Tuesday, August 31, 2010 at 2:34PM Last week I chatted with a couple of friends about the x86 clones that appeared in the 1990's. Companies like Rise, Nexgen and Centaur.
When I got back to my desk I recalled that the mid-1990's also had a number of companies building media processors to offload MPEG-1/2/4 video, audio, 2D graphics and even modem codec processing.
Googling reveals a great example. The 1996 Hot Chips 8 presentation by Paul Kalapathy of Chromatic Research which covers the Mpact multimedia processor. A quick skim reveals an architecture that should be familiar to any GPU developer: a sea of general-purpose registers, huge on/off-chip bandwidth and SIMD vector opcodes driving integer ALUs and SFUs. The part reportedly achieved 1 BOPS at 120MHz.
Very impressive and another great spoke on the wheel of reincarnation!
