Hexadecimal Multiplier

346

05:32:41

The multiplier is ready for input when the green LED is on. Enter the operands with a group of 4 push buttons. Click the button on the right to get the result.

This circuit also demonstrates problems related to a) delay in carry signal propagation and b) asynchronous reset :D To see this, run  F x F = E1 calculation a few times and observe the scope. 

There is the 2nd version which is free of these problems: http://everycircuit.com/circuit/5151469049741312

How do you use it?, to me I seem like all your doing is just turning on 7-segment displays showing 0.

Max, there are 4 push buttons, use them to enter the operands, and next push the single button close to them to start calculation.
