  • Method and apparatus for implementing an algorithm associated with stored information
    Patent number: 4607331
    Abstract: A circuit and method for implementing a predetermined data replacement algorithm associated with a fast, low capacity cache, such as least recently used (LRU), which is fast and which minimizes circuitry is provided. A latch stores the present status of the replacement algorithm, and an address control signal indicates which one of n sets of stored information in the cache has been most recently accessed, where n is an integer. The predetermined algorithm is implemented by a predetermined permutation table stored in a translator which provides an output signal in response to both the present status of the replacement algorithm and the address control signal. The output signal indicates which one of the n sets of stored information in the cache may be replaced with new information.
