In Chapter 13, you learned how to code x86-64 assembly language functions that performed packed integer operations using 128-bit wide operands. In this chapter, you will learn how to perform similar operations using AVX2 instructions and 256-bit wide operands. The first section illustrates basic integer arithmetic. The second section spotlights familiar image processing techniques.

Using AVX2 instructions and 256-bit wide integer operands is not much different than ...
