摘要： A synchronization and control system for an arrayed processing engine of an intermediate network station comprises sequencing circuitry that controls the processing engine. The processing engine generally includes a plurality of processing element stages arrayed as parallel pipelines. The control system further includes an input header buffer (IHB) and an output header buffer (OHB), the latter comprising circuitry for receiving current transient data processed by the pipelines and for decoding control signals to determine a destination for the processed data. One destination is a feedback path that couples the OHB to the IHB and returns the processed data to the IHB for immediate loading into an available pipeline.

摘要： A programmable processing engine processes transient data within an intermediate network station of a computer network. The engine comprises an array of processing elements symmetrically arrayed as rows and columns, and embedded between input and output buffer units with a plurality of interfaces from the array to an external memory. The external memory stores non-transient data organized within data structures, such as forwarding and routing tables, for use in processing the transient data. Each processing element contains an instruction memory that allows programming of the array to process the transient data as processing element stages of baseline or extended pipelines operating in parallel.

摘要： 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.

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.
