... or mid-late '70s and early '80s CPUs,
to be more specific. Can anyone
furnish me with a better knowledge as to which processors of that kind of time
period had hardware multiplication and division support?
Integer or floating-point? x86 had hardware floating-point divide/multiply fairly
early with the
80x87 FPU chips (8087, 80287, 80387, 80487, then 486DX2 had the FPU on
the CPU, IIRC).
True. I think the 486DX (minus the 2) had the FP ops built in (did the
386DX??) If I remember right a few manufacturers made math chips for the x86 line.
The 68K line of processors also had companion FPU
chips until they got
an FPU implemented on-chip.
I always forget how darn *old* the humble 68k is :-)
