The extra credit HW were basically not that great. Many questions weren't simplistic, and seemed copied from the book or some other books. Some people averaged 3-4 questions, and few were really interesting. Some wrote a lot of questions, but again, not SO interesting. Because of lack of good questions, the HW were weighted rather small.

In hindsight, extra credit HW wasn't as good an idea as I had hoped. Maybe, you felt differently.

I should email out raw projects grades over the weekend, if you're curious about the grades. Recall that projects can only help you one letter grade up, maximum, and for many, it didn't change grades at all.

Also, it should be sll $rd, $rt, shift_amt. Both have been corrected in the project.

Also, I have corrected the syntax for all shift instructions. Thus, srav, srlv and sllv should take the same 3 registers in the same order, and sra, srl and sll should take the same two registers and shift amount in the same order.

I just added sra and srav. You do NOT have to implement if you dont want. If you do, please note it in README. Put it as "EXTRA EXTRA CREDIT" or something since it was added so late.

Goal is to have final grading done by Sunday, and project grading done about midweek. I can give you grade estimates on exams Sunday, but please wait until I post or email before asking about grades. Thank you!

P3 due next Tuesday (July 8). P4 due next Saturday (July 12).

I've also split up the notes on "Implementing Mealy and Moore machines" so that there is now a separate "Excitation Tables for D and T flip flops". The content is basically the same, just been split into two set of notes, instead of one. See Class Notes.

Project 2 postponed until Tuesday evening

I hope to post a "Case Study" on 8-1 MUX implemented out of 2-1 MUX, this weekend. A student asked about it, and it seemed interesting. I may also go ahead add a "Case Study" on 5-1 MUX done in class, too.

The two topics that were on Exam 2 (Spring 2003), that WON'T be on Exam 2 on Monday are:

• CPU diagram (C2)
• Linking object files (C4)

Also, we might do the 6-step detailed fetch, shown in the handout given in class on the quiz tomorrow.

Also, I've fixed up some of the code in the findMin. See Errata.

Also, I've put notes on recursive functions (case study). However, the book also has some discussion on recursive functions.

The tractor-trailer used in the freeway chase scene has "Big Endian Eggs" writtein on its side. This is a reference to Swift's Gulliver's Travels. "The Lilliputians, being very small, had correspondingly small political problems. The Big-Endian and Little-Endian parties debated over whether soft-boiled eggs should be opened at the big end or the little end". ("Big-endian" has also been adopted as computer terminology).
