Abstract

PURPOSE: To detect rapidly the hang-up concerning the main memory access in the minimum monitoring time by resetting the clocking means such as the counter and starting the clocking when the condition display of the memory bank designated by the address is changed from the unused condition display to the using condition display.
CONSTITUTION: A bank condition detecting circuit 6 connected to a request buffer register 10 for the test is the same as the conventional one, branches the output of an OR gate 16 of the circuit and connects to a flip-flop 21 to generate the signal for controlling a counter 20 which is a clocking means. The flip-flop 21 generates the resetting pulse of the counter 20 together with a flip-flop 22 and a gate 23. Thus, when the necessary address is set to the request buffer register 10, the condition display of the equivalent memory bank can be monitored and the hang-up can be detected rapidly.
