Well, maybe it doesn't. I'm just a software person.
Earlier discussions had talked about using a TI 34076 RAMDAC coupled with
a NSC LM1882 video sync generator plus VRAM and interface circuitry to
generate video. The TVP3020 hype said:
By integrating the functions of a traditional color palette, plus
several discrete chips such as buffer logic and multiplexers, the
TVP3020 offers a complete graphics back-end system on a chip which
can directly interface to 4 mega bytes of video random access
memory (VRAM) as well as many industry-standard graphics
accelerators.
I took them at their word (foolish me?). I thought that the TVP3020
would eliminate the all the other gook, plus it has a 64-bit wide
interface which I thought the R4200 had also (possibly eliminating
bus-width matching circuitry).
So, educate me. If this is *not* what the TVP is, then what is it?
