Abstract:
An apparatus comprises a plurality of cores and a controller coupled to the cores. The controller is to lower an operating point of a first core if a first number based on processor clock cycles per instruction (CPI) associated with a second core is higher than a first threshold. The controller is operable to increase the operating point of the first core if the first number is lower than a second threshold.
