摘要： A system for pushing data, the system includes a source node that stores a coherent copy of a block of data. The system also includes a push engine configured to determine a next consumer of the block of data. The determination being made in the absence of the push engine detecting a request for the block of data from the next consumer. The push engine causes the source node to push the block of data to a memory associated with the next consumer to reduce latency of the next consumer accessing the block of data.

摘要： A method and apparatus for managing texture mapping data in a computer graphics system, the system including a host computer, primitive rendering hardware and a textured primitive data path extending between the host computer and the primitive rendering hardware. The host computer passes textured primitives to be rendered by the system using corresponding texture mapping data to the primitive rendering hardware over the textured primitive data path. The host computer has a main memory that stores texture mapping data corresponding to the textured primitives to be rendered. The primitive rendering hardware includes a local texture memory that locally stores the texture mapping data corresponding to at least one of the textured primitives to be rendered. When texture mapping data corresponding to one of the textured primitives to be rendered is stored in the host computer main memory but not within the local texture mapping memory, the texture mapping data corresponding to the one of the textured primitives is downloaded from the host computer main memory to the local texture mapping memory through a texture mapping data path that is separate from the textured primitive data path.

摘要： A texture mapping computer graphics system includes a host computer with a main memory that stores texture data including a plurality of texels. A local memory stores at least a portion of the texture data. A local memory access unit, coupled to the local memory, accesses texels from the local memory. A texel data buffer, coupled to the local memory access unit, stores a limited number of texels most recently accessed by the access unit from the local memory. A texel interpolator, coupled to the texel data buffer, reads texels from predefined locations of the texel data buffer. The access unit accesses texels from the local memory only when such texels are unavailable to be re-read from the texel data buffer. A circuit, coupled to the interpolator and the local memory access unit, determines whether a current texel is available to be re-read from the texel data buffer. The circuit includes a comparator that compares an address of the current texel with an address of a texel most recently accessed from the local memory.

摘要： Methods and apparatus for maximizing column address coherency for serial and parallel port accesses to a dual port frame buffer. Performance of the serial port of the frame buffer is greatly improved by separating the page boundaries in the horizontal direction (i.e., scan line organized), while performance of the parallel port of the frame buffer is enhanced by organizing the page boundaries for rectangular areas of the display. Performance at both ports may be maximized at the same time by organizing the video random access memory (VRAM) into tiles and vertically barrel shifting the scan line data at a fixed interval across the video display. During operation, the serial port output looks like an entire row of data while it has actually output parts of N rows of data from two separate rows of memory chips which are changed at the fixed interval. This approach allows the parallel port to organize columns N times higher in the vertical direction. As a result, the page boundaries are N times as far apart in the vertical direction, thereby improving output performance.
