I don't know about all of those pieces of hardware, but I'm sure the nVidia and ATI implementations are simply running on the GPU - I seriously doubt they would devote so much effort and chip area to having a squillion little processing units, and then add separate MPEG-1/2/4 video decoders in hardware as well. So the decoders are still software. And they'd be licensed of course.

Oh, and I can't find anything about this "DECODE264" instruction.

"I seriously doubt they would devote so much effort and chip area to having a squillion little processing units, and then add separate MPEG-1/2/4 video decoders in hardware as well."

Yet they do exactly this. And the main reason is power consumption. Specialized ASICs are still faster even compared to GPGPU.

It was a joke. The latest intel processors already have AESDEC and AESENC so..
