Xlife-8 v5 has been released
« on: 17:13, 11 February 21 »
I have done some optimizations and make the program about 5% faster.
IMHO the Z80 code optimization can continue endlessly. :)
I also got some benchmark results.
BTW Amiga people has Aminet .  Is there something like this for the Amstrad CPC?  Something that keeps all CPC software?
Thank you.

Thanks for the update :)

Sadly, no, there's no such repo unfortunately... perhaps room for a project??

Interesting results, thanks!

Two questions:
- Did the 80286 run with 6 MHz (as indicated) or was it 16 MHz (the usual speed for it)?

- Not a question, but... The ER values... Well, I think due to very different CPU architecture it's hard to dompare. For example: the 6502 is built in a way to do thing on one cycle, where the Z80 uses four cycles for the same thing. This (IMHO) needs to be taken in account. But some hardware guys here may be able to explain this in better words.

Thanks again for the update!  :)


EDIT: Instead of aminet we have cpc-power

Yes, there is MIPS for this
Million of instructions per second
6502 is approx 0.5mips and z80 too

use RASM, the best assembler ever made :p

I will survive

Exactly, MIPS and MHz are four times different.

I just used pce emu which declares that it emulates the original PC AT 6 MHz.  IMHO it is one of the best emulators for the old IBM PC AT.  BTW I don't know the IBM PC which used 16 MHz.  Maybe only some clones in the 90s.
As it is written on the benchmark results page, ER gives you a value which indicates how effectively a processor can convert clock cycles into actions.
Thanks for the mentioning the cpc-power.  Maybe I should try to upload Xlife-8 there.
