More Information
Summary:There is provided a data processing apparatus comprising table circuitry to store a table that indicates, for a program counter value of an instruction that performs a memory access operation at a memory address, one or more offsets of the memory address and an associated confidence for each of the one or more offsets. Prefetch circuitry prefetches data based on each of the offsets in dependence on the associated confidence. Each of the offsets of the memory address is dynamically determined.
