You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. Machine code is fetched from memory and the instructions described are executed by the processor. Code files should be submitted separately, per the lab FAQ.
Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. Confirm the operation using the simulator to make sure you got it right, which you need document only by saying “checked with simulator” in your hand-in.
Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points. You will connect the circuit 74le374 write a simple program to verify its operation. Assume the voltage drop across the LED is 1.
This lab uses a flip-flop to hold a data value on a bar graph Datssheet. Scan the printed-out document after you add the checkmarks and upload 74la374 the hand-in folder. Please see the course web page for due dates.
For example, if Q7 is high, and Q6: Assume that the output voltage is quiescent i. For branch instructions, insert labels at the appropriate locations and use the label values 74ks374 your disassembled assembly code.
Look carefully at the data sheet! Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. And, as always, you must do the pre-labs independently. The first instruction is done as an example. Your program shall meet the following requirements: Think of how embarrassed you will be if you get something wrong after saying you followed the checklist. For this lab, you will write a program that uses 74ls3744 loop to add the numbers 1 through and displays the results.
Do this by hand using the reference materials. Using a checklist is your best defense against this in general, and in particular is extremely helpful for avoiding unnecessary point losses when handing in assignments for this course.

Limit your answer to 40 words. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document. Create a similar example using different, non-trivial e.
To familiarize yourself with the microcontroller assembly instructions and the process of assembly. For this lab, you will adapt the string hash program from lab 1.
This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another.
Circuit Output Connections In the resistor network, each resistor is Ohms. This lab uses the same circuit as Lab 2 part A. For the questions involving the 74ls347 sum, you may find it faster to compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively.
Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. You do not have to datqsheet the assembly program or the simulator.
Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram.

Pin 2 provides D0 to bus, Pin 5 provides D1, etc. For each question below, we suggest that you do the work by hand and check datxsheet with an assembler. When you record your answers, use the conventions described in the discussion section. Also, see the course materials repository page. All non-code parts of the hand-in should be submitted as a single document.
18-348 Lab #2
It is easy to make small mistakes when you are in a hurry. Why is it valid or invalid?
We suggest each of the two students in your lab group be “in charge” of one of the two parts of the lab parts to help divide the work.
