Flow Control Algorithm

The NoC has to have some sort of synchronisation mechanism to data transverse though.

Example: Buffered Flow Control Handshake Validation [Preferable]

On noc_common.h, line 40, this memory_size was used in the old code to setup the the mips' memory size, which isn' t necessary in this version, as the memory is been build by another group.

The NoC NIs will have a back-end scheme to connect the PE to the routers.

This scheme will be connected to the front-end (wrapper).

Arbiter Algorithm

The Router has to have an arbiter algorithm which is capable of decide which flit has to be sent first given a conflict.

Possibilities are: RR (Round Robin) and FCFS (First Come First Serve) [Preferable]

Fix the data transmission scheme in router channels.

Data can come and go at the same time in the routers.

Even though it was pushed to the master, it's necessary to test if the communication between the routers are being correctly done.

Routing Algorithm

The router has to have a routing algorithm to decide the path which a flit has to follow to go from the source router to the destination router.

Example: XY routing algorithm [Preferable].

When the NoC has a width of one, the connections between the rows are always horizontal.

Include the bibliography used in the project .

Also, document the basic structure.

The NoC will use a Virtual Channel scheme to transmit the flits.

Currently a message can only have a single packet.

Refactor the routing algorithm and NoC Structure to a message with multiple packets.

The Flit should also carry information for debug purposes in simulation time.

Members of the Flit:

• Flit data

• Flit id on simulation

• Flit id on packet

This component will be used as wrapper to connect the diverse PE to the NoC.

This scheme will be developed by the other groups.

The Receiver and Sender are mixed up.

1. Generate simple documentation about the interface used by the PE modules (shell and kernel) with a example as reference to the other groups. (22/06)
