Abstract

Dynamic control of prefetching based on prefetching accuracy in a computing system, and related methods and computer readable media. The computing system comprises a processor that includes one or more Central Processing Unit (CPU) cores each having an associated cache memory. The CPU core(s) is configured to generate a value indicative of a prefetching accuracy of the CPU core for prefetching of data, instructions, or both data and instructions from system memory external to the processor for storage in the cache memory for the CPU core and control the prefetching performed by the CPU core based on the value indicative of the prefetching accuracy. In this manner, the number of memory access requests for prefetching is reduced when prefetching accuracy is below a certain threshold, which in turn mitigates memory bandwidth contention, particularly in a multi-CPU core processor.
