Advanced Vector Extensions (AVX)
Daniel Kusswurm · Apress eBooks · 2014
In the previous seven chapters, you learned about the SIMD processing capabilities of MMX and x86-SSE. MMX introduced elementary integer SIMD arithmetic and related operations to the x86 platform. These capabilities were extended by x86-SSE to include wider operands, additional registers, and enhanced floating-point arithmetic using scalar and packed operands. This chapter examines the x86’s most recent SIMD augmentation, which is called Advanced Vector Extensions (x86-AVX). These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
