Found some AMD bitslice stuff you might want to copy

[Randy Dawson]

Hi Dave,

I got hooked on these when they were the new thing to compete against CMOS.

I was working in geophysics, and they were the rage for fast ffts and seismic processing.

Later, had a graphics box called SUPERSET that was a graphics supercomputer (1982) that executed a 48 bit a=b (op) c instruction set in a single cycle.  Sortof like a precursor to the DSP.

All 2901 based, in a microwave oven size box, and wow what a toy.

It was Ian Hirscholn's company, the author of PLOT3D, later bought by SAS.

Fond memories of the old days...

So heck, Im very interested in homebuilt CPUs.  Even to cheat via the FPGA route, or not even get out the wire wrap gun but do it all in modelsim.

I ramble.

Cheers.

Randy
