(pest) dulapbot: (asciilifeform) 2020-12-04 asciilifeform: qonfluent: actually, the ~only~ si i'd consider making, is a large homogeneous fpga . but afaik it is ~impossible to actually finance such a project , unless yer already rockefeller.
(pest) dulapbot: (asciilifeform) 2020-08-20 asciilifeform: there is presently no 100%-documented homogeneous fpga on market. and, for fundamental reasons, aint likely to be, 100% of fpga vendors live from the 'rent out the right to use our built-in NIC' and similar scamola
(asciilifeform) bonechewer: still costs less than building one's own fab to create homogeneous sea-of-LUTs FPGA
(asciilifeform) asciilifeform: i.e. even adequately reversed xilinx turd aint a substitute for the missing 'soup of LUTs' large homogeneous fpga.

(asciilifeform) asciilifeform: ftr what asciilifeform was interested in fabbing, was simply a homogeneous-fabric fpga, scaled-up version of e.g. classic ice40 .
(trilema) asciilifeform: ( my current understanding, is that it would be actually ~cheaper~ to bake own homogeneous-fpga thing ... )
(trilema) asciilifeform: erry type of homogeneous fpga worx on same principle. you have cell, in the cell, a shift register. for simplest example take 17 bits. (will be clear why shortly)
(trilema) asciilifeform: not wholly unrelatedly, asciilifeform's semi-automated archaeology birthed a logworthy output recently. seems like in '80s there was an outfit, 'algotronix', that xilinx bought an' killed , to bury the product in patent liquishit. had entirely homogeneous fpga , made from identical ~200-transistor cells ( with simple north-south-east-west tile interconnects, and 1 flipflop inside, configged via 16bit shift register per cell, connecte
(trilema) asciilifeform: http://btcbase.org/log/2019-03-10#1901148 << imho the ( ~homogeneous~ variant of ) fpga is actually the correct model. i.e. you get to stitch it later into however many parallel mechanisms you happen to need on a given occasion.
(trilema) a111: Logged on 2018-05-17 18:54 asciilifeform: mircea_popescu: if we had any fab capacity to speak of, these'd be the priority items : 1) large homogeneous fpga 2) otp roms 3) 1+2
(trilema) asciilifeform: aaaand 1) nobody makes larger homogeneous fpga 2) is likely to ever ; see thread http://btcbase.org/log/2018-01-11#1769061 .
