I'm building a binary calculator which needs to compare,add,subtract,multiply and divide two 4-bit binary inputs. The output is displayed on two seven-segment display. i must use only basic logic gates, full adder, multiplexer, decoder,demultiplexer. I'm not allowed to use latches or flip-flops.
I have a 7-bit output from the multiplication process. My problem is how to convert the 7-bit binary to an 8-bit code. the first 4-bit for the 1st digit and the other 4-bit for the 2nd digit of the display.
And I also need a schematics on how to Divide a 4 bit binary.
Tnx!!!
