The previous chapter explained SIMD fundamentals including packed types, arithmetic calculations, and data manipulation operations. It also highlighted a few details regarding the history of x86-AVX and its computational capabilities. The focus of this chapter is AVX integer arithmetic using 128-bit wide operands. The first section contains several concise source code examples that illustrate how to use C++ SIMD intrinsic functions to perform packed integer arithmetic. This followed ...
