Hi, when running the amforth4.2 in simulator I've observed following: a) "1 1 + ." takes 42sec to calculate b) "1000 1000 3000 + - ." takes 60sec to calculate. Does it mean the amforth spends most of the time with tokens lookup? P. PS: I've spend some time with FlashForth 4.7 (pic24 and dspic33, subroutine threaded) and the mips to mips comparision with the same code (Sieve, the only difference the FF uses "for next" instead of "do loop") shows 8x speed advantage of the FF. |
