Checksum and CRC offload
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
Inline IPv4, TCP and UDP checksum generation and verification plus CRC32C for storage protocols.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
