摘要： The invention provides a decoder of symbols of received data, the data being encoded according to a convolutional encoding scheme and transmitted through a communications channel. The data is punctuated according to a puncturing matrix, and has a plurality of state values which describe a sequence of state transitions. The decoder has a generation unit that accepts the received data for calculating metrics of the transitions thereof. A selector responsive to the generation unit selects a path of transitions corresponding to the path produced by a transmitter of the data stream. A traceback unit maintains historical information representative of sequential decision operations of the selector. A counter is provided for counting illegal state transitions of the path selected by the selector, and a control unit, responsive to the counter, determines a puncture rate and adjusts a puncture phase of the received data. The decoder can be used in a VLSI receiver circuit which is adapted to the reception of QPSK modulated data.

摘要： A multi-standard video decompression apparatus has a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine. Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and data in token format. A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens pertinent to that stage and for passing unrecognized control tokens along the pipeline. Reconfiguration processing circuits are positioned in selected stages and are responsive to a recognized control token for reconfiguring such stage to handle an identified DATA Token. A wide variety of unique supporting subsystem circuitry and processing techniques are disclosed for implementing the system.

摘要： Data is transmitted from a sending processor over a network to one or more receiving processor in a forward direction during an allocated slot, and acknowledge signals are sent in a reverse direction during the same allocated slot, to indicate whether the receiving processor is able to receive data If one or more of the receiving processors indicates that it is unable to receive the data, the data is retransmitted during the next allocated slot. This means that the sending processor is able to determine within the slot period whether a retransmission is necessary, but that the slot period only needs to be long enough for one-way communication.
摘要翻译：在所分配的时隙期间，数据从发送处理器通过网络传送到一个或多个接收处理器，并且在相同的分配时隙期间以相反的方向发送确认信号，以指示接收处理器是否能够接收数据如果一个或多个接收处理器指示它不能接收数据，则在下一个分配的时隙期间重传该数据。这意味着发送处理器能够在时隙周期内确定是否需要重传，但是时隙周期只需要足够长以进行单向通信。

摘要： A memory interface for connecting a bus to memory comprises an input, a buffer, an address input, a generator, and a writer. The input receives a plurality of data words from the bus. The buffer buffers the data words received from the bus. The address input receives from the bus addresses associated with the plurality of data words. The generator generates a series of addresses in the memory into which the buffered data words may be written. The series of addresses are derived from the received addresses. The writer writes the buffered data words into the memory at the generated addresses.

摘要： A pipeline structure processes data in a series of stages, each of which has a data input latch (LDIN) and passes it on to the next stage in the pipeline via a data output latch (LDOUT). The stages are preferably connected to two non-overlapping clock phases (PH0, PH1) Adjacent stages are also connected via a validation line (IN.sub.-- VALID, OUT.sub.-- VALID) and an acceptance line (IN.sub.-- ACCEPT, OUT.sub.-- ACCEPT), and in some embodiments also via an extension bit line (IN.sub.-- EXTN, OUT.sub.-- EXTN). Input data is transferred from any stage to the following device on every complete period of both clock signals only if both the validation and acceptance signals in the respective latch are in an affirmative state, whereby data is transferred between stages regardless of the state of the validation and acceptance signals in other stages. A two-wire interface is thus formed between the stages. Address decoding circuitry may also be included in any of the stages so that a stage manipulates the input data stream only when one or more current data words have a predetermined bit pattern. The extension bit line conveys an extension bit that separates fields of different data blocks in the data stream. The invention also includes a method for uniquely encoding data blocks so that only intended pipeline stages are activated, with others simply passing input data through.
