MEMORY ACCESS DETERMINATION CIRCUIT, MEMORY ACCESS DETERMINATION METHOD, AND ELECTRONIC DEVICE

摘要

PPROBLEM TO BE SOLVED: To improve the hit ratio of a cache memory and increase processing speed. PSOLUTION: A memory access determination circuit includes a counter 1 that counts a value based on a first value of change, and a control unit 2 that makes a cache determination of the cache memory 6 based on an address corresponding to an output of the counter 1. If a determination is made that there is a cache error in the control unit 2, the counter 1 counts by switching the first value (m) of change to a second value (n) of change that is different from the first value (n) of change. The cache determination is made based on the control unit 2 and a count value based on the second value (n) of change. PCOPYRIGHT: (C)2010,JPO&INPIT
