Abstract
An integrated circuit comprises co-processor circuitry and a core processor. The co-processor circuitry comprises context buffers and data buffers. The co-processor circuitry receives and stores one of the communication packets in one of the data buffers. The co-processor circuitry correlates the one communication packet with one of a plurality of channel descriptors. The co-processor circuitry associates the one data buffer with one of the context buffers holding the one channel descriptor to maintain the correlation between the one communication packet and the one channel descriptor. The co-processor circuitry prevents multiple valid copies of the one channel descriptor from existing in the context buffers. In some examples of the invention, this is accomplished by tracking a number of the data buffers associated with the one context buffer. The core processor executes a packet processing software application that directs the processor to process the one communication packet in the one data buffer based on the one channel descriptor in the one context buffer.
