Yes and then the TMS34020 came out which had a trapezoid fill instruction. Essentially you would partition your polygon into trapezoids; For each trapezoid you would load the appropriate registers ... the slopes of the edges used 16.16 fixed point numbers. I remember how much you could do with fixed point arithmetic.. very few programmers even know how program using fixed point anymore. A very useful lost art.

There was also a built in Bressenhsm line drawing instruction.

Then there was the TMS34082 floating point coprocessor. I essentially wrote a primitive OpenGL'ish pipeline API. That was fun.

Wow... I really wish a general purpose processor like this made it into the PC. The best stuff doesn't always win in the marketplace.

Last time I used fixed point arithmetic was for a J2ME game targeted at the Sharp GX20, for a game competition sponsored by Vodafone.
