21 Dot operation calculator
21 : Dot operation calculator
- Author: Yannick Reiß
- Description: Can calculate the result for 3 bit multiplication and division.
- GitHub repository
- Clock: 0 Hz
How it works
It takes input 1 to determine operator and two 3 bit inputs as operands. The result is put to output 0-5. In multiplication mode it just outputs the number binary encoded. In division mode the output pins 0-2 are the quotient and 3-5 are the reminder.
How to test
Connect input 1-7 with switches and output 0-6 with leds.
External hardware
7 switches, 6 leds
