Emulator vs simulator performance

So I think a 170 to 340 times faster emulation is fast enough. This is a benchmark list from 2011 comparing the emulation on different host systems comparing to the real machine:

Code:


Emu42 benchmark results using Erik Ehrling's
"Miller-Rabin Primality Test for the HP-42S"

Prime number: 999,999,999,961

I agree with you, the improved speed vs the original is an important benefit, but not the unique goal of an emulator.
Thanks for the benchmark, I remember it now.

Quote:So I think it's quite hard to compare Emu42 with Free42. Use the one which is more suitable for your problem.

Well , not so hard to compare, since I did it :-) but yes I understand what you mean. My goal was just to have a more clear view of the performance difference. We can't expect an emulator to compete with native applications.

I'm using both Emu42 and Free42, for different usages, as I'm using your Emu71 for Windows in some cases (very precise emulation) and my Emu71/DOS for others (integrated HP-IL environment)
