Abstract

A method and apparatus for processing data packets through direct memory access (DMA) in transferring data packets between a bus and an apparatus containing DMA engines. The DMA engines process different contexts, also referred to as distinct logical data streams. The phase of a bus along with the status of DMA transactions are monitored. The phase and the status are used to dynamically allocate priorities to the DMA engines to maximize the efficiency in processing data.
