I'm not quite sure what you mean - the Burroughs machines have full sets of display registers (hardware managed pointers to each of the stack frames that were currently in scope - Algol/etc had more complex scoping that modern C-s
722.
by Taniwha 4y ago
Burroughs machines have 2 sorts of pointers - effectively pointers to offsets on the stack (indexed by a full display so you can do full algol scope semantics, more than just C) as well as pointers to heap memory (base and bounds, with pagi

most of the Burroughs machines had 2 real top of stack registers (and DP extensions) they were wired to actual lights on the console. Transputers did the fixed small number of top of stack registers thing

so essentially a B5500 and subsequent systems - it had 2 top of stack registers, a hardware stack and mostly 8-bit opcodes (longer ones for constants and addressing) - super CISCy - that made sense in a time where memory access was very exp

not formally, just people working to get stuff done - as a nominal 'logic designer' I've routed my blocks, written scan insertion software, done back end static timing closure etc etc There's just a lot of scope for the

I would take this article with a grain of salt - especially the whole "logic designers do X and then physical designers do Y" bit. My experience doing this has physical designers working on cell libraries in parallel with logic de

also you want to teach: why is iterative factorial faster than recursive? and , why do some (arbitrarily) large recursive factorials crash while the iterative equivalent just takes a long time ? (stack overflow) IMHO we don't teach com

It does kind of depend - I've made a career of being both: being the log designer that understands software (and makes sure the registers make sense etc) and/or the software guy that understands the c hips (and can read the verilo

This didn't last though - with taxation fixed by the elected governments various kings raised taxes by reducing the size of the gallon - this left the wine gallon (the one the US adopted) smaller than other gallons, in the 1800s the UK

No - I think that big-endian only makes sense because you grew up with it. Think about who used numbers back when this decision was made - small business people who mostly did math by hand - addition in particular - which we do from small
