Tile-Hub-Tile #46

Closed setat closed 6 years ago

Hi, In which part of the source code, I can find Tile-Hub-Tile process? I mean if source tile and destination tile connect to the same hub, we have tile-hub-tile connection, where can I find this part?

If in hub.cpp, which part of the code exactly?

Hub.cpp......>In this part, line 403: void Hub::tileToAntennaProcess() {.... 403: r_from_tile[i] = route(flit); ...} we can have two answers for route(flit); 1-port number which the destination tile is connected or 2- DIRECTION_WIRELESS we only use DIRECTION_WIRELESS what if we have "port number which the destination tile is connected" as the returned of route(flit)?

In the current routing strategies implemented, you go to wireless direction when destination is connected to a different hub. Otherwise you continue to the next hop using wired. It's like driving by car (wired) and discovering that you have reached an airport that has a direct flight to another airport. Of course, any other strategy could be implemented in noxim by adding some code.
