As a master student electrical engineering I’ve recently been studying the Fermi architecture a lot. Today I found out that NVIDIA’s PureVideo HD—e.g. h.264 decoding—is also handled by the same chip.
My question now is if anyone here knows if this is accomplished by a separate part of silicon—so dedicated logic—or if this is also handled by the CUDA cores. My best guess would be dedicated logic, since also the low-end Fermi cards can do PureVideo HD. But on the other hand would it maybe be more cost effective to not reserve silicon for this specific application.
Any thoughts on this are more than welcome, even if you can’t give a definite answer to the question.
