CS 352 Lecture 24 – Memory and Branching

Dear students, Sometimes in the middle of a semester, we forget why we are here. Let’s step back a moment and check out what the ACM/IEEE Computer Science 2013 Curriculum has to say about computer architecture. Are we hitting upon any of the expected ideas? Let’s then write some programs that will grow our understanding […]

CS 145 Lecture 23 – Images Cont’d

Dear students, I believe the ideas of computer science are best illustrated by manipulating digital media. To me, digital media presents a perfect context: it is one you are familiar with, and it is one that has real-world relevance. I’m sorry if you were hoping to work more with text and numbers. For those of […]

CS 352 Lecture 23 – Hello ARM, For Real

Dear students, Let’s have a look at some ARM instructions. We’ll start with the simplest ones: add a, b, c // a = b + c sub a, b, c // a = b – c Identifiers a, b, and c are just placeholders, not legal operands. In their place, we can either have registers […]

CS 145 Lab 8 – Spinner

Welcome to lab 8! If you have checkpoints from the last lab to show your instructor or TA, do so immediately. No credit will be given if you have not already completed the work, nor will credit be given after the first 10 minutes of this lab. You must work with a partner that you […]

CS 491 Meeting 8

Dear students, We are in the working phase of developing our games, so most of our time will be spent giving weekly progress reports. Here are some questions we will probably ask you: What’s the riskiest part left to investigate in your endeavor? What three or more specific things will you accomplish before we meet […]

CS 145 Lecture 22 – Images

Dear students, We start today by revisiting memory tracing, but this time in programs with loops. Here we go! Memory Tracing #1 public static String trace1(char c, int n) { String s = ""; for (int i = 0; i < n; ++i) { s += c; } return s; } public static void main(String[] […]

CS 352 Lecture 22 – Hello, ARM

Dear students, I want to take a few minutes to explore the next homework assignment, which was inspired by the game Human Resource Machine. But let’s do that at the end of class, rather than the beginning. At this point in the semester, we leave our textbook behind and jump into an industry-grade architecture: ARM. […]

CS 145 Lecture 21 – Loops Cont’d

Dear students, Let’s start with a little Program This: Write a method indexOf that accepts a String and a char as parameters. Without using the builtin String.indexOf method, it returns the index at which the given character resides in the String. If no such character can be found, return -1. Then, let’s seem some more […]

CS 145 Lab 7 – Loops

Welcome to lab 7! If you have checkpoints from the last lab to show your instructor or TA, do so immediately. No credit will be given if you have not already completed the work, nor will credit be given after the first 10 minutes of this lab. You must work with a partner that you […]
