Grading Update: Homework and final averages available. Course grades will be available tomorrow morning. (That's right, I can't decide.) The top three averages are definitely A's, the averages from rank 12 to 16 are C's. To find your average (and rank) click here. I realize that for some of you waiting is difficult; please understand that it's important that this decision isn't rushed. In the mean time, our jury of internationally recognized pseudonymists have come to a decision! After a weekend of sometimes heated deliberation they have decided that the best alias award should go to “Keep the cache or RISC it all?” This could be the slogan of the first Tera MTA machines which did not have caches but instead relied on massive multithreading to cover memory latency. Second place goes to “Strange Quark”, reminding us that physicists are second-to-none in coining names. Congratulations to the winners. |

As curious as I am about everyone's performance on the final (and hopeful of good grades!) I have to have dinner with a faculty candidate, and so grading will not start until tomorrow morning (and will be interrupted by interviews and a seminar which everyone can attend) and so the first grading update will not be issued until about 16:00 tomorrow. Good luck on any remaining finals! |

Office hours this week will be 8:00-9:00 and 14:00-16:00. I'll try to be around those hours but students are welcome to stop by any time to ask a question. |

Study recommendation: look at the solution to the Homework 7 problem 3. There is an interesting difference between the POWER4 and PPC970 global predictor and gshare. It's not something trivial like the size of the table or the length of the GHR, nor is it that the PHT entry is 1 bit (rather than 2 bits), because that was the answer for the bimodal predictor. Think about it then have a look at the solution. |

Please check this page daily for late-breaking study hints, materials, etc. Linked Midterm Exam Solution to the Homework & Exams page. So far only six students have submitted evaluations. More than that will have to respond for each student to receive a full-color, near-pocket-size, New Orleans visitor's guide. (For those who might be shy, I will not be able to read the evaluations until after grades are assigned.) |

Linked Homework 6 to the Homework & Exams page (previously it was only linked to the What's New list). The assignment includes a reading so you might want to get started on it early. (Access is free within lsu.edu, elsewhere use the user name ee4720 and the password given in class.) You are not expected to understand the entire article, in particular the material on caches has not yet been covered and details of how the dynamic scheduling works are missing. Added ISA manuals for the PowerPC to the references page. These are not needed for Homework 6 or earlier assignments. |

Grading Update 2: Problem 2 graded. There was one or two perfect scores. Most answered that for Format R one would just live with a 2-bit sa field. Take a look at some examples of sll and think about a better solution, one with no compromise on the ISA but a possible slight increase in implementation cost. The next grading update will be posted by 20:00 tonight. If the department's 13:30 “long” faculty meeting turns out to be three times longer than our usual “short” faculty meetings then grades may not be available until tomorrow. |

29 March 2004, 18:47:31 CST
Grading Update 1: Problem 1 graded. No one had a perfect answer but some came close. The part that no one did perfectly was the correct size for the load and store instructions. Remember that loads and stores are aligned and that both the load and store addresses can be determined from the problem. Also, look carefully at the loaded value. (The solution will be given in class on Wednesday, but figuring it out in the mean time would be so much more satisfying.) The next grading update will be about 12:00 tomorrow. |

Midterm grades posted to PAWS. The midterm grade is based on the higher homework grade. To get an A you needed a 10, otherwise anything higher than a 6.5 earns a B and any evidence of having shown up earns a C. Don't take the midterm grades seriously, few A's were given to avoid complacency and few C's were given to avoid discouragement. |

Homework submission note: The TA bot will search for a file with the correct name in the correct directory and if one is not found it will try other names and directories. However, it will only consider files with the correct extension, .s, so if the file has a name like myhomework2 or hw2.s.doc it will be ignored by the TA bot. If you are not sure whether your homework was copied check your class account E-mail. If your solution was not copied then email it to me ASAP. |

A line was omitted from the homework assignment viewed by two people, possibly at the chemestry department and in the dorms. If that's you and you copied the assignment add the following line to the second paragraph of the problem 1 description: “The number of spaces before the \n is the digit value.” |

There was a problem with the account setup that would result in the comments in the homework assignment appearing black instead of red. It would also not be possible to run the assignment. If the accoutn was set up after about 12:05 on Tuesday that problem should not occur. Otherwise add the line below to your ".emacs" file (in your home directory) or get another copy of the .emacs from /home/classes/ee4720/com/lisp/.emacs. (eval-after-load "asm-mode" '(require 'asm-class "asm-class.el" t)) After the line is entered or the file is copied, restart Emacs. If that doesn't work please let me know. |
