Are you sure you're not confusing the 34010 with the 32010? The 320x0
series was their DSP line. The 340x0 series (I think there was a
34020 at some point) was definately for graphics. It had all kinds of
special instructions for interpreting memory as chunks of pixels and
had a special video scanout circuitry that you could feed directly to
a DAC for a video signal. The chip had all sorts of registers to
control the scanout timing. I have docs on them somewhere, IIRC.
Talking of DSPs reminded me of the graphics chips
family that TI
created in the mid 80s, the TMS34010 was the first part.
Not really a graphics chip per se, but a general-purpose DSP, though
AFAIK it was primarily laid out for telecom purposes. I may be biased
though, that's where I've seen it used :-) Only marginally. By the time I did actually some code
in telecom
industry (Hello to all ex-Newbridge Ottawa people!) I was working with
the C050 - and even that one was strining under the workload of just a
few channel at 8kHz sampling rate for applications such as G.729
coding or echo cancellation. The C010 in comparison was VERY limited.
OK, you're definately talking about the 320x0 series here and not the
340x0 series!
