ABSTRACT:
An integrated circuit device provides an operational set point indicator. The operational set point indicator is utilized for obtaining a plurality of operational set points. Each of the plurality of operational set points can be a pair of an operational voltage and an operational frequency for application to the integrated circuit device. The operational set point indicator can be, for example, a Schmoo Class Register, a Device Identification Register, or actual operating condition information of the integrated circuit device. The Schmoo Class Register and the Device Identification Register are utilized to identify a performance state table in memory. The actual operating conditional information can be one or more entire Schmoo Plots for the device or a subset of such information. Operational set points are used during operation of the integrated circuit device, for example, in power management applications.
