X86-SSE Programming – Text Strings

  • Daniel Kusswurm
Chapter

Abstract

The sample code from the previous three chapters focused on using the x86-SSE instruction set to implement numerically-oriented algorithms. In this chapter, you learn about the x86-SSE text string processing instructions. The x86-SSE text string instructions are somewhat different than other x86-SSE instructions since their execution depends on the value of an immediate control byte. The first section of this chapter explains the various control byte options and their operation paradigms. It also discusses several programming precautions that you must observe when using SIMD techniques to process text strings. In the second section, you examine a couple of sample programs that illustrate basic use of the x86-SSE text string instructions.
