I'm using SDF stars, with multiin and multiout ports. What I want is for
each message on each input port to be copied to each output port. So I'm
doing the following:
------------------------CODE------------------------------------------
setup {
//get total number of messages on all input ports and assign
that number of delays to output ports
PortHole *p;
MPHIter nextp(input);
int totMsg = 0;
while ((p = (SDFPortHole *)nextp++) !=0 ) {
totMsg += p->numXfer();
}
output.setSDFParams(int(totMsg), int(totMsg)-1);
}
go {
PortHole *pin;
MPHIter nexti(input);
Envelope pktIn;
int iout = 0;
//LOOP THROUGH EACH INPUT PORTHOLE
while ((pin = (SDFPortHole*)nexti++) !=0) {
PortHole *pout;
MPHIter nexto(output);
//LOOP THROUGH EACH MESSAGE ON THAT INPUT PORTHOLE
for (int imsg = 0; imsg < pin->numXfer(); imsg++) {
((*pin)%imsg).getMessage(pktIn);
// operate on input message and put in CopiedData;
........
//LOOP THROUGH EACH OUTPUT PORTHOLE AND SEND EACH
MESSAGE
while ((pout = (SDFPortHole *)nexto++) !=0) {
// send modified message to output
Envelope pktOut(*CopiedData);
(*pout)%iout << pktOut;
iout++;
} //while
} //for
} //while
} //go
--------------------END CODE------------------------------------------
If I have 2 input stars, one that is sending 3 messages, and one that is
sending one message, I get the following output:
Star1 message3
Star2 message1
Star1 message2
Star2 message1
Star1 message1
Star2 message1
But I only want to see the one message from Star2 once. So I want the
output to be:
Star1 message3
Star1 message2
Star1 message1
Star2 message1
How can I change the code to achieve this? Maybe I don't understand the
scheduler well enough. Any help would be appreciated.
Thanks
