Reduced Logic Binary Addition

Reduce the amount of logic required to add by spending extra clock cylces to do it. Use: To utilize this circuit punch in two 4 bit binary values (MSB left). Next, toggle the logic switch under the counter. '0' = load, '1' = add Finally, wait for the answer(4 cycles because 4 bits) Info: Reset will occur automatically when the select logic switch is set to '0' (load). Loading takes 1 rising edge clock. The display will also clear itself given enough time. Sorry about the ridiculous looking design. Oscope: Blue = Clock (rising edge based design) Red = Select ('0' = loading, '1' = adding) Green = Done('0' = not done, '1' = done) If you have any questions regarding the operation or components of this circuit, i will do my best to answer them.
