摘要： A configurable filter module for providing shared filter resource between an overlay engine and a texture mapping engine of a graphics system. The configurable filter may comprise a plurality of linear blend units each of which receives data input from one of the overlay engine and a mapping engine cache, and generates a linear blend filter output respectively; and a filter output multiplexer which receives data output from the linear blend units and selects a proper byte ordering output, wherein the linear blend units serve as an overlay interpolator filter to perform linear blending of the data input from the overlay engine during a linear blend mode, and serve as a texture bilinear filter to perform bilinear filtering of the data input from the mapping engine cache during a bilinear filtering mode.

摘要： A method for communicating graphics device status information to a graphics driver. Status of a graphics device is checked to determine whether the graphics device is ready to process a next instruction. A location in cacheable memory accessible to a graphics driver is updated with the status. The graphics driver reads the status to determine when to generate the next instruction for processing by the graphics data. A first instruction to be forwarded to the graphics device is generated. A status in an operating register in the graphics device is updated indicating that an event is being monitored. The updating is performed in response to receipt of the first instruction by the graphics device. The status is written to a second cacheable location in system memory accessible to the graphics driver. A second instruction is generated by the graphics driver to provide a predetermined address and instruction completion data to the graphics device.

摘要： A special instruction processor, such as a floating point accelerator processor, that processes a special class of instructions. Each instruction identifies the number of operands to be processed as well as the number of data words required to be transferred for each operand. The central processing unit retrieves and decodes each instruction, and transfers the special instructions to the special instruction processor. Both processors decode the special instructions to determine the numbers of operands and data words to be transferred. The central processing unit retrieves the data words from memory and transmits them to the special instruction processor. The special instruction processor processes the instruction and signals the central processor when finished. The central processor then causes the special instruction processor to transmit the processed data back to the central instruction processor.
