chan variable be used in more than two parallel statements i Topic is solved

[Bayanaa]

I have a DJ KIT board. Code is something like  below:

int main(){

streaming chan c_mix_out;

streaming chan c_out;

par

{

 on stdcore[0]:
     {
      func1(c_mix_out);
     }
on stdcore[0]:
     {
      func2(c_mix_out);
     }
 
on stdcore[0]:
     {
      func3(c_mix_out);
     }
}


}

But compiler says that: error: `c_mix_out' used in more than two parallel statements;

So I tried to assign c_mix_out to another variable and wanted to use something like below:

assign c_out  <:  c_mix_out ;

but compiler says: incompatible types in output

Any idea? What I missing?

Channels are used to communicate between two logical cores. You cannot have same channel end connected between more than two logical cores. If you need to communicate inforamtion from a core to more than one logical core, you need to have a seperate channels between each core. You cannot use same chan el to communicate between more than two logical cores because, it violates parallel usage rules. You will find mor einformation about channels in the following : https://www.xmos.com/en/published/how-s ... er-channel
