Referring to fig. 1, in the present embodiment, a master-slave system includes a master and at least one slave, and the master has a complete software and hardware system, which means: the host includes a core module and a peripheral module, the core module including at least: a microprocessor and a memory, the peripheral module comprising: IO cells, such as: a display, an ethernet, a wireless communication interface, a sensor, etc., and the slave does not include a peripheral module. Through the special hardware architecture, the slave computer does not need a peripheral module, and the cost is greatly saved.
In the present embodiment, one master 101 and one slave 102 are used for explanation, but in other embodiments, one master 101 and a plurality of slaves 102 may be used, and the operation principle is similar to that of one master 101 and one slave 102. In this embodiment, the host 101 is preferably externally connected to the slave 102 through an expansion slot, which may be included in the host 101 or may be external. In the present embodiment, an embodiment of the master-slave system 100 is as follows:
a master-slave system 100 comprising a master 101 and at least one slave 102, said master 101 comprising: an operating system layer 1011, a device driver layer 1012, a Demuxer layer 1013, or a Host layer 1014; the slave 102 includes: an operating system layer 1021, a device driver layer 1022, or a driver Client layer 1023; the host 101 accesses the peripheral IO cells through the device driver layer 1012 and the driver Demuxer layer 1013; the slave 102 accesses the peripheral IO unit of the host 101 through the device driver layer 1022 and the driver Client layer 1023; the drive Host layer 1014 is used to: data processing, command processing, protocol conversion or data transmission exchange; the driver Client layer 1023 is used to: data processing, command processing, protocol conversion, or data transfer exchange.
Further, the driving Client layer 1023 of the slave 102 interacts data through the driving Host layer 1014 of the master; the Host driver Host layer 1014 in turn accesses the peripheral IO cells by driving the Demuxer layer 1013.
Further, the host drives Demuxer layer 1013 to access the peripheral IO cells via device driver layer 1012.
The following are specific examples:
example 1 (how operations on slave 102 are synchronized to master 101):
the slave 102 operating system triggers display updating, the slave 102 processes the display updating corresponding to the display driver, the display updating command and data are transmitted to the slave 102 driver Client layer 1023, the slave 102 driver Client layer 1023 receives the data and processes the display updating according to the updating command and the data;
in this embodiment, the slave 102 driving the Client layer 1023 preferably transmits the display update related data and commands to the Host layer 1014 of the Host 102 via PCIE/USB. The Host 101 drives the Host layer 1014 to distribute the display update related data and commands to the demuxer of the sub-screen (VGA, etc.) or to the demuxer of the HDMI-OUT after receiving the related data and commands, and the following two cases are respectively explained:
if the data and commands related to the display update are distributed to the Deumxer of the sub-screen (VGA, etc.), the sub-screen driver responds to the display update, and finally the corresponding display update is performed on the physical sub-screen of the host 101.
If the data and commands related to the display update are distributed to the Deumxer of the HDMI-OUT, the HDMI-OUT drives to respond to the display update, then the HDMI-IN drives to respond to the display update correspondingly, the virtual Shell responds to the display update, and finally the main screen of the host 101 correspondingly displays the update.
Embodiment 2 Slave 102 uses the peripheral IO devices of the Master 101 (how Master 101 operates synchronized to Slave 102)
The Host 101 drives the Demuxer layer 1013 to receive input instructions of the peripheral IO units and send the input instructions to the Host 101 to drive the Host layer 1014; the Host 101 drives the Host layer 1014 to transmit the input command to the slave 102 to drive the Client layer 1023; the slave 102 drives the Client layer 1023 to send the input command to the corresponding drive layer of the slave 102; the slave 102 corresponding to the driving layer executes corresponding operation according to the input instruction.
Example 3 (extended Multi-core Performance)
The slave 102 operating system starts; the slave 102 calls a CPU registration driver; the slave machine 102 drives the Client layer 1023 to call a CPU registration driver; the slave 102 drives the Client layer 1023 to send related data and commands to the Host 101 to drive the Host layer 1014; the Host 101 drives the Host layer 1014 to respond to CPU registration according to the related data and commands; the host 101 responds to the CPU registration correspondingly; updating the CPU pool by the host 101 adds the CPU of the slave 102 to the CPU pool of the host 101.
By using the operating system, it is possible to realize dual-display dual display in which the slave 102 displays updates (i.e., the physical sub-screen display update mentioned in the above embodiment 1, and the main screen of the host 101 also displays updates), and also it is possible to realize dual-display single display, that is: only one of the two displays updates.
Through the system architecture, after the master machine and the slave machine are interconnected, the host machine 101 can manage and schedule a microprocessor (CPU) of the slave machine 102 through the multi-core management system, if the CPUs of the master machine and the slave machine are all 4 cores, after the expansion, the CPU which can be scheduled by the host machine 101 is 8 cores, and the multi-core performance of the host machine 101 is indirectly expanded.
Similarly, with this system architecture, the slave 102 does not have a hardware peripheral device, but can have a virtual peripheral system through virtualization technology, so that the slave 102 can freely and seamlessly access the virtual peripheral system.
Referring to fig. 2 to 4, in the present embodiment, a control method of a master-slave system is as follows:
the slave operation is synchronized to the master in the following way:
the master-slave system comprises a master and at least one slave, and the control method comprises the following steps:
step S201: triggering and updating the slave operation system;
step S202: the slave corresponding driver processes the update;
step S203: the slave drive Client layer processes the update;
step S204: the slave drive Client layer transmits the data and the command related to the update to the Host drive Host layer;
step S205: the Host drive Host layer sends the data and the command related to the update to the Host drive Demuxer layer;
step S206: the host correspondingly drives to execute the updating operation according to the data and the command related to the updating;
step S207: and the host operating system displays the updating result.
The above specific embodiments may be as follows: if the updating operation can be display updating, the slave operating system triggers display updating, the slave correspondingly processes the display updating according to the display driver, a display updating command and data are transmitted to the slave driver Client layer, and the slave driver Client layer receives the data and processes the display updating according to the updating command and the data;
in this embodiment, the slave driver Client layer preferably transmits the display update related data and command to the Host driver layer via PCIE/USB. After receiving the related data and command, the Host driver Host layer may distribute the data and command related to display update to the demuxer of the sub-screen (VGA, etc.), or distribute the data and command related to display update to the demuxer of HDMI-OUT, and the following two cases are described separately:
if the data and commands related to the display update are distributed to the Deumxer of the auxiliary screen (VGA and the like), the auxiliary screen drive responds to the display update, and finally the corresponding display update is carried out on the physical auxiliary screen of the host.
And if the data and the command related to the display updating are distributed to the Deumxer of the HDMI-OUT, the HDMI-OUT drives to respond to the display updating, then the HDMI-IN drives to respond to the display updating correspondingly, the virtual Shell responds to the display updating, and finally the main screen of the host machine correspondingly displays the updating.
Through the above steps, the dual-display of the slave display update can be realized (i.e. the physical sub-screen display update mentioned in the above embodiment 1, and the main screen of the host display update), and the dual-display single-display can also be realized, that is: only one of the two displays updates.
In other embodiments, other update operation commands may be used, such as: USB read-write, serial read-write, GPIO operation and the like.
Host operations are synchronized to the host in the following manner:
step S301: a host drives a Demuxer layer to receive an input instruction of peripheral IO equipment;
step S302: the Host drive Demuxer layer sends the input command to a Host drive Host layer;
step S303: the Host driving Host layer transmits the input instruction to the slave driving Client layer;
step S304: the slave drive Client layer sends the input instruction to a corresponding slave drive;
step S305: and the slave corresponding driver executes corresponding operation according to the input instruction.
The method for adding the CPU of the slave into the CPU pool by the host can adopt the following modes:
step S401: starting a slave operation system;
step S402: the slave computer calls a CPU registration driver;
step S403: calling a CPU registration driver by a slave driver layer;
step S404: the slave drive Client layer sends related data and commands to the Host drive Host layer;
step S405: the Host drives the Host layer to respond to the CPU registration according to the related data and commands;
step S406: the host responds to the CPU registration corresponding to the driver;
step S407: and the host updates the CPU pool and adds the slave CPU into the CPU pool of the host.
Through the steps, after the master machine and the slave machine are interconnected, the master machine can manage and dispatch a microprocessor (CPU) of the slave machine through the multi-core management system, if the master machine, the slave machine and the CPU are 4 cores, the CPU which can be dispatched by the master machine is 8 cores after expansion, and the multi-core performance of the master machine is indirectly expanded.
