Abstract
A computer module includes a central processing unit capable of operating at a first performance level and capable of operating at a second performance level in response to configuration signals, and a control logic coupled to the central processing unit for receiving configuration signals and for generating the performance configuration signals, the performance configuration signals comprising a bus clock, a speed multiplier, and an operating voltage, the control logic having a clocked control for receiving the performance configuration signals and in response specifying the speed multiplier, clock configuration signals, and voltage configuration signals, a clock driver coupled to the clocked control logic for receiving the clock configuration signals and in response for outputting the bus clock, and a voltage converter coupled to the clocked control logic for receiving the voltage configuration signals and in response outputting the operating voltage.
