[Discuss-gnuradio] crude compiler for WaveData

[Larry Doolittle]

Guys -

I took a first stab at an FX2 WaveData compiler, since I don't touch
Microsoft-only software (GPIFTool) with a 3.048 meter pole.  This attempt
is good enough to recreate the WaveData definition in usrp1_gpif.c from
the following "source code":

-- cut here --

// GPIF Ctrl Outputs
CTL 0    = WEN#     CMOS 0
CTL 1    = REN#     CMOS 0
CTL 2    = OE#      CMOS 0
CTL 3    = CLRST    CMOS 0
CTL 4    = unused   CMOS 0
CTL 5    = BOGUS    CMOS 0

// GPIF Rdy Inputs
RDY0     = EF#   // hello world
RDY1     = FF#
RDY2     = unused
RDY3     = unused
RDY4     = unused
RDY5     = TCXpire
//FIFOFlag = FIFOFlag
//IntReady = IntReady

Waveform 0: singlerd
 state 0:  ;  wait 1
 state 1:  ;  wait 1
 state 2:  ;  wait 1
 state 3:  ;  wait 1
 state 4:  ;  wait 1
 state 5:  ;  wait 1
 state 6:  ;  wait 1

Waveform 1: singlewr
 state 0:  sgl  activate ;  wait 1
 state 1:  WEN# activate ;  if (EF#) then idle else idle
 state 2:  WEN# activate ;  wait 1
 state 3:  WEN# activate ;  wait 1
 state 4:  WEN# activate ;  wait 1
 state 5:  WEN# activate ;  wait 1
 state 6:  WEN# activate ;  wait 1

Waveform 2: FIFORd
 state 0:  REN# OE#      ;  wait 1 
 state 1:  OE# activate  ;  if (TCXpire) then 2 else 1
 state 2:  OE#           ;  wait 1
 state 3:                ;  if (TCXpire) then idle else idle

Waveform 3: FIFOWr
 state 0:           ;  wait 1
 state 1:  activate ;  if (TCXpire) then idle else 1
 state 2:  activate ;  wait 1
 state 3:  activate ;  wait 1
 state 4:  activate ;  wait 1
 state 5:  activate ;  wait 1
 state 6:  activate ;  wait 1

-- cut here --

Additional status:
  Totally ignores flowstate.
  Sets "state 7" bytes to zero.
  Need suggestions for handling FIFOFlag, TCXpire, IntReady, and non-CMOS CTLs.
  Documentation is nonexistent.
  Tested on debian sarge/sid, perl v5.8.4.

Tiny tarball attached.  Comments appreciated.
