CS 441/641 Spring 2016

Announcements

  • Course grades are posted, and details are on NetRun.  This was a fun class-thank you for taking it!
  • The take-home Final Exam is due Friday, May 6 on Blackboard  (log in first).
    • Clarification on question 2.b: "to reach 50% of peak bandwidth", latency constitutes half the total time to send the message.
  • Project 2 final drafts are due Friday, May 6 on Blackboard (log in first).
    • The final exam time, Friday May 6 from 8-10am, will be a project work session--I'll be there if you need help finalizing your project.
  • Project 2 presentations are April 26 & 28. 
  • HW3, on network communication, is due Thursday, April 14 on NetRun.
  • Project 1 final drafts were due Tuesday, March 22 on Blackboard (log in first).  From the requirements:
    • The final code should be fully debugged, polished, tuned, commented, and include at least a short README explaining what it is, and what its results mean.  You'll be graded on a combination of ambition, correctness, completeness, and comments/style.  Style and clean code count! 
  • The take-home midterm exam is due back Friday, March 11 on Blackboard (log in first).
  • Project 1 presentations were March 8 & 10 in class.
  • Project 1 rough drafts are due by the end of the day Thursday, February 25 on Blackboard  (log in first).
  • HW2 grades and comments are on NetRun
  • HW2 was due by the end of Tuesday, February 23 on Blackboard (log in first).  
  • You should pick a project 1 topic and describe it in class on Tuesday, February 9.
  • The syllabus is now complete with your chosen topics.
  • HW1 grades and comments are on NetRun.  I really liked the CPU designs you came up with!
  • HW1, due by the end of Tuesday, January 26, is to design a simple instruction set, and build and test the corresponding CPU circuit in logisim.  Your CPU should:
    1. Have more than 1 register.
    2. Have registers capable of storing numbers up to at least 15.
    3. Be able to load constants into registers.
    4. Be able to do arithmetic between registers.
    5. Have a conditional jump instruction.
    6. Have a stored program that uses a loop to add up the numbers from 0 to 5, inclusive.
    7. SAVE early and often.  Turn in your working "CPU.circ" file, and a screenshot named "CPU.png" of the CPU having successfully finished the loop and computed 15, on Blackboard (log in first).
  • HW0 grades and comments are on NetRun.  I'm happy to say everybody knows the prerequisites well!
  • New classroom: Chapman 104, with space for everybody!  (Thanks to CS 202, who will be in the CS lab now.)
  • Please take the student interest survey (anonymous, 1 page, 5 minutes) to help me pick course topics you'll be interested in.
  • HW0 has 2 questions.  Turn in your resulting files by the end of the day on Tuesday, January 19 on Blackboard (log in first).
    1. Use Logisim to draw a circuit diagram for the boolean expression OR(AND(A,B),AND(NOT(A),XOR(C,D))).  Save your .circ file as "1.circ", and give me a screenshot named "1.png".   List all the values of A, B, C, and D that will make this expression evaluate to true, in a plain text file named "1.txt".  (Clarification: feel free to use logic gates; you can use bare transistors if you think that's easier!)
    2. Use NetRun to write some assembly code (for any machine) that uses a loop to add up the numbers from 0 to 5, inclusive, and returns this sum.  Run the code, and verify the answer is 15.  Copy the code out as a plain text file named "2.asm".
