Remote profiler functionality #651

Closed drichmond closed 2 years ago

drichmond commented 2 years ago

Added remote store tracking functionality
Added (unconnected) wires to network_tx to track returning store credits
Added print statements to remote_load_trace
Separated remote load bind instantiation from tracer instantiation

Fun trick I like to use:

wire unused = &{returned_credit_v_i, returned_credit_reg_id_i}

tommydcjung commented 2 years ago

What's the reg_id sent by the vanilla core though? sw instruction doesn't have rd field, so I don't think it's possible to track each request uniquely.

drichmond commented 2 years ago

I thought sw uses the reg_id field. I thought black parrot required it.

I've removed the write latency tracking code, and removed the unused signals that I added
