Abstract

PURPOSE:To select an optional register among multi-purpose memory registers, by setting up one-bit information for discriminating the contents of every field, in the fields of a processor on a microprogram control system. CONSTITUTION:Multipurpose memory registers 41-48 connecting an address bus 31 to data buses 32 and 33 are provided; one memory cell consists of two fields and in single memory operation, reading from an writing to one of two groups of registers 41 and 42, and 47 and 48 are performed. To the most significant one bit of each of fields 61-64 of microinstructions, a bit for discriminating between the multipurpose register and an indication register is assigned, thereby selecting freely a register which holds a memory address and memory data among the multipurpose memory registers 41-48. Therefore, a waste of transfer time between registers interfacing to a memory is eliminated in the main processing of memory access.
