    • An instruction decode mechanism enables an instruction to control data flow bypassing hardware within a pipelined processor of a programmable processing engine. The control mechanism is defined by an instruction set of the processor as a unique register decode value that specifies either source operand bypassing (via a source bypass operand) or result bypassing (via a result bypass operand) from a previous instruction executing in pipeline stages of the processor. The source bypass operand allows source operand data to be shared among the parallel execution units of the pipelined processor, whereas the result bypass operand explicitly controls data flow within a pipeline of the processor through the use of result bypassing hardware of the processor. The instruction decode control mechanism essentially allows an instruction to directly identify a pipeline stage register for use as its source operand.
    • 指令解码机制使得能够控制在可编程处理引擎的流水线处理器内绕过硬件的数据流的指令。 控制机制由处理器的指令集定义为唯一的寄存器解码值,其指定源操作数旁路(经由源旁路操作数)或结果绕过(通过结果旁路操作数)从前一条指令执行的流水线阶段 处理器。 源旁路操作数允许在流水线处理器的并行执行单元之间共享源操作数数据,而结果旁路操作数通过使用结果绕过处理器的硬件来明确地控制处理器流水线内的数据流。 指令解码控制机制基本上允许指令直接识别流水线级寄存器以用作其源操作数。

    • A processor complex architecture facilitates accurate passing of transient data among processor complex stages of a pipelined processing engine. The processor complex comprises a central processing unit (CPU) coupled to an instruction memory and a pair of context data memory structures via a memory manager circuit. The context memories store transient “context” data for processing by the CPU in accordance with instructions stored in the instruction memory. The architecture further comprises data mover circuitry that cooperates with the context memories and memory manager to provide a technique for efficiently passing data among the stages in a manner that maintains data coherency in the processing engine. An aspect of the architecture is the ability of the CPU to operate on the transient data substantially simultaneously with the passing of that data by the data mover.
    • 处理器复杂架构有助于在流水线处理引擎的处理器复杂级之间准确地传递瞬态数据。 处理器复合体包括经由存储器管理器电路耦合到指令存储器和一对上下文数据存储器结构的中央处理单元(CPU)。 上下文存储器存储瞬时“上下文”数据,以便CPU根据存储在指令存储器中的指令进行处理。 该架构还包括与上下文存储器和存储器管理器配合的数据移动器电路,以提供一种用于以维持处理引擎中的数据一致性的方式在各个级之间高效地传送数据的技术。 该体系结构的一个方面是CPU能够在数据移动器通过该数据时同时对瞬态数据进行操作。

    • The invention provides a method and system for switching in networks responsive to message flow patterns. A message “flow” is defined to comprise a set of packets to be transmitted between a particular source and a particular destination. When routers in a network identify a new message flow, they determine the proper processing for packets in that message flow and cache that information for that message flow. Thereafter, when routers in a network identify a packet which is part of that message flow, they process that packet according to the proper processing for packets in that message flow. The proper processing may include a determination of a destination port for routing those packets and a determination of whether access control permits routing those packets to their indicated destination.
    • 本发明提供一种响应消息流模式切换网络的方法和系统。 消息“流”被定义为包括要在特定源和特定目的地之间传送的一组分组。 当网络中的路由器识别新的消息流时,它们确定该消息流中的数据包的适当处理,并缓存该消息流的信息。 此后,当网络中的路由器识别作为该消息流的一部分的分组时,它们根据该消息流中的分组的适当处理来处理该分组。 适当的处理可以包括确定用于路由那些分组的目的地端口以及确定访问控制是否允许将这些分组路由到其指示的目的地。
