Abstract
A communication processor that uses a group of hardware buffer descriptors and a virtual array of buffer descriptors to control the communication ports of the communication processor. The virtual array of buffer descriptors is a data structure stored in a local memory that contains data fields that are similar to the hardware buffer descriptors of the communication processor. The processor swaps data between the hardware buffer descriptors and the virtual array of buffer descriptors to provide "just in time" storage of control and status information used by the communication ports to transmit and receive data.
