    may i know how to design 8-bits encoder that link to 7-segment decoder or PIC (need to show the output)?
    how is the circuit or the model look like?
    THANKS

    I think you could use a ROM with 8 address inputs and 14 outputs, seven for each digit.

    Or you could write the boolean equations for each of th eseven segments of each digit and implement it in n FPGA

    Or you could read the 8-bits with a microcontroller and time multiplex the seven segment outputs.

    OR...

    and so forth

    Please re-phrase your question. It makes no sense in its current form.
