Single socket TCP client

RTL implementation of a single socket TCP module prioritizing low latency, build for the NASDAQ HFT FPGA project.

Requirements

Because I am targetting a specific workload and because I wish to ultimatly push down lantency in part by limiting the total logic depth, this implementation will not feature all TCP features.

Assumptions :

• I can send an ack faster than I can receive new packets

• No out of order packets

• Remote server address and port will never change

• No packet segmentation

Module list

• tcp_entry.v : manages a single socket per entry module
