Abstract
When the cache memory unit reads the last word of a page of the cache memory, the external memory interface reads ahead data of a prescribed number of pages ahead of the relevant page. Thus, data corresponding to the access request to the external main memory is always held in the cache memory. This prevents degradation of parallel processing capability of the data driven type information processing apparatus.
