    摘要: One embodiment of the present invention sets forth a technique for capturing and holding a level of an input signal using a latch circuit that presents a low number of loads to the clock signal. The clock is only coupled to a bridging transistor and a pair of clock-activated pull-down or pull-up transistors. The level of the input signal is propagated to the output signal when the storage sub-circuit is not enabled. The storage sub-circuit is enabled by the bridging transistor and a propagation sub-circuit is activated and deactivated by the pair of clock-activated transistors.

    摘要: Methods, apparatuses, and systems are presented for caching. A cache memory area may be used for storing data from memory locations in an original memory area. The cache memory area may be used in conjunction with a repeatedly updated record of storage associated with the cache memory area. The repeatedly updated record of storage can thus provide a history of data storage associated with the cache memory area. The cache memory area may be loaded with entries previously stored in the cache memory area, by utilizing the repeatedly updated record of storage. In this manner, the record may be used to “warm up” the cache memory area, loading it with data entries that were previously cached and may be likely to be accessed again if repetition of memory accesses exists in the span of history captured by the repeatedly updated record of storage.

    摘要: One embodiment of the present invention sets forth a technique for technique for capturing and storing a level of an input signal using a single-trigger low-energy flip-flop circuit that is fully-static and insensitive to fabrication process variations. The single-trigger low-energy flip-flop circuit presents only three transistor gate loads to the clock signal and none of the internal nodes toggle when the input signal remains constant. The output signal Q is set or reset at the rising clock edge using a single-trigger sub-circuit. A set or reset may be armed while the clock signal is low, and the set or reset is triggered at the rising edge of the clock.

    摘要: A graphics system coalesces Z data and color data for a raster operations stage. The Z data and color data are stored in a memory aligned tile format. In one embodiment, rendering modes in which the tile does not have a data capacity corresponding to Z data or color data for a whole number of pixels have data for at least one pixel split across entries to improve packing efficiency. Rendering modes having a number of bits for Z data or color data that does not equal a power of two such as 24 bits, 48 bits, and 96 bits, may be implemented with a high packing efficiency in tile formats having a data capacity corresponding to a power of 2 bits.

    摘要: A computer system includes an integrated graphics subsystem and a graphics connector for attaching either an auxiliary graphics subsystem or a loopback card. A first bus connection communicates data from the computer system to the integrated graphics subsystem. With a loopback card in place, data travels from the integrated graphics subsystem back to the computer system via a second bus connection. When the auxiliary graphics subsystem is attached, the integrated graphics subsystem operates in a data forwarding mode. Data is communicated to the integrated graphics subsystem via the first bus connection. The integrated graphics subsystem then forwards data to the auxiliary graphics subsystem. A portion of the second bus connection communicates data from the auxiliary graphics subsystem back to the computer system. The auxiliary graphics subsystem communicates display information back to the integrated graphics subsystem, where it is used to control a display device.

    摘要: A method for delayed frame buffer merging. The method includes accessing a polygon that relates to a group of pixels stored at a memory location, wherein each of the pixels has an existing color. A determination is made as to which of the pixels are covered by the polygon, wherein each pixel includes a plurality of samples. A coverage mask is generated corresponding the samples that are covered by the polygon. The group of pixels is updated by storing the coverage mask and a color of the polygon in the memory location. At a subsequent time, the group of pixels is merged into a frame buffer.

    摘要: A system, method and computer program product are provided for performing depth testing and blending operations in a first mode and a second mode. In the first mode, a circuit processes a first number (m) of first pixels per clock cycle, each of the first pixels including both color values and depth values. In the second mode, the circuit processes a second number (n) of second pixels per clock cycle. Each of the second pixels includes the depth values and not the color values. Further, the second number (n) is greater than the first number (m).
