[f-cpu] yet another snapsot_jws

[jaap stolk <jwstolk@yahoo.com>]

hi,

not a lot of time since the last update, but
a lot of news:

i implemented (whether used or not) different
latencies for high / low output od the IMUL EU.

it contains an updated pictiure:
/f-cpu/c/fcpusim/fcpusim.png

i added an other bypass, i now heve:

- direct bypass:
  F D X E X R
          |
  . . F D X E X R

- delayed bypass:
  F D X E X R
           \
  . . . F D X E X R

- 2x delayed bypass:
  F D X E X R
           \--\
  . . . . F D X E X R

(after we can use normal register output.)

it contains jwsasm (changed ygasm)

and some example / test programs
(including YG's winograd_DCT )

try:
-unpack it somewhere (no need to install)
-goto: /f-cpu/programs/
-and run runme.sh
(-read: /f-cpu/programs/README.txt )
-run: ./fcpusim winograd_dct.bin

there is sill a lot of wirk to do, but you should now
be able write your own asm programs and run them on
the F-CPU  (using only MOVE ADD SUB and MUL) :-)

(and some things i forgot.)

jaap
