[Amforth-devel] Floating point - f* f/ in asm

[pito <pi...@vo...>]

Hi Leon, 
I am preparing two words - f/ and f* in asm. The results from
simulator are:
f_mul  190cycles, 7.6us @25MHz
f_div  735cycles, 29.4us @25MHz. 
You may add a few usec for an overhead. The mul and div routines
works.
The words has been compiled with amforth already, however I still
have problem with passing from/to stack so I cannot get the right
results on stack (could be other problem too), therefore I've asked
Marcin to help a little bit, when possible. 
The routine is using 9 registers (except R24, R25, and YL YH), all
the tempx regs and few stack positions. The words are only ~350
bytes big. Pito
