Read Only Memory) provided in the embedded device, for example, and the program execution device reads (inputs) the program code stored in the ROM and executes it Processing is in progress. An apparatus for supporting generation of such a program code has also been proposed (see, for example, Patent Document 1).
JP-A-9-16382

  Here, the environment in which the program code is used is not necessarily uniform. For example, it varies greatly depending on the embedded device (particularly, the program execution device). Therefore, it is desirable to generate the program code according to the characteristics of the embedded device. In particular, if the amount of data related to the program code can be reduced, the storage capacity of the ROM for temporarily storing the ROM or the execution process when the execution processing is performed in the program execution device can be reduced accordingly. In the future, it is also convenient when embedded devices are connected to each other via a network and, for example, signals including program codes are transmitted and received. However, the above-described support device simply generates a program code.

  Accordingly, an object of the present invention is to realize a program code generation support apparatus, method, and the like that can generate a new program code by further optimizing the program code, and in particular can perform generation according to an embedded device.

  A program code generation support apparatus according to the present invention includes a storage unit that stores, as data, a conversion condition for converting program code data and conversion contents, a code analysis unit that analyzes the program code, Based on the analyzed program code, it matches with the optimization rules stored in the storage means, and searches for a portion that matches the conversion condition in the program code, and a portion that matches the conversion condition based on the conversion content And a code optimizing unit having an optimizing unit for generating new program code data.

  According to the present invention, the code optimization means further analyzes the program code by the code analysis unit, and the condition search unit searches whether there is a part matching the condition based on the optimization rule. In addition, since the optimization unit performs conversion for optimization and generates new execution code (program code), it is optimal for the program execution device of the embedded device to easily execute execution processing. Can be In particular, by creating a new execution code by combining the portions of execution code based on the same command, the data amount of the entire program code is reduced, and the execution process can be performed all at once, so the processing speed Can be faster.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a system centering on a program code generation support apparatus according to Embodiment 1 of the present invention. The program generation support apparatus includes a specification input unit 1, a code generation unit 2, a code evaluation unit 3, a code optimization unit 4, an output unit 5, a storage unit 10, a display unit 20, and an input unit 30.

  FIG. 2 is a diagram illustrating an example of a screen displayed on the display unit 20 by the specification input unit 1. The specification input means 1 displays a screen for allowing the operator to input specifications on the display means 20, for example, and processes data input from the input means 30 as specifications. The processed data becomes the processing data constituting the execution code. Here, ECHONET (Energy Conservation and Homecare Network: ECHONET is a trademark of ECHONET Consortium) is a network (communication line) standard for controlling home appliances in cooperation with each other as shown in FIG. In this embodiment, it is assumed that a program code for executing an execution process in a device, an adapter, or the like connected according to the standard is generated. The relationship between each specification element (item) and processing data will be described later.

  FIG. 3 is a diagram illustrating an example of an execution code. The code generation unit 2 generates a program code based on the data processed by the specification input unit 1. In FIG. 3, it is described as text data. The program code is composed of one or a plurality of execution codes. The execution code is, for example, a unit when execution processing is sequentially performed by an interpreter in a program execution device included in an embedded device. In the present embodiment, Forth is used as the language used for the program code. Forth is a language based on reverse Polish notation that is easy or unnecessary to parse. In the present embodiment, the execution code includes command (instruction) data (hereinafter referred to as a command, word in Forth) representing processing to be executed by the program execution device, and data for processing based on the command (hereinafter referred to as processing). Data) and is described in the order of processing data and command. Here, each command and the data of its processing contents are registered in advance (associated) (this is called a dictionary). For this reason, data such as a character string described in the execution code is a command if it is registered in the dictionary, and is processed data if it is not registered. Further, it is assumed that the command is not limited to a predetermined one but can be registered as a dictionary by further defining the processing contents of the command. In this embodiment, this dictionary is stored in the storage unit 10 as the dictionary unit 10A. Here, the program code is generated using Forth, but the program code to which the present invention can be applied is not limited to this.

  Here, the code generation unit 2 generates a program code for evaluation so that the operator can easily evaluate the program code displayed on the display unit 20 in the processing by the code evaluation support unit 3 in the subsequent stage. For example, it is generated so that the character string of the execution code does not become too long, or is generated using a basic command that is not uniquely defined, so that it can be easily traced.

  The command RGST_EPC is described to execute registration processing of property information of the embedded device. The object id (obj_id) is an id assigned to the object of the embedded device. The ECHONET property (epc) is a code of a property that can be set according to the embedded device (for example, the air volume setting state in the air conditioner). The code value is defined by the ECHONET standard. In addition, seven types of property data types (type) are prepared (automatically determined when the embedded device and the property are determined). The access rule (rule) indicates whether writing, reading, and notification are possible. Status change announcement presence / absence (anno) is an indicator (flag) indicating whether or not notification is made via the network when the property state changes. The data size (size) is for defining the data size of the property, and the maximum value is 8640 bytes in the ECHONET standard.

  The code evaluation means 3 provides support for the operator to evaluate the program code (execution code) generated by the code generation means 2 or other means. For example, the program code is displayed on the screen of the display means 20 in order to evaluate the program code such as confirmation and debugging of the generated program code. Further, the program execution apparatus has an interpreter used when executing the execution process, and can execute the generated execution code. Thereby, the operator can confirm the execution process performed based on the program code (execution code).

  The code optimizing unit 4 optimizes the program code based on the optimization rule stored in the optimization rule storage unit 10B of the storage unit 10. The code optimization unit 4 includes a code analysis unit 4A, a condition search unit 4B, and an optimization unit 4C. An optimization rule is a data conversion rule that enables a program execution device to efficiently execute an execution process based on a program code, for example, by combining a plurality of execution codes and generating a new execution code. is there. The optimization rules will be further described later.

  The code analysis unit 4A analyzes the input program code. Here, the code analysis unit 4A has a counter, and counts the number of consecutive times for a portion having the same command and the execution code for executing the same content being continuous. The condition search unit 4B performs a search based on the conversion condition. That is, the analyzed program code is compared with the conversion conditions constituting the optimization rule, and it is determined whether there is a part that matches the conversion conditions. At that time, the count of the code analysis unit 4A is referred to. The optimization unit 4C performs conversion for optimization on the portion that the condition search unit 4B determines to meet the conversion condition, and generates a new execution code (and program code).

  Here, the code analysis unit 4A, the condition search unit 4B, and the optimization unit 4C may be configured as physically independent means, but here, for example, a control processing device centered on a CPU is provided as each means. By executing the above process, the process of each unit is realized. Note that the same applies to the relationship between the specification input unit 1, the code generation unit 2, the code evaluation unit 3, the code optimization unit 4, and the output unit 5, and each unit may be independent, but in this embodiment, It is assumed that the processing of the program code generation support device is realized by the control processing device executing the processing of each means.

  The output means 5 performs processing for converting the program code into data in a format suitable for the corresponding output device and outputting the data to the output device. For example, when the output device is the printing apparatus 40, a program code is added to data that is to be printed on the printing apparatus as a barcode, a QR code (two-dimensional barcode: QR code is a registered trademark of Denso Wave Inc.), or the like. A process of converting and printing on the print medium is performed. For this reason, for example, an expensive communication device dedicated to an embedded device is provided, and it is possible to directly connect to a communication line and transmit a signal without using a camera, an infrared communication technology, etc. that a mobile phone has, A signal including data can be transmitted to the embedded device, and the program code can be stored. As a result, the program code stored in the embedded device can be kept up-to-date even when a low-priced medium such as a paper medium is used. In addition, for example, the memory reading device 50 may be used as an output device to exchange data using an electronic storage medium. The communication device may be an output device. In addition to the dictionary stored in the dictionary unit 10A and the optimization rules stored in the optimization rule storage unit 10B, the storage unit 10 includes data for each unit to display on the display unit 20 on the screen, etc. A program or the like for supporting program code generation is stored.

  FIG. 4 is a diagram illustrating an example of the optimization rule. For example, as shown in FIG. 4A, if a program code is written so that “command RGST_EPC (ECHONET property registration is the processing content) is executed multiple times in succession, a plurality of ECHONET The rule “replace property registration with the command RGST_EPCS having the processing contents to be executed at once” is stored as an optimization rule in the optimization rule storage unit 10B. FIG. 4B shows the contents as script (description) data. The direction before the arrow indicates the conversion condition when the condition search unit 4B searches, and the point of the arrow indicates the conversion content when the optimization unit 4C converts (here, since it is continuous a plurality of times, n is 2). The code analysis unit 4A counts n). In the execution code related to the command RGST_EPCS, the processing data is the object ID (obj_id), ECHONET property (epc), data type (type), status change announcement (anno), and data size (size) for the ECHONET property to be registered. The pairs are arranged as many times as registration is repeated, and the number of repetitions is added. This command RGST_EPCS is also registered in the dictionary unit 10A. In this way, the execution code is combined into another execution code, and the data amount of the program code is reduced for optimization. Since a plurality of execution codes are executed together, the processing speed can be increased.

  FIG. 5 is a diagram illustrating another example of the optimization rule. For example, in FIG. 5, a rule that “sequential substitutions for different elements of the same array are replaced with a command SET_C_ARRAY that can assign values collectively” is stored as an optimization rule in the optimization rule storage unit 10B. FIG. 5B shows the contents as script (description) format data. Here, char represents a value to be assigned, c-addr represents an assignment destination address, and offset represents an offset from the head address. [] Attached to c-addr of the conversion condition when the condition search unit 4B searches and the conversion content when the optimization unit 4C performs conversion indicates that the content (character string) of the c-addr is the same. ing. Further, n is set to 2 or more, and the code analysis unit 4A counts it. For example, “1 BUF 0 + C!” Performs an execution process in which 1 is assigned to the 0th byte from the address BUF. In the execution code related to the command SET_C_ARRAY, the processing data is the value to be assigned (char) arranged n (for the number of repetitions), “BUF” indicating the address, n for the offset, and the number of repetitions attached. The command SET_C_ARRAY is also registered in the dictionary unit 10A.

  As described above, according to the first embodiment, the code optimization unit 4 further analyzes the program code generated by the code generation unit 2 in the code analysis unit 4A, and the condition search unit 4B stores the optimization rule. Based on the optimization rule stored in the unit 10B, a search is made as to whether or not there is a part that matches the conversion condition, and the optimization unit 4C determines that the condition search unit 4B matches the conversion condition. Since the part is converted for optimization and new execution code (program code) is further generated, the program execution device of the embedded device should be optimized so that it can be easily executed. Can do. In particular, by creating a new execution code by combining the portions of execution code based on the same command, the data amount of the entire program code is reduced, and the execution process can be performed all at once, so the processing speed Can be faster. At that time, the program code related to the generation of the code generation means 2 is generated in a form that is easy for the operator to evaluate when the code evaluation support means 3 displays the program code on the display means 20, It is possible to make it easier for an operator to perform confirmation, correction, and the like. Furthermore, since the output means 5 converts the program code into data in a format suitable for the output device, the program code can be recorded corresponding to various output device formats. In particular, if barcodes, QR codes, etc. are converted into data for printing and can be printed, the program code can be recorded on a low-cost medium. A general-purpose communication means such as a mobile phone can be used for signal transmission including the program code to the embedded device.

Embodiment 2. FIG.
FIG. 6 shows a program code generation support apparatus according to Embodiment 2 of the present invention. The environment for storing (storing) the program code in the embedded device and the environment in which the program execution device included in the embedded device performs an execution process based on the program code differ depending on the type of the device. In particular, when generating program code, the storage capacity of a ROM for storing (storing) the program code and the usable storage capacity of a RAM (Random Access Memory) during execution processing are important. Therefore, in the present embodiment, the conditions (execution processing environment based on the program code) of the embedded device are set and reflected when the program code is generated. In FIG. 6, the same reference numerals as those of the program code generation support apparatus of FIG. 1 perform the same processing operations as the means described in the first embodiment, and thus the description thereof is omitted.

  FIG. 7 is a diagram illustrating an example of a screen displayed on the display unit 20 by the embedded device condition input unit 6. The embedded device condition input means 6 displays on the display means 20 a screen for allowing the operator to input characteristics, conditions, etc. of the embedded device, for example, sets the instruction signal input from the input means 30, and performs code optimization. Transmit to means 4 and output means 5. In FIG. 7, the storage capacity (code storage capacity) of the ROM for storing the program code, the usable storage capacity of the RAM (usable RAM capacity), and whether or not to compress the program code (binary compression) , Whether to output the program code as a printing medium or to an electronic storage medium such as a memory card (output medium) and a QR code when the printing medium is selected (QR code is a registered trademark of DENSO WAVE INCORPORATED) Whether or not to convert to (conversion to QR code) can be set.

  The code optimizing means 4-1 according to the present embodiment performs optimization based on the storage capacity of the ROM and RAM of the embedded device input by the embedded device condition input means 6 in addition to the processing of the optimization unit 4C. It differs from the optimization means 4 in that the unit 4D is provided instead of the optimization unit 4C. Another difference is that a processing data / command identification unit 4E and a conversion unit 4F for compressing the program code are provided. In this embodiment, the processing data / command identification unit 4E and the conversion unit 4F are configured as a part of the function of the code optimization unit 4-1, but may be independent program code compression processing units.

  The optimization unit 4D generates a new execution code by performing conversion for optimization on the part that the condition search unit 4B determines to meet the conversion condition. At this time, the execution code to be collected is If the number increases, the data amount of the processing data increases, and the data amount of the new executable code may increase. Therefore, depending on the embedded device, when the program execution device performs the execution process, the storage capacity of the RAM that temporarily stores the execution code or the like may be exceeded. Therefore, if the optimization unit 4D determines that the capacity exceeds the capacity based on the data of the usable RAM capacity input via the embedded device condition input means 6, the data amount of each execution code is less than the capacity. It is generated by dividing it into multiple executable codes. In addition, when the data amount of the entire program code exceeds the storage capacity of the ROM for storing the program code of the embedded device, the processing data / command identification unit 4E and the conversion unit 4F are notified regardless of the setting. Perform compression processing. The above determination and the like are performed, and a new program code is generated.

  FIG. 8 shows compressed execution data. Next, the compression process will be described based on the execution code shown in FIG. When compression processing is performed based on binary compression input by the embedded device condition input means 6 and determination by the optimization unit 4D, the data / command identification unit 4E stores each execution code of the program code in the dictionary unit 10A. The processing data and the command are discriminated by collating with the stored dictionary, using the character string, number, etc. that do not match the dictionary as the processing data, and using the matched character string (script) as the command.

  The conversion unit 4F represents the processing data and the command as binary data. Here, 2 bits are used to represent the object id, 8 bits are used for the ECHONET property (epc), 3 bits are used for the property data type, 3 bits are used for the access rule, 1 bit is used for the status announcement, and the data size is 14 bits. assign. After being expressed as binary data, data divided for each predetermined data amount is generated. In this embodiment, 7 bits are set as a predetermined data amount. For example, when the processing data has a data amount that is not divisible by 7, for example, “0” is supplemented to the remaining bits. For data representing processing data (hereinafter, this data is also referred to as processing data), “0” is added to each of the divided head bits, and data for determining a command (hereinafter, this data is also referred to as a command). "1" is attached to the above. That is, this is a determination bit (flag) for determining whether it is processing data or a command. Thereby, each execution code (program code) is divided into each byte code in units of 1 byte (8 bits). As described above, the processing data divided into the character strings of the respective items (elements) are collectively processed as binary data to reduce the data amount.

  On the other hand, a command is represented by binary data corresponding to the command on a one-to-one basis. Thereby, the command represented by the binary data can be determined. The relationship between the command and binary data is associated and stored in the storage means 10 as data, and the conversion unit 4F refers to the data at the time of generation. Here, if the number of commands is 128 or less, one byte is sufficient to determine the command. For example, when the number of commands is more than 2 bytes, it will be 2 bytes or more. Even in that case, commands that are frequently used (appears) for execution processing (eg property-related) are also identified by 1-byte code data. By making it possible, the data amount of the entire program code can be further reduced. The byte-unit code data generated by the method according to the present embodiment may be further compressed by a known bit string compression method such as a run length method.

  Further, based on the data of the output medium input via the built-in device condition input means 6, the output means 5 determines the format for conversion and performs the conversion. At this time, when an electronic storage medium is selected as the output medium, “not” is automatically selected for conversion to a QR code. When a print medium is selected as the output medium, “Yes” is selected for conversion to a QR code.

  In the program execution device included in the embedded device, for example, ROM program code is stored via a storage medium or the like. The program code is read in 1-byte units, and it is determined whether the data includes a command or processing data based on the determination bit. If the data includes processing data, the program code is temporarily stored in the RAM. I will remember it. If it is determined that the data includes a command, it is expanded into an execution code and an execution process is performed.

  As described above, according to the second embodiment, the built-in device condition input means for setting the program code execution processing environment (ROM, RAM storage capacity, etc.) of the built-in device (the program execution device included in the built-in device). 6 and the optimization unit 4D generates a new program code based on the setting, so that it is possible to generate a fine program code according to the characteristics, conditions, etc. of the embedded device. Since the processing data / command identification unit 4E and the conversion unit 4F are provided and the program code can be compressed, the storage capacity of the ROM can be reduced, and the cost can be reduced. Then, in the compression processing, the processing data and command of each execution code are identified, the processing data is combined with each element (item) to be binary data, the command is the corresponding numerical value as binary data, and each data is 7 bits. Since the data is divided into 1-byte data by adding a determination bit for determining whether the data includes processing data or data including a command to each data, the processing data and the command can be compressed respectively.
