ah yes, I stand corrected the 1064 was the vanilla IEEE P754 64-bit pipeline and the 1067 added Intel bus interface

at Weitek, we built the 1167 at about the same time as the 80287, we lined up compiler guys such as Green Hills to support our alternative coprocessor ASM (the instruction bus was memory mapped in the 80286 address space IIRC) … several fol

I recall that most Tory voters in the 1980s were "sold" on the idea of privatisation (and had real horror stories in relation to eg phone line installation delays). One of the ideas was to widen share ownership to the average blok

I hate how the UK sewage system has failed. I agree that a good share of the blame lies with the for profit asset stripping owners. But just blaming 1980s Thatcher privatisation lets the government off the hook. The regulators (Ofwat and th

I fancy making a custom ARM or RISC-V chip design, is AI any good for that?

we visited old friends a couple of years ago (we lived in SF in the late 80s) … knowing the city quite well we decided to take BART from SFO downtown. our first notable experience of the decline was a drug user injecting on the BART station

ok … thanks - i’m really hoping that I can delete PowerPoint though since it makes all my app appreciation nerves shudder

Nice idea … did they consider warping the map, I wonder. Not sure why parks in London rank an E or F on the “daily life” scale

It’s fascinating to read all the tech feedback in the comments here, but I think this business is failing because it has yet to achieve true product market fit. Any half decent product, with a nice website, a real solution and some SEO can

as a test of the proposition that human oriented software languages are redundant, I asked my favourite agent to rewrite some code in asm … and yes, it ran and it was fast conclusion… well, it’s scary but actually I think it’s a bit useless

Well even in deep pipelined FPUs (I'm thinking Weitek 1167 for example), the "divide" instruction is microcoded ... this chip had a full IEEE P764 64-bit single cycle barrel shifting MAC ... but divide was built via a special

wonders how ARM did that - the MIPS R2000 came in at ~115k and the 80286 ~134k anyway - say you want 50% of the transistors for on chip RAM these days, then thats 100 billion / 50 thousand = 2 million ARM 1s clocking at say 3GHz 6e15 M

interesting to be reminded that an 8080 (8 bit datapath) took 4,800 transistors an Apple M5 Max is 100,000,000,000 transistors (ok it’s 18 CPU + 40 GPU cores) by comparison so 17 million 8080 equivalents
