Abstract

PURPOSE: To prevent processing operation from deteriorating by facilitating program generation by connecting corresponding areas of plural working registers and those in a memory unit to a common bus via gates.
CONSTITUTION: Four working registers WR0WWR3 and working registers WR4W WR7 provided in memory unit MEM are connected to common bus BUS via gates. When registers WR0 and WR2 are free although three working registers should be used and WR1 and WR3 are in use, a microprogram programmer completes a program by considering free registers among registers WR4WWR7 residing in MEM usable working registers, as they are, even if they do not reside. Namely, gate on- off signals WR0B and WR2B are generated and registers WR0 and WR2, bus BUS, adder ACC, etc., are connected, so that information transmission and arithmetic processing will be performed.
