Microprogram control system

Abstract

Abstract PURPOSE:To reduce the size of an arithmetic device which is controlled by one microprogram and shorten a processing time by parallel of processing by performing one operation partially by plural microprograms. CONSTITUTION:The sart of an operation is indicated to microprogram controllers 1 and 6 at the same time. The microprogram controller 1 while controlling a program sequence by itself indicates an arithmetic device 3 to read data out of a register group and store it memory. The microprogram controller 6 while controlling the program sequence by itself indicates an arithmetic device 8 to read memory for old time control information on a task and a timer and generate and store new time control information on the task in the memory. Consequently, the operation is carried out by performing said processes in parallel.
