Abstract
An an address generator generates a read address. It is detected whether the generated read address is continuous to the read address previously generated. A cache unit control circuit controls the read data to be directly output to a requester of the read data without passing the read data through a cache RAM, if a cache miss occurs, and if it has been detected that the two addresses are continuous. As a result, the subsequent operations can executed even if the present operation has not been completed.
