PREFETCHING ASSOCIATED WITH PREDICATED LOAD INSTRUCTIONS

摘要

Technology related to prefetching data associated with predicated loads of programs in block-based processor architectures is disclosed. In one example of the disclosed technology, a processor includes a block-based processor core for executing an instruction block comprising a plurality of instructions. The block-based processor core includes decode logic and prefetch logic. The decode logic is configured to detect a predicated load instruction of the instruction block. The prefetch logic is configured to calculate a target address of the predicated load instruction and issue a prefetch request to a memory hierarchy of the processor for data at the calculated target address.
