Abstract

Disclosed is a circuit that implements the User Datagram Protocol standard (UDP) 16-bit checksum using an 8-bit path and 8-bit adder. This reduces the amount of logic gates necessary to implement the checksum. Because it is implemented directly in the hardware, the circuit takes the processing burden off of software.
