Abstract

PURPOSE:To execute the processing corresponding to variable length operation instruction at high speed, by providing a variable operation instruction processing circuit in an operation execution section. CONSTITUTION:The function to be executed in an operation section 9 of a variable length operation instruction processing circuit 7 is set to a function indication controlling register 12. On the other hand, at the section 9, first the 1st operand is set to an internal register 8 via a bus 10 from an external register 15, the 2nd operand is set to the register 15 and they are applied to the section 9 respectively for operation. The result is set to an output register 16. A conditional code is set at 13 with the processing of the section 9 during that time and the branch condition of the microprogram is given via a control trigger 14.
