摘要: The invention sets forth an approach to context switching that utilizes scan chains modified to perform context switching operations. The design requires substantially less additional silicon area and design engineering effort than existing context switch approaches, while operating substantially faster and providing additional debug observability during context switching operations.

摘要: An apparatus and method for converting color data from one color space to another color space. A driver determines that a set of shader program instructions perform a color conversion function and the set of shader program instructions are replaced with either a single shader program instruction or a flag is set within an existing shader program instruction to specify that output color data is represented in a nonlinear color format. The output color data is converted to the nonlinear color format prior to being stored in a frame buffer. Nonlinear color data read from the frame buffer is converted to a linear color format prior to shading, blending, or raster operations.

摘要: An output buffer in a multi-threaded processor is managed to store a variable amount of output data. Parallel threads produce a variable amount of output data. A controller is configured to determine how much output buffer space is needed per thread and how many threads can execute in parallel, given the available space in the output buffer. The controller also determines where each thread writes to in the output buffer.
