Abstract
Abstract An improved method and system for storing iterative data associated with an iterative process within a cache. A first iteration of an iterative process, having a plurality of steps, is executed. During the execution of each one of the plurality of steps, iterative data associated with each one of the plurality of steps is stored within the cache, and identified with the appropriate one of the plurality of steps. During the execution of a second iteration of the iterative process, iterative data generated by one of the plurality of steps is compared with the stored iterative data from the first iteration which is identified with the one of the plurality of steps. If the identified iterative data matches the generated iterative data then a method address stored within the identified iterative data is used to retrieve the method from main memory and execute it without using a standard look up table.
