Programmable network protocol handler architecture

An architecture that achieves high speed performance in a network protocol handler combines parallelism and pipelining in multiple programmable processors, along with specialized front-end logic at the network interface that handles time critical protocol operations. The multiple processors are interconnected via a high-speed interconnect, using a multi-token counter protocol for data transmission between processors and between processors and memory. Each processor's memory is globally accessible by other processors, and memory synchronization operations are used to obviate the need for “spin-locks”. Each processor has multiple threads, each capable of fully executing programs. Each processor contains embedded dynamic random access memory (DRAM). Threads within a processor are assigned the processing of various protocol functions in a parallel / pipelined fashion. Data frame processing is done by one or more of the threads to identify related frames. Related frames are dispatched to the same thread so as to minimize the overhead associated with memory accesses and general protocol processing. The high-speed protocol handler may also provide built-in monitors for examining the activity of its hardware resources and reallocating the workload to the resources that are not heavily used, thus balancing the resource utilization and increasing the workload throughput.
