DMA is used in almost every complex system or subsystems, but it's observed that teams either build the DMA controller from scratch for each project for specific application or take the existing DMAC available from elsewhere. This article discusses the architecture of DMAC that can be used with any kind of Bus, configuration (parallel, serial transfers), can be connected to any kind of ports, most importantly any kind of software assumptions can be implemented in the DMAC very easily.
