Abstract

PURPOSE: To reduce the risk of over run without temporary abandonment of the execution right of the front end, by changing the precedence of requests from the front end according to the situation.
CONSTITUTION: Output signal PHISWPHnS of front ends 3-1W3-n are input to OR circuit 7, and resoective FF 4-1W4-n and 5-1W5-n are reset or set by the output of circuit 7. Contents of a pair of high precedence request signals and low precedence request signals of FF 4-1W4-n and 5-1W5-n are changed freely by the micro instruction of the scanning of FF 4-1W4-n and 5-1W5-n input to circuit 7. Then, the precedence is selected in precedence determining and selecting circuit 6 without temporary abandonment of the execution right of front ends 3-1W3-n, so that the risk of over run is reduced.
