Re: [Amforth-devel] benchmarks ;=)

[<joe...@t-...>]

Hi Matthias,

what is your proposal to generate a (1/100us) clock (for e.g. the output
of a bit pattern ) in amforth? (as you wrote, the timer int. isn't
usable for such speed) 
What speed can I expect when I use the word pause? Is there a guarantee
how often the word
is called per ms? Because the pulses should come in a certain time
distance.

Best regards
joh
