ABSTRACT:
Methods and apparatus are disclosed for realizing an integrated cache unit which may be flexibly used for cache system design. The preferred embodiment of the invention comprises both a cache memory and a cache controller on a single chip. In accordance with an alternative embodiment of the invention, the cache memory may be externally located. Flexible cache system design is achieved by the specification of desired cache features through the setting of appropriate cache option bits. The disclosed methods and apparatus support this user oriented approach to flexible system design. The actual setting of option bits may be performed under software control and allows a high performance cache system to be designed with few parts, at low cost and with the ability to perform with high efficiency.
