Abstract A method and system for patching instructions in a 3-D graphics pipeline. Specifically, in one embodiment, instructions to be executed within a scheduling process for a shader pipeline of the 3-D graphics pipeline are patchable. A scheduler includes a decode table, an expansion table, and a resource table that are each patchable. The decode table translates high level instructions to an appropriate microcode sequence. The patchable expansion table expands a high level instruction to a program of microcode if the high level instruction is complex. The resource table assigns the units for executing the microcode. Addresses within each of the tables can be patched to modify existing instructions and create new instructions. That is, contents in each address in the tables that are tagged can be replaced with a patch value of a corresponding register.
