CS 441 Homework 1

Use Logisim, Logisim-Evolution, or another graphical circuit editor to draw a circuit diagram for a programmable CPU.

Your CPU should:

Have more than 1 register.
Have registers capable of storing numbers up to at least 15.
Be able to load constants into registers.
Be able to do arithmetic between registers.
Have a conditional jump instruction.

Write a stored program that uses a loop to add up the numbers from 0 to 5, inclusive.

SAVE early and often! Turn in your working "CPU.circ" file, and a screenshot named "CPU.png" of the CPU having successfully finished the loop and computed 15.

Turn in your circuit and screenshot on Blackboard (log in first).
