Abstract
A processor includes a first level of cache memory and a first set of instructions configured to implement a first cache coherency protocol. The processor also includes a second set of instructions configured to implement a second cache coherency protocol and a cache coherency protocol selector having at least two choice-states. The processor further includes a cache coherency implementer configured to implement the first cache coherency protocol or the second cache coherency with respect to the first level of cache memory based on a selected choice-state of the cache coherency protocol selector.
