    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 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： 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.

    摘要翻译： 流水线结构处理一系列级数据，每一级具有数据输入锁存器（LDIN），并通过数据输出锁存器（LDOUT）将其传送到流水线中的下一级。 这些级优选地连接到两个非重叠时钟相位（PH0，PH1）。相邻级还经由验证线（IN-VALID，OUT-VALID）和接受线（IN-ACCEPT，OUT-ACCEPT）连接，以及 在一些实施例中也通过扩展位线（IN-EXTN，OUT-EXTN）。 只有当相应锁存器中的验证和接收信号都处于肯定状态时，输入数据才能从两个时钟信号的每个完​​整周期从任何阶段传输到下一个设备，从而数据在阶段之间传输，而不管验证状态如何 和其他阶段的验收信号。 因此，在两个级之间形成两线接口。 地址解码电路也可以包括在任何一个阶段中，使得仅当一个或多个当前数据字具有预定位模式时，才操纵输入数据流。 扩展位线传送分割数据流中不同数据块的字段的扩展位。 本发明还包括一种用于唯一地编码数据块的方法，使得仅预期的流水线级被激活，其他简单地传递输入数据。
