摘要： 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.
摘要翻译：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。

摘要： A technique is provided for striping packets across pipelines of a processing engine within a network switch. The processing engine comprises a plurality of processors arrayed as pipeline rows and columns embedded between input and output buffers of the engine. Each pipeline row or cluster includes a context memory having a plurality of window buffers of a defined size. Each packet is apportioned into fixed-sized contexts corresponding to the defined window size associated with each buffer of the context memory. The technique includes a mapping mechanism for correlating each context with a relative position within the packet, i.e., the beginning, middle and end contexts of a packet. The mapping mechanism facilitates reassembly of the packet at the output buffer, while obviating any any out-of-order issues involving the particular contexts of a packet.

摘要： A sequence control mechanism enables out-of-order processing of contexts by processors of a symmetric multiprocessor system having a plurality of processors arrayed as a processing engine. The processors of the engine are preferably arrayed as a plurality of rows or clusters embedded between input and output buffers, wherein each cluster of processors is configured to process contexts in a first in, first out (FIFO) synchronization order. However, the sequence control mechanism allows out-of-order context processing among the clusters of processors, while selectively enforcing FIFO synchronization ordering among those clusters on an as needed basis, i.e., for certain contexts. As a result, the control mechanism reduces undesired processing delays among those processors.

摘要： A mechanism synchronizes among processors of a processing engine in an intermediate network station. The processing engine is configured as a systolic array having a plurality of processors arrayed as rows and columns. The mechanism comprises a barrier synchronization mechanism that enables synchronization among processors of a column (i.e., different rows) of the systolic array. That is, the barrier synchronization function allows all participating processors within a column to reach a common point within their instruction code sequences before any of the processors proceed.

摘要： A mechanism synchronizes instruction code executing on a processor of a processing engine in an intermediate network station. The processing engine is configured as a systolic array having a plurality of processors arrayed as rows and columns. The mechanism comprises a boundary (temporal) synchronization mechanism for cycle-based synchronization within a processor of the array.

摘要： An encryption mechanism tightly-couples hardware data encryption functions with software-based protocol decode processing within a pipelined processor of a programmable processing engine. Tight-coupling is achieved by a micro-architecture of the pipelined processor that allows encryption functions to be accessed as a novel encryption execution unit of the processor. Such coupling substantially reduces the latency associated with conventional hardware/software interfaces.

摘要： A processor isolation technique enhances debug capability in a highly integrated multiprocessor circuit containing a programmable arrayed processing engine for efficiently processing transient data within an intermediate network station of a computer network. The technique comprises a mechanism for programming a code entry point for each processor of a processor complex utilizing a register set that is accessible via an out-of-band bus coupled to a remote processor of the engine. The programmable entry point mechanism operates in conjunction with a bypass capability that passes transient data through a processor complex that is not functional, not running or otherwise unable to process data. Another aspect of the debug technique involves the ability to override completion control signals provided by each processor complex in order to advance a pipeline of the processing engine.

摘要： An inter-chip communication (ICC) mechanism enables any processor in a pipelined arrayed processing engine to communicate directly with any other processor of the engine over a low-latency communication path. The ICC mechanism includes a unidirectional control plane path that is separate from a data plane path of the engine and that accommodates control information flow among the processors. The mechanism thus enables inter-processor communication without sending messages over the data plane communication path extending through processors of each pipeline.
