Abstract

PURPOSE: To reduce length of steps of instructions by providing an address register which drives a register file directly and by setting the addressing signal of the register file to the address register in the preceding-stage cycle of the execution cycle.
CONSTITUTION: Logical operation part 10 is constituted by logical operation function elements such as a micro processor, and this operation part 10 is provided with a register file constituted by external two-port RAM 20, and further, address register 21 and micro instruction register 23 connected to control memory unit 22 are provided. The read access of operation part 10 is set to register 21 through selector 24 to drive RAM 20 directly, and further, the micro instruction read from register 23 is supplied to selector 35, and the write address is supplied from selector 35 to RAM 20 through address register 36. In cycles before and after the execution cycle, the addressing signal of RAM 20 is set through register 21 to reduce length of steps of the instruction.
