asciilifeform: atm we're sorta in those dark age days of 'weitek' maffs coprocessor etc
asciilifeform: phf may find interesting , that this 'macivory' happens to be the one with no weitek. which normally would be a sad, but in my case is gold, from my pov the weitek is just extra crud to emulate
asciilifeform: ^ 26, to be exact, 'ivories' ( the rest weitek and 3620 rubbish )
asciilifeform: i wouldn't consider ever to put floatism in a new design, but for compat with the vintage soft one would need it ( fortunately unlike 'ivory' the weitek is documented to death, i even have a copy of the datashit from ancient ru stash )
asciilifeform: even ivory had a buncha similar ugly, iirc it still used external weitek thing (same as in yours and mine 486) for arithmetics
asciilifeform: mircea_popescu: i've outlined several items, historically. will summarize for the l0gz, in order of descending ( per asciilifeform's lights ) universality : 1) sane fpga 2) sane minimal cpu 3) 8192-bit arithmetizer ( a la ye olde weitek! but for ints ) 4) 2+3 , if somehow can be fit into 1 die 5) 1chip carrierless radio ( per thread ) 6) sane ethernet controller .

asciilifeform: !#s weitek
asciilifeform: and who even knows if weitek is fully documented somewhere.
asciilifeform: re fp, i'll observe that bolix used a weitek fp unit
asciilifeform: but when weitek (original brand of 'fpu') appeared, registers therein were already, iirc, 80 bit
asciilifeform: (floating point was not originally part of intel arch, in case anyone forgot or never owned a 'weitek')
