heh! - I'm a Kiwi who lived and worked in Silicon Valley for 20 years, moved back when the kids started high school, but mostly still work there - while I was there I started a company using "Taniwha" ... great for a logo, bu

It was more than simple synthesisable verilog, but not a lot - it was also a compiler rather than an interpreter - at the time VCS was just starting to be a thing, verilog as a language was not at all well defined (lots of assumptions about

At the moment I'm just starting working my way up the hierarchy of benchmarks, dhrystone's been useful though it's nearing the end of its use - I build the big FPGA version (on an AWS FPGA instance) to give me a place to run
844.

It's likely too big for those programs - I am (just now) starting a build with the Open Lane/Sky tools not with the intent of actually taping out but more to squeeze the architectural timing (above the slow FPGA I've been usi

I think they're great - I earned my VLSI chops building stuff in the 90s and I can write Verilog about as fast as I can think so it's my goto language. I've also written a couple of compilers over the years so I know it real

These days there are few caches that need to be flushed at context switch time - RISCV's ASIDs mean that you don't need to flush the TLBs (mostly) when you contect switch. VRoom! largely has physically tagged caches so they don&#x

Well (author here) - this is a private project - typically such a project would be very propriety - people don't get to show their work. But I'm looking to find someone to build this thing, it's been a while since I last buil

I think that we need lots of trace before we decide which ops make sense to combine

Dhystone's just a place to start, it helps me make quick tweaks, and I'm at that stage of the process - it's particularly good because it's somewhat at odds with my big wide decoders - VRoom! can decode bundles of up to

As mentioned here I expect that reality will intrude and the pipe will get bigger - of course good a BTC (and spending lots of gates on it) is important because that's what mitigates that deep pipe. I haven't published my latest

Yes - my point though is that usage of the American billion has taken over in the English speaking world largely because there is seldom a need for something the size of the English (or European ) one (except maybe for the American defence

by Taniwha 5y ago
"billion" meaning 10^12 was the norm in the English speaking world outside of the US up until the 80s/90s - I think that, at least for money, the American billion gets used, while the English billion wasn't very useful

I don't know what happens in the microsoft world, but here in unix-land we learned to address this issue way back when types started to work seriously in C (like the mid 1980s) we put a declaration of "do_stuff()" in a common

Way back then there were competing visions of what the internet might be - some were corporate (and somewhat based around corporate lock-in) DNA/BNA/SNA/etc others were more com ing from a postal/telegraph sort of world

Not my point - Chinese mask manufacturers had an existing market to fill, they already new how to make them, all they had to do was to scale their manufacture which the govt helped them do because they knew it was important - not so much in

Yes, but here in NZ heavy but most;y short lockdowns, and more importantly border closures have given us the time to get our vax rates into the 90%+ double vaxxed level - it means that Omicron is now zooming through, but our death rate from

No - if we see you maskless in an establishment we go somewhere else with sensible customers

But masks were commonly worn in public in Asia by people with a cold or flu before covid - they already had a market for masks before the pandemic and manufacturers filling it

Not really a new thing though, before (very roughly) 1900 most people in France did not speak French as we know it today, the French govt as a matter of policy forced everyone to speak the same language (and it's mostly worked). Here i

Right, I think it's OK as written, I'm just encouraging people to make general specs rather than ones with special cases that are important for one end but slow everything else down

It's worth noting that on systems with real cache coherency (MOESI for example) where for example writing data into the dcache to an address A results in cache line shootdown in the icache as part of fetching an 'exclusive/mo
