X86-AVX Programming - New Instructions

Abstract

In the previous three chapters, you learned how to manipulate scalar floating-point, packed floating-point, and packed integer operands using the x86-AVX instruction set. In this chapter you how to use some of the new programming features included with x86-AVX. The chapter begins with a sample program that illustrates the use of the cpuid instruction, which can be used to determine if the processor supports x86-SSE, x86-AVX, or a specific instruction-group feature extension. This is followed by collection of sample programs that explain how to use x86-AVX’s advanced data-manipulation instructions. The final section of this chapter describes some of the x86’s new general-purpose register instructions.
