- 1 of 10 - Stanford University 10 November 2005 Computer Architecture Comprehensive Exam Solutions Exam Instructions Answer each of the questions included in the exam. Write all of your answers directly on the examination paper, including any work that you wish to be considered for partial credit. The examination is open-book, and you may make use of the text, handouts, your own course notes, and a calculator. You may use a computer of any kind but no network. On equations: Wherever possible, make sure to include the equation, the equation rewritten with the numerical values, and the final solution. Partial credit will be weighted appropriately for each component of the problem, and providing more information improves the likelihood that partial credit can be awarded. On writing code: Unless otherwise stated, you are free to use any of the assembly instructions listed in the Appendix at the back of the book, including pseudoinstructions. You do not need to optimize your MIPS code unless specifically instructed to do so. On time: You will have one hour to complete this exam. Budget your time and try to leave some time at the end to go over your work. The point weightings correspond roughly to the time each problem is expected to take.
