Abstract

See full text

An expanded direct memory access processor has ports which may be divided into two sections. The first is an application specific design referred to as the application unit, or application unit. Between the application unit and the expanded direct memory access processor hub is a second module, known as the hub interface unit hub interface unit which serves several functions. It provides buffering for read and write data, it prioritizes read and write commands from the source and destination pipelines such that the port sees a single interface with both access types consolidated and finally, it acts to decouple the port interface clock domain from the core processor clock domain through synchronization.
