Jun 22, 2021 · After executing the dense instructions, their results are restored to the original instructions. However, CR has a significant performance and ...
This paper proposes a novel approach to improve execution efficiency in predicated vector codes, the Compiler-Assisted. Compaction/Restoration (CACR) technique.
Compacted elements form an equivalent dense vector instruction. After executing the dense instructions, their results are restored to the original instructions.
Baseline CR delays predicated SIMD instructions with inactive elements, compacting active elements from instances of the same instruction of consecutive loop ...
