ABSTRACT:
An apparatus comprising floating point circuitry and first logic coupled to at least one flag in a processor control register (e.g. one of the control registers in the Intel Architecture brand processor or a processor compatible therewith) and the floating point circuitry and for coupling to a clock which drives the floating point circuitry. The first logic allows the clock to clock the floating point circuitry when the at least one flag has a first state. The first logic further prevents the clock from clocking the floating point circuitry when the at least one flag has a second state.
