Dynamically configurable clocking scheme for demand based resource sharing with multiple clock crossing domains

摘要

A first clock signal having a first frequency is applied to drive a first module. A second clock signal having a second frequency is applied to drive a second module. The second frequency is different from the first frequency. A third clock signal is selectively applied with a frequency substantially the same as the first frequency to drive at least one portion of a resource to allow the first module to access the one portion of the resource. The third clock signal is selectively applied with a frequency substantially the same as the second frequency to drive at least the one portion of the resource to allow the second module to access the one portion of the resource.
