Abstract
A method of dynamically switching mapping schemes for cache includes a microprocessor, a first mapping scheme, a second mapping scheme and switching circuitry for switching between the first mapping scheme and the second mapping scheme. The microprocessor is in communication with the cache through the switching circuitry and stores information within the cache using one of the first mapping scheme and second mapping scheme. Also, monitoring circuitry for determining whether one of instructions and load/store operations is using the cache is included. Further, the switching circuitry switches between the first mapping scheme and the second mapping scheme based on which one of instructions and load/store operations is using the cache.
