MODULATION AF PROCESSORKERNEOPERATIONER

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reducing processor latency through the use of dedicated cores. In one aspect, a method includes a multi-core processor having n cores, including, selecting k cores of the n cores of the multi-core processor to perform dedicated low-latency operations for the n-core processor, where k is less than n, m cores are unselected, and each core of the multi-core processor has a rated core capacity. The methods operate the selected k cores at less than the rated core capacity such that k cores are collectively underutilized by an underutilized capacity and operate one or more of the m cores at a capacity in excess of the rated core capacity such that the m cores operate at a collective capacity that exceeds a collective capacity of the rated core capacities of the m cores.
