Network Packager
Problem
There is an Ethernet card that lacks checksum calculation and you are required to add this functionality. The Ethernet card is to get 4 bits at a time from the CPU and collect until it has 16 bits. Then it adds the 4, 4 bit numbers and uses the lower four bits for checksum, thus making a total of 20 bits. It then sends one bit with every clock cycle until the buffer is empty. During transmission it does not receive new data from the CPU.
Input
Clock Pulse CP
Input Available IA
Data D0 D3
Output
Output Available OA
Output Data OD
