Abstract

A method and an apparatus for reducing an effect of local process variations of a digital circuit on a hardware performance monitor includes measuring a set of performance values (c, c. . . c) of the digital circuit by n identical hardware performance monitors, where n is a natural number greater than 1, determining an average value cof the measured performance values (c, c. . . c), as an approximation of an ideal performance value c, selecting one performance value cof the set of performance values (c, c. . . c) by a controller, comparing the performance value cwith a reference value cby a controller the controller, resulting in a deviation value Δc, and controlling an actuator by using the deviation Δc for regulating the local global process variations to the approximation cof the ideal performance value c.
