摘要： 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.

摘要： A display memory architecture which efficiently stores and processes true color and index mode pixels is disclosed. The R, G and B components of true color mode pixels occupy different groups of bit planes in different banks of a frame memory. 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.

摘要： 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. The above procedure may also be applied to an encoding scheme wherein variable length data words are transformed into fixed length encoded data strings to encode the variable length data words. Furthermore, the above procedure may be applied to an encoding scheme wherein variable length data words are transformed into variable length data strings to both encode and decode the variable length data words and data strings.
摘要翻译：可变长度数据字和数据串的解码和编码通过对每个编码或解码周期进行测试和处理多个字或字符串来加速。在将固定长度数据字编码为可变长度数据串的编码方案中，通过首先接收其中包含多个编码数据串的数据流，然后测试数据流的至少一部分来确定该部分是否包含多个选定的多个数据串集合中的一个。如果数据流的部分包含所选择的多个数据串集合中的一个，则将多个数据串解码成相应的多个数据字集合。该解码过程允许在单个解码周期中解码多个编码数据串。该过程可以使用单个查找表或一组拆分级查找表来实现。上述过程也可以应用于其中可变长度数据字被变换成固定长度编码数据串以对可变长度数据字进行编码的编码方案。此外，上述过程可以应用于编码方案，其中可变长度数据字被变换成可变长度数据串，以对可变长度数据字和数据串进行编码和解码。

摘要： 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.

摘要： A host computer, a graphics processor which receives and executes commands generated by the host computer, a display memory for storing display data, and a display device for displaying the display data are provided. A graphics context is also provided in which the parameters of a current image are stored. A processing unit for receiving and executing the graphics commands issued by the host computer and for converting the parameters stored in the graphics context into the display data, and a drawing unit for storing the display data in the display memory are also provided. Furthermore, a shared memory is provided which is directly accessible to the host computer so that it can write the parameters of a next graphics command into the shared memory while the graphics processor is executing a current command. The shared memory is also directly accessible to the graphics processor so that it can receive the parameters of the next graphics command to be executed directly from the shared memory. In a preferred embodiment, transfers of the graphics parameters between the graphics context and the shared memory are accomplished by employing a bit-block transfer method and a mask register stored in the graphics context.
