PURPOSE:To shorten the processing time, by checking whether instructions can be executed or not in parallel. CONSTITUTION:Control memories 33-1-33-4 are incorporated in check parts 21-2-21-4 connected in parallel. When a request flag 26-1 is turned on, a preceding stage request flag controlling part 25 determines one of check parts 21-1- 21-4. One of request acceptance flag registers 22-1-22-4 which corresponds to the determined check part out of check parts 22-1-22-4 is turned on to fetch data into one of input registers 32-1-32-4. When registers 22-1-22-4 are turned on, check parts 21-1-21-4 check whether instructions can be executed or not. |
