    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

    Way too little information. Make and model of the network card, how you are using it.

    I buy network cards for $2-10 each. At that price if it doesn't work it isn't worth messing with.
