Predictive historical cache memory |
摘要 |
A cache memory functioning as a circular buffer for use as a part historical, part predictive cache memory is provided. A first register contains data having a value corresponding to a cache memory location of a last instruction executed by a processor and a second register contains data having a value corresponding to a memory location in the cache memory of a last prefetched instruction. Prefetching of instructions from a main memory to the cache memory is disabled if the difference between the values in the first and second pointer registers exceeds a predetermined amount.
