In Chapter 2, you learned how to use AVX C++ SIMD intrinsic functions to perform packed integer arithmetic and other data manipulation operations using 128-bit wide operands. In this chapter, you will learn how to exploit AVX2 to perform similar operations using 256-bit wide packed integer operands. Chapter 4 is partitioned into two sections. The first section highlights SIMD integer arithmetic, unpacking and packing, and size promotions. The second section includes source code ...
