Abstract
Systems and methods for control of integrated circuits comprising body-biasing systems. In accordance with a first embodiment of the present invention, a desirable power condition of a computer system comprising a microprocessor is determined. Body biasing voltage information corresponding to the power condition is accessed. A voltage supply coupled to a body terminal of the microprocessor is commanded to generate a voltage corresponding to the body biasing voltage information corresponding to the power condition.
Claims21
A computer system comprising:
- a plurality of data storage locations comprising body biasing voltage information corresponding to a plurality of power modes of said computer system;
- a voltage supply to generate a body biasing voltage for circuitry of said computer system according to said body biasing voltage information;
- and
- circuitry to selectively couple said body biasing voltage information from one of said plurality of data storage locations corresponding to one of said plurality of power modes to said voltage supply.
A method for determining a body biasing voltage applied to a microprocessor comprising:
- determining a desirable power condition of a computer system comprising said microprocessor;
- accessing body biasing voltage information corresponding to said power condition;
- and
- commanding a voltage supply coupled to a body terminal of said microprocessor to generate a voltage corresponding to said body biasing voltage information corresponding to said power condition.
An integrated circuit comprising:
- a plurality of registers comprising body biasing voltage information corresponding to a plurality of power modes of a computer system;
- a first voltage supply to generate a body biasing voltage for p-type devices of a microprocessor of said computer system according to said body biasing voltage information;
- a second voltage supply to generate a body biasing voltage for n-type devices of said microprocessor of said computer system according to said body biasing voltage information;
- and
- circuitry to selectively couple said body biasing voltage information from one of said plurality of registers corresponding to one of said plurality of power modes to said first and second voltage supplies.
