Abstract
Power down circuitry in a processor for controlling power delivered to functional units of the processor, comprising first and second power down circuits. The first power down circuit comprises a state machine having a decoded instruction as input and a control signal as output. The control signal disables a clock signal to a floating point unit (FPU) when the decoded instruction is not a floating point instruction. The second power down circuit comprises a prediction circuit that generates a predict signal when a cache access cannot occur. The predict signal disables a clock signal to a cache.
