One embodiment of the present invention sets forth a technique for executing a software method within a graphics processing unit (GPU) that minimizes the number of clock cycles during which the graphics engine is idled. The function of the software method is performed by a firmware method that is executed by a processor within the GPU. The firmware method is executed to access and optionally update the state stored in the GPU. Unlike execution of a conventional software method, execution of the firmware method does not require an exchange of information between a CPU and the GPU. Therefore, the CPU is not interrupted and throughput of the CPU is not reduced. |
