Does anyone know of other ASICs ? For instance, what's to stop someone creating an ASIC USB drive similar to the Block Erupter but for Photoshop ? Is that sort of application feasible ?
Actually there are USB devices sold that will accelerate hardware video compression.
I've got one of those
Elgato Tubo.264 HD, and they're pretty sweet. We routinely convert large ProRes 422 files into 5Mbps 720p for youtube, and it does it in almost real-time. My 8-core FX CPU is almost as fast, but not quite.
