74LS Datasheet(PDF) – Fairchild Semiconductor

Machine code is fetched from memory and the instructions described are executed by the processor. For each question below, we suggest that you do the work by hand and check it with an assembler.

To familiarize yourself with the microcontroller assembly instructions and the process of assembly.

For ddatasheet lab, you will write a program that uses a loop to add the numbers 1 through and displays the results. Paste a copy of the lab portion of the Lab Writeup Checklist dataheet your hand-in materials. Please see the course web page for due dates. For the questions in part B. For this lab, you will adapt the string hash program from lab 1. You do not have to use the assembly program or the simulator.

It is easy to make small mistakes when you are in a hurry.

Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. 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.

Put a brief comment at the beginning datasheett describes the overall function of the code. For the questions involving the running sum, you may find it faster datashert compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively.

18-348 Lab #2

Assume that all setup, hold, pulse duration, and propagation times darasheet valid and the outputs have settled for these sample points. Do this by hand using the reference materials.

Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence.

This lab uses the same circuit as Lab 2 part A. It is OK to use CodeWarrior to check your work and make corrections after dqtasheet have done it by hand.

Briefly comment each line to describe what it does 10 words or fewer per line. Be sure to consult the Lab Writeup Checklist for both the prelab and lab writeup! 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. Note that 74LS labeling of “Q” dztasheet is in terms of bus bits and not per data sheet for this diagram.

Limit your answer to 40 words. This lab uses a flip-flop to hold a data value on a bar graph LED. Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.

You will connect the circuit and dqtasheet a simple program to verify its operation.

Assume the voltage drop across the LED is 1. You MUST follow these procedures or we will not accept your submissions. The term counter limit refers to the maximum value the counter runs to e. Assume that the output voltage is quiescent i. All non-code parts of the hand-in should be submitted as a single document. For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code.

And, as always, you must do the pre-labs independently. This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another.

Embedded Hardware – Part B: To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. BUT, we expect both of you to understand and datashet in the execution of both labs. Code files should be submitted separately, per the lab FAQ. Paste a copy of the pre-lab portion of the Lab Dagasheet Checklist into your hand-in materials.
