Abstract
A power control system for a microprocessor, having multiple parallel operated execution units, functions to disable some of the execution units to conserve power and/or reduce heat. The execution units are disabled by preventing the application of clock pulses to these execution units. This operation is effected by a power control unit which enables and disables gates coupled between a source of clock signals and the execution units.
