Cn language • Similar to standard C • Main difference is poly variables • Example code: #include <stdiop. h> // Output support #include <lib_ext. h> // Extra functions to support features of hardware int main() { poly int n; n = get_penum(); // individual PE number printfp("PE number: %dn", n); // Output different message per PE return 0; } • poly short get_penum(): number of current PE • mono short get_num_pes(): number of PEs on CSX processor 49
