Abstract
A processor having a multi-Vt critical path is provided that includes both low-Vt devices and high-Vt devices. If the processor is operating in a high performance mode, the multi-Vt critical path is controlled so as to use the low-Vt devices. Conversely, if the processor is operating in a low power mode, the multi-Vt critical path is controlled so as to use the high-Vt devices. In this fashion, the complication of multiple processing cores is avoided in that a single processor core can operate in both the high performance mode and in the low power mode.
