DMA design

Hi,
am looking at designing a BUS system for a generic DSP architecture, (SoC/ASIC type) but just the digital side, no analog blocks. Have never done anyhting like this before. Obviously i would like to provide some sort of DMA block but have no idea how these things work, other than a vague oultine (am fresh out of uni). Can anyone point me in the right direction for getting advice on DMA. basics to advanced, for example between the RAM of say a DSP core and other on chip memories.
thanking you in advance.
P

Hi

Look at the old 8237A datasheet. It's an old DMA controler from Intel used in legacy PC.

The datasheet is available at :
