Modeling Structured SIMD Control FLow Constructs in an Explicit SIMD Language

摘要

Constructs may express SIMD control flow that can be efficiently implemented on a SIMD machine with support for SIMD control flow. The execution semantics of constructs serve as a functional specification for an emulation implementation in the central processing unit (CPU), a non-SIMD machine, using conventional C++ compiler such as GCC or Microsoft Visual C++ without any modification to the conventional compiler in some embodiments.
