Abstract
An example processor that includes a register, a cache, a processor core, and a programmable logic circuit. The register may store a first prefetch value indicating a first amount of time to prefetch data from a memory prior to an execution of a subsequent instruction that uses the data. The processor core may be coupled to the cache and the register. The processor core may execute a prefetch instruction to access the data from the memory, store a copy of the data in the cache, and execute the subsequent instruction. The programmable logic circuit may be coupled to the processor core. The programmable logic circuit may determine whether the first amount of time is insufficient to prefetch the data for the execution of the subsequent instruction and change the first prefetch value to a second prefetch value when the first amount of time is insufficient.
