Extra Credit

Extra Credit: is a way to improve your grade by up to a half grade, i.e. up to a maximum of 50 points

Extra Credit is granted for good ideas expressed in class, constructive questions and contributions in class, identifying errors in class material

Volunteers may present their HW 1 solution, or select topics in class, 10 min. each for a few extra credit points

Any error in class material, even the slightest typo –but only pointed out the first time– is worth some extra credit

Presenting smart homework solutions in class can deserves extra credit; you need to volunteer for such presentations proactively

Expected Background

Know how to program in C or C++

Understand Computer architecture elements

Basic CPU operation, microprocessor or other

RISC, CISC, GPR architecture

Data cache and instruction cache

Some branch prediction, and why necessary for pipelined architecture

Read Handout 1

Summer terms are shortSummer terms are short

Plus we lose 1 lecture in week 1

So start reading early

Follow the schedule of papers to be read

And read the on-line information, specifically handout 1 in week 1, and work on homework 1 in week 1

OK to communicate with me, Herb via email from day 1, even though I am in China –or on the road
