Abstract:
A method of optimizing performance of a multi-core chip having a plurality of cores includes the steps of determining a Vdd-frequency SCHMOO characteristic for each of the plurality of cores individually; saving data indicative of the Vdd-frequency SCHMOO characteristics for each of the plurality of cores; configuring the cores to obtain a configuration providing at least one of optimum power consumption and optimum performance, for a given workload, based on the saved data; and saving the configuration such that it may be updated and used on at least one of a periodic and a continual basis.
