- Test 2 consists of three parts (worth 15 points each): Timers and Interrupts, Concurrency and Semaphores, and AVR Assembly Language. Questions similar to Test 1. No definition or long answer questions. I want to know if you can understand and apply the various algorithms.
- Piezo speaker output for “Hello World” (About as good as it gets on the piezo)
- Demonstrations for Assignment 3a will be Friday, 1st April 2016
- Test 2 will be held on Wed. 6th April 2016 in Machray Hall 315
- Class on Monday, 28th March 2016: the TA will cover three exercises for ASM to C translation, I will be back on Tue.
- Assignment 3b is available now.
- Deadline for Assignment 3a extended until Monday, 21st March 2016 at 23:59
- Assignment 3 is released now.
- Deadline for Assignment 2 extended until Monday, 7th March 2016 at 23:59
- Updated version of Cooperative OS for AVR Butterfly
- Deadline for Assignment 2 extended until Friday, 4th March 2016 at 14:30
- Comments about Midterm Test
- Topics: Everything discussed in class
- Most questions focus on algorithms and datastructures. You need to implement several programs in C for the AVR Butterfly. For analysis style questions, I think of Input $I, Algorithm/Datastructure $A, and Output $O as 3 parameters of the system. I often give two and ask you for the third. Simplest case is: What is the output of algorithm $A/trace the execution of algorithm $A, given input $I? But I can also ask: Here is the output $O of algorithm $A, what was the input $I? Or here is $I and $O, what parameters were used for $A?
- No long answer questions
- There are 3 questions on the midterm, grouped into three sections.
- Late submission policy for Sound and Co-operative OS Assignment updated.
- You are allowed to create one cheat sheet for yourself and use during the midterm: (a) maximum size is US letter sized, (b) you can write on both sides of the cheat sheet.
- Old exams added
- Class on Friday, 26th February 2016 is cancelled
- TA will do demo for Assignment 1 and will cover Pitfalls in Using setjmp
- Fixed error in COM1A should be 10, not 01 in sound lecture notes and added sample program
- Test 1: Wednesday, Feb. 24th 2016 at 14:30 in Machray Hall 315
- Demonstration of Tea Timer, Monday, Feb. 22nd 2016 at 14:30 in E2-438
- Tea timer assignment is now available
