Abstract

PURPOSE:To pick up the operation exceptional information produced earliest, by checking the presence of the production of operation exception at the end of one instruction. CONSTITUTION:In the process that the element is operated and stored with the pipeline processing, if the operational exception is produced at the steps 5-0-5-4, the information is set to the step stages 9-0-9-4 corresponding to the exceptional information pipeline 8. If the exceptional information is set to the step stage 9-(i+1) from the step stage 5-(i+1) of the pipeline operation section 4 in the timing when the exceptional information from the step stage 9-i is shifted to the step stage 9-(i+1), the exceptional information from the step stage 5-(i+1) is ignored. That is, when the exceptional information is set to the step stage 9-4 at first and set to the exceptional information stack 10 at the next cycle, the gate G is OFF. By checking the content of the stack 10, the production of operational exception can be known.
