Arithmetic system having pipeline structure arithmetic means |
摘要 |
An arithmetic system includes an arithmetic unit of a pipeline structure for executing arithmetic operations for instructions which require different arithmetic cycles. The arithmetic unit executes N arithmetics in pipeline for N instruction at maximum. Initiation of arithmetic operation for a new instruction in the arithmetic unit is indicated by an indicator which detects that each of the instruction executed in the arithmetic is N cycles before completion of the execution and allows arithmetic operation for the new instruction to be initiated in the succeeding cycle.
