Abstract

PURPOSE: To shorten the cache reading time by storing the cache read data into a data buffer and then reading out the read data en bloc.
CONSTITUTION: When a cache memory is set in a read mode, a data array DA 11 and the data buffer word address are sequentially counted up and at the same time the read data on the DA 11 is stored in a data buffer DB 18. Meanwhile the data buffer word location is also successively counted up. Then the DB 18 is set in a shift mode and the contents of the DB 18 can be completely read out via a shift path. Thus the reading time is shortened for all contents of the cache memory.
