Abstract
In some embodiments, the invention includes a system having a processor and control circuitry. The control circuitry controls a setting of a body bias signal to control body biases provided in the processor to at least partially control a parameter of the processor, wherein the control circuitry controls the setting responsive to processor signal resulting for execution of software. The control circuitry may further control settings of a supply voltage signal and a clock signal to control the parameter. More than one parameter may be controlled. Examples of the parameters include performance, power consumption, and temperature.
