Abstract: A technique implements a novel high-speed high-density packet buffer utilizing a combination of high-speed and low-speed memory devices. The novel packet buffer is organized as a plurality of FIFO queues where each FIFO queue is associated with a particular input or output line. Each queue comprises a high-speed cache portion that resides in high-speed memory and a low-speed high-density portion that resides in low-speed high-density memory. The high-speed cache portion contains FIFO data that contains head and/or tail associated with the novel FIFO queue. The low-speed high-density portion contains FIFO data that is not contained in the high-speed cache portion.

Abstract: 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.
