ABSTRACT:
Circuits, methods, and apparatus that provide for partial texture load instructions. Instead of one instruction that may take several shader passes to complete, several instructions are issued, where each instruction is an instruction to retrieve a part or portion of a texture. While each instruction is performed, the other shader circuits can perform other instructions, thus increasing the utilization of the shader circuits when large textures are read from memory. Since several shader passes may be required to read a texture, if a particular instruction needs the texture, one exemplary embodiment reorders instructions such that other instructions are performed before the particular instruction that needs the texture.
