    This is code used for an some register sharing technique for a low power vlsi design btw

    I am not sure what par > means ?

    does the while statement do all the following statements ?

    ie: receive data, multiply them, and send them to channel z ?


    [chan is for channel]


    also what does putint do ?

    ...... stdout, 10,0, x.

    this outputs 10,0, and the contents of x ?

    ................................................................................

    this is not home work or anything by the way, its interview preparation.

    thank you.

    Wild guess: par is running two threads in parallel?

    So in the first example, thread 1 loops continually receiving pairs of integers off channel i, calculating z = x squared - y squared, and putting z on channel ch

    Meanwhile thread 2 keeps pulling stuff off channel ch and sending it to channel o.


    Example 2, put 10 to channel ch, and in parallel read this and assign it to x.
