Multiplication/division time/space cost analysis ?
« on: 16:19, 16 January 13 »
After Kevin's good introduction to multiplication
Kevin's good introduction to multiplication, we can see

Programming:Integer Multiplication - CPCWiki , Programming:Ultrafast Multiplication - CPCWiki
and
Programming:Integer Division - CPCWiki

Prodatron's ultrafast solution is quite wild.
Executioner's solution seems clever, and it looks constant time which is really nice.

Anyone performed some time+size (esp. tables) analysis of the different solutions ?

Has anyone alternatives ?

Had a CPC since 1985, currently software dev professional, including embedded systems.

I made in 2013 the first CPC cross-dev environment that auto-installs C compiler and tools: cpc-dev-tool-chain: a portable toolchain for C/ASM development targetting CPC, later forked into CPCTelera.
