Abstract

PURPOSE: To improve unit processing performance by providing an executing method for software routine SWR and microprogram routine μPGR and then by selecting and executing either of SWR and μPGR.
CONSTITUTION: Of the information processing system on the dynamic microprogram μPG control system, CPU10 is equipped with control memory loading part CSLDU11 with a dedicated memory unit part applied with a microprocessor, control part CU12 and arithmetic part ALU13. A program in CSLDU11 is started by an instruction from CPU and through system controller SCU15, loading is done from main memory unit MM14 or external memory unit IOM16 to rewritable control memory part ECS of CU12. At the time of the transfer of μPG to ECS or in a unloading state, SWR performs the process and after the loading, the process is carried out by μPG stored in ECS. Therefore, the overhead of the replacement of μPG is eliminated and the processing performance of this unit can be improved.
