Abstract
During manufacture, an operating range for dynamic voltage and frequency scaling can be established. A nominal operating point is identified based on a design nominal operating frequency for a computer processor. The nominal operating point comprises a nominal operating voltage identified for the design nominal operating frequency. In dependence upon the nominal operating point, an operating range of frequency and voltage over which the computer processor is to function is determined. Information specifying the nominal operating point and the operating range is stored in non-volatile storage associated with the computer processor.
