Sure -- http://www.technologyreview.com/energy/20246/ http://www.technologyreview.com/energy/20246/. Specifically, they have "implemented filter primitives using PCMOS technology, used to realize the H.264 decoding algorithm." (from http://www.cs.rice.edu/~lc6/visen/2006vlsisoc.pdf http://www.cs.rice.edu/~lc6/visen/2006vlsisoc.pdf). That paper does not go into much detail about the video implementation, but it seems they discussed it more in a conference presentation. The relevant part of the technology review article: "That changed in 2006. [Palem] and his students simulated a PCMOS circuit that would be part of a chip for processing video, such as streaming video in a cell phone, and compared it with the performance of existing chips. They presented the work at a technical conference, and in a show of hands, much of the audience couldn't discern any difference in picture quality."
