Abstract
PURPOSE: To realize the test for the frequency of reference of each order such as the data or the program of each address by adding the count value memory cell to record the reference frequency to the memory device, thus performing the evaluation for the debug and the system of the program.
CONSTITUTION: The read/write is carried out for the information of each cell 2 in accordance with the state of read/write control signal 5. Signal 5 is applied also to each count value memory cell 7 with every read/write, and the contents of cell 7 is stored in counting circuit 8. Circuit 8 carries out the prescribed action based on control signal 10. As a result, the debug and the like can be done for the program while giving the test to the reference frequency of each address.
