Patent ID: 6957163

Claim:
In an integrated circuit system having access to a reference data table for holding information used to control at least one circuit block in said system and having at least two of a power supply circuit, a body bias control circuit, a clock delivery circuit, a temperature monitor circuit, and a configuration control circuit, a method of improving the performance of said system comprising (A) obtaining system performance data by testing said system at at least two parameters selected from the group consisting of different supply voltages, different body-bias voltages, different clock speeds, different temperatures, different data bus widths, different circuit block configurations, and combinations thereof, where at least one of said parameters is different temperatures; and (B) entering values based on said data into said reference data table, where said temperature monitor circuit and at least one of said power supply circuit, said body bias control circuit, said clock delivery circuit, or said configuration control circuit is controlled using said values.
