Does intel in it's current generation of processors provide any Direct Memory Access(DMA) controllers? If yes is it built into the chip? http://en.wikipedia.org/wiki/Direct_memory_access

DMA is pretty much a standard in modern chipsets. Usually it is a seperate module in the southbridge of the motherboard and not actually a part of the CPU chip itself. Modern Intel Processors such as the Sandy Bridge Line should support the technology but it is more a question of the motherboard than the CPU.

So will it be possible for the user to program the triggering of DMA controller to perform tasks such as fetching data,while CPU is busy with other tasks? For example during the video encoding process while processor core is working with a macroblock can DMA controller be used to fetch the next macroblock in parallel? –  eeuser Jun 21 '12 at 4:53
    
That is beyond my knowledge. –  Brandon Kreisel Jun 21 '12 at 12:47
