Abstract: A shared memory based network having a transferring network switch and a receiving network switch. In this network, each network switch has a stack, queues corresponding to output ports and a dared control port. The stack stores available buffer addresses of the shared memory. Each of the queues stores to-be-accessed buffer addresses of the corresponding output port. The shared control port is driven to indicate states of the shared memory based network, so that th stack of the transferring network switch is identical with the stack of the receiving network switch. The shared memory can be read by all output ports of both the transferring network switch and the receiving network switch according to their corresponding queues.

Abstract: Improved method and apparatus for vector quantization (VQ) to build a codebook for the compression of data. The codebook or "tree" is initialized by establishing N initial nodes and creating the remainder of the codebook as a binary codebook. Children entries are split upon determination of various attributes, such as maximum distortion, population, etc. Vectors obtained from the data are associated with the children nodes, and then representative children entries are recalculated. This splitting/reassociation continues iteratively until a difference in error associated with the previous children and current children becomes less than a threshold. This splitting and reassociating process continues until the maximum number of terminal nodes is created in the tree, a total error or distortion threshold has been reached or some other criterion. The data may then be transmitted as a compressed bitstream comprising a codebook and indices referencing the codebook.

Abstract: A signal processing system determines the characteristic of a signal for encoding or decoding by examining and classifying such signal, and then applies a transformation or inverse transformation to such signal. Depending on classification of the signal, various transforms or inverse transforms are applicable adaptively thereto.

Abstract: Decoding and encoding of variable length data words and data strings is accelerated by testing for and processing more than one word or string per encoding or decoding cycle. In an encoding scheme wherein fixed length data words are encoded into variable length data strings, decoding is carried out by first receiving a data stream having a plurality of encoded data strings contained therein, and then testing at least a portion of the data stream to determine whether the portion contains one of a number of selected sets of multiple data strings. If the portion of the data stream contains one of the selected sets of multiple data strings, the multiple data strings are decoded into a corresponding set of multiple data words. This decoding procedure allows a plurality of encoded data strings to be decoded in a single decoding cycle. The procedure may be implemented using either a single lookup table or a set of split-level lookup tables.

Abstract: A display memory architecture which efficiently stores and processes true color and index mode pixels is disclosed.

In addition, consecutive index mode pixels are located in not necessarily consecutive different groups of bit planes in consecutive banks so that a plurality of index mode pixels can be accessed simultaneously in reading and writing operations. Pixel swap circuits are used to swap the order of the R, G and B components of true color pixels and the order of simultaneously accessed index mode pixels, when the order of the accessed locations is different from the order in which R, G and B components of true color pixels or a plurality of index mode pixels are processed by a graphics processor.
