    • Streaming data is processed through one or more pipes of connected modules including mixers and/or splitters. The data is carried in composite physically allocated frames having virtual subframes associated with different ones of the splitters, mixers, and other transform modules. Nesting trees and pipe control tables represent the structure of the pipes. A frame allocator is assigned to a particular module in a pipe. Rather than issuing a control transaction to all modules when any one of them completes an operation upon its source data, a control manager requests a module to begin its operation only when all of its input subframes have become available. Frame control tables record when any module has completed an operation, and a pipe control table lists which modules provide data to which other modules.
    • 流数据通过一个或多个连接的模块管道进行处理,包括混合器和/或分离器。 该数据在具有与分离器,混合器和其他变换模块中的不同分配器相关联的虚拟子帧的复合物理分配帧中承载。 嵌套树木和管道控制表表示管道的结构。 帧分配器被分配给管道中的特定模块。 控制管理器当其任何一个完成其源数据上的操作时,不会向所有模块发出控制事务,而是只有当所有模块的所有输入子帧都可用时才要求模块开始操作。 任何模块完成操作时,帧控制表记录,管道控制表列出哪些模块向其他模块提供数据。

    • A system for the efficient decoding of data encoded with variable length codes uses an N-bit buffer as an index to a data look-up table or other suitable data structure. The encoded data is stored in an encoded data storage area and extracted N bits at a time. The N bits are used as an index or indicator to a location within the data look-up table. The contents of the data look-up table in the indicated location correspond to one or more decoded tokens and also provide an indication of the number of data bits from the N-bit buffer that were used to represent the decoded tokens. A pointer is incremented by the number and indicates a location within the encoded data storage area where the next N bits will be extracted and stored in the buffer. If the N-bit buffer is greater than or equal to the maximal length for the variable codes, at least one valid token is guaranteed as a result of a single data look-up operation. However, a data look-up operation typically results in a plurality of decoded tokens. In one embodiment, the decoding system is used for facsimile operation and may include additional data in the data look-up table to permit rapid decoding of two dimensional facsimile codes.
    • 用于以可变长度代码编码的数据的有效解码的系统使用N位缓冲器作为数据查找表或其他合适的数据结构的索引。 编码数据存储在编码数据存储区域中,并一次提取N位。 N位用作数据查找表中的位置的索引或指示符。 指示位置中的数据查找表的内容对应于一个或多个解码令牌,并且还提供来自用于表示解码令牌的N位缓冲器的数据位数的指示。 指针增加数字,并指示编码数据存储区域内的下一个N位将被提取并存储在缓冲器中的位置。 如果N位缓冲器大于或等于可变代码的最大长度,则由于单个数据查找操作,至少有一个有效令牌得到保证。 然而,数据查找操作通常导致多个解码令牌。 在一个实施例中,解码系统用于传真操作,并且可以在数据查找表中包括附加数据,以允许二维传真码的快速解码。
