it would be nice to see a microprocessor be cosher, including all the
cell libraries, and surrounding "glue logic" be cosher, including ghdl
(now that's something else we need to invent --- ghdl to replace vhdl
and verilog).

nowadays, many processors are superscalar (also known as "multiple issue",
multiple instruction dispatch, etc..).

the goal of superscalar processors is to *exceed* 1 instruction per clock
cycle.

even the pentium (which doesn't pipeline well to begin with given its
non risc arch., and thus different length per instruction) is superscalar
(actually it's double issue but kind of a crippled version of double issue
given the asymmetry).

it would be nice, however, to see a modern *multiple issue* microprocessor
with a cosher design, and a full disclosure of the internals.

i have a feeling that such a computer architecture could rapidly overtake
pentium, given the tendency of modern engineers to work in a gnu framework.

and then take multiple superscalar microprocessors and make something that's
smp (e.g. running linux smp), or perhaps multiple computers in a beowulf
cluster (like our 64 processor undershirt project).
