The enhanced direct memory access module, also called EDMA, performs high-performance data transfers between two slave points, memories and peripheral devices without microprocessor unit (MPU) or digital signal processor (DSP) support during transfer. EDMA transfer is programmed through a logical EDMA channel, which allows the transfer to be optimally tailored to the requirements of the application.
The EDMA can also perform transfers between external memories and between device subsystems internal memories, with some performance loss caused by resource sharing between the read and write ports.
