    摘要: An error correction code method comprises examining a validator of one of a plurality of data in a data stream at a first processing stage and directing the one of the plurality of data through at least one subsequent processing stage to a corrected output if the validator indicates an error. The method also includes directing the one of the plurality of data to the corrected output if the validator does not indicate an error.

    摘要: A system and method are provided for directing the flow of data and instructions into at least one functional unit. In one embodiment of a system of components defining a plurality of nodes, a queue network manager (QNM) forming a part of each node, is provided. In this embodiment, the QNM comprises an interface to a network that supports intercommunication among the plurality of nodes, an interface configured to pass messages with a functional unit within the node, a random access memory (RAM) configured to store at least one of a message and a programmable instruction, and logic configured to control an operational aspect of a functional unit based on contents of the programmable instruction.

    摘要: A method and apparatus for implementing a fully associative cache directory that stores X cache tags and responds to N read cache tags simultaneously in a single cache directory access to provide a corresponding cache block index for each of the N read cache tags. The cache directory includes a mini-directory and a main directory. The mini-directory stores M cache tags and corresponding block indexes, wherein M is equal to at least N. The mini-directory is fully associative and simultaneously compares each of the M stored cache tags against each of the N read cache tags. The main directory stores the X cache tags and provides corresponding block indexes. The main directory is fully associative and compares P read cache tags against each of the X cache tags simultaneously, P being less than N. The N read cache tags are initially compared against the mini-directory to provide a block index for each of the N read cache tags that hits in the mini-directory. Only those read cache tags that miss in the mini-directory are compared against the main directory.

    摘要: A method and apparatus for the storage and retrieval of pixel information, including first and second data portions, is shown to include first and second memory devices each having a random access memory and a shift register, wherein the random access memory includes an on screen section and an off screen section. Pixel information is retrieved from the random access memories in response to control signals and transferred to the shift registers. A controller controls the storage and retrieval of the first data portion in the on screen section of the first memory device, controls the storage and retrieval of the second data portion in the off screen section of the second memory device and generates the control signals so that the first and second data portions are outputted from the shift registers simultaneously.
