Abstract

PURPOSE: To reduce the latency time of an execution processing stage by providing a signal circuit to instruct the next instruction start to an advance processing stage and a signal circuit to instruct the clock stop to the advance processing stage in an advanced control-system information processing unit.
CONSTITUTION: Instruction words are subjected to the processings such as operand address calculation in instruction processing I part of advance processing stage 21, and are sent to cache C part 23. C part 23 reads out the operand, and sends it to execution processing E part 25 of execution processing stage 27 at the next clock. Advance control part 24 interprets instruction words; and in case of an instruction processed at one clock, instruction words are sent to C part 23 from I part 22, and simultaneously, the next instruction words are sent to I part 22. Execution control part 26 is provided with a timer circuit to detect the time required for the advance processing of the next instruction dependent upon the advance processing stage, and signal 40 is sent to advance control part 24 to stop the clock of the advance processing stage. As a result, the fluctuation of the processing speed of the advance proccessing stage and the execution processing stage is absorbed, so that the latency time of the execution processing stage can be eliminated or reduced.
