DMA means that hardware accesses memory without the help of a CPU.

The alternative is PIO where the CPU fetches the data from memory and 
stores it in the registers, a good example of this is the Atari 2600.

The Atari 2600 doesn't use DMA, so as the 6507 is running the game code 
it has to load the graphics data and store it in the output shift registers.

Two CPU's accessing the same memory is not DMA.
