ABSTRACT:
A cache controller structure and method are provided for managing cache access for a computer system. The computer system has a processor having a direction flag and configured to run a repetitive string operation, wherein the string operation is configured to sequentially access a targeted memory block for each repetition depending on the state of the direction flag. A cache controller logic is provided to control a cache embedded in the processor while the processor executes string operations. The cache controller is configured to manipulate the cache lines responsive to the direction flag and to a position of a targeted memory block within a cache line. In some embodiments, the controller logic is also configured to manipulate the cache lines responsive to a repetition parameter value within the string operation.
