ABSTRACT:
A processing unit includes a plurality of subcircuits and circuitry for generating clock signals thereto. Detecting circuitry detects the assertion of a first signal indicative of a request for suspending operation of the processing unit and the assertion of a second signal indicating the state of operation of a coprocessing unit. Disabling circuitry is operable to disable clock signals to one or more of the subcircuits responsive to the first and second control signals.
