ps_2_0 Instructions

This section contains reference information for the pixel shader version 2_0 instructions.

There are several types of pixel shader instructions, as shown in the table. Columns to the right mean the following:

  • Instruction slots - Number of instruction slots used by each instruction.
  • Setup - A pixel shader must have a version instruction and it must be the first instruction.
  • Arithmetic - These instructions provide the mathematical operations in a shader.
  • Texture - These instructions are used to load and sample texture data, and to modify texture coordinates.
  • New - These instructions are new to this version.
