Controlling configurable peak performance limits of a processor

A method comprising:

• receiving a set of configurable frequency limit values in a first logic of a multi-domain processor;
• and
• storing a corresponding one of the set of configurable frequency limit values or one of a set of maximum peak frequency values as a resolved value in each field of a configuration storage of the multi-domain processor, wherein the set of maximum peak frequency values are obtained from a non-volatile storage of the multi-domain processor and the set of configurable frequency limit values are obtained during runtime of the multi-domain processor to prevent the multi-domain processor from reaching a constraint during turbo mode operation.

A system comprising:

• a multicore processor including a plurality of cores, a non-volatile storage to store a plurality of maximum peak operating frequency values, each of the maximum peak operating frequency values a function of a given number of active cores, a limit storage to store a plurality of configurable clip frequency values, a power control unit (PCU), and a frequency limit control logic to store in each field of a configuration storage a corresponding one of the maximum peak operating frequency values stored in the non-volatile storage or a configurable clip frequency value stored in the limit storage, the configurable clip frequency value based on a priori information regarding a workload to be executed on the multicore processor;
• and
• a dynamic random access memory (DRAM) coupled to the multicore processor.
