Superword Level Parallelism

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Superword level parallelism (SLP) is a vectorization technique based on loop unrolling and basic block vectorization. It is distinct from loop vectorization algorithms in that it can exploit parallelism of inline code, such as manipulating coordinates, color channels or in loops unrolled by hand.[1] It is available in the gcc compiler since version 4.3.

Also supported by LLVM.
