EDIT** I split the skeleton circuit photo into 2 because it was unreadable.
All the information below is background information to help in whatever way possible. I was able to map out the truth table and it is CORRECT, now I just need help building the circuit (the last photo is of the given skeleton file).
The way I had originally completed it was horrifically wrong. (Again, the truth table is correct, verified by the instructor) I am just not implementing it properly!
Proper help will recieve a thumbs up :D
What to turn in quz is due a particular data. Goals 1. To practice implernenting a finite state machine controller. 2. To undestand the basies of how data moves in a processor. The Assignment Start from the following files that provide a partial implementation of elC-3 that you will camplete.

Testing instruction fetch and NOT instruction: .ORIG x0000 NOT R2, R1 .END First, notice that I'm using x0000 instead of the usual x3000 for the .ORIG. This is because it's not easy to load the program in a location other than x0000 in the eLC-3. Let's assemble this into a format that Logisim can understand. Use the following command (you may need to adapt it to your environment): cs270/1c3tools/lc3as-hextest.asm&sedi"1s/.*/v.0raw/"test.hex This generates the following file, test. hex: v2.raw947f your program. that is not 0 so that it actually branches. You may also want to change the value of R1 so that you can check that R2 eventually becomes R1. completed and check that the registers end up with the right values. You can always check the value present on a wire by clicking on it with the hand tool. Now that you read the entire document, you may panic at will. :-) Submitting the Assignment When finished, submit your eLC-3. circ file to the ELC3 box in the Checkin tab. ELC3 will be worth 120 points and counted as an assignment. eLC-3 CONTROLLER In ma What to turn in quz is due a particular data. Goals 1.
