Am I understand correctly? Currently
process = (clk : ondemand(sig));
acts the same as
process = control(sig,clk);
right?
-------------------------------------------------------------------------------
and it seems it has the same problem:
clk = ffunction(int clk(), "","");
sig = ffunction(float sig(), "","");
process = (clk : ondemand(sig));
compiles to
virtual void compute (int count, FAUSTFLOAT** input, FAUSTFLOAT**
output) {
//zone1
//zone2
float fTemp0 = fTempPerm0;
//zone2b
//zone3
FAUSTFLOAT* output0 = output[0];
//LoopGraphScalar
for (int i=0; i<count; i++) {
if (clk()) {
fTemp0 = sig();
}
output0[i] = (FAUSTFLOAT)fTemp0;
}
fTempPerm0 = fTemp0;
}
and this looks correct. However,
process = (clk : ondemand(sig)), sig;
results in
virtual void compute (int count, FAUSTFLOAT** input, FAUSTFLOAT**
output) {
//zone1
//zone2
//zone2b
//zone3
FAUSTFLOAT* output0 = output[0];
FAUSTFLOAT* output1 = output[1];
//LoopGraphScalar
for (int i=0; i<count; i++) {
float fTemp0 = sig();
output0[i] = (FAUSTFLOAT)fTemp0;
output1[i] = (FAUSTFLOAT)fTemp0;
}
}
and this doesn't look right...
Thanks!
Oleg.
