Lecture notes are available in postscript , pdf , and powerpoint formats.
Postscript files are good for printing, but pdf files are usually better for viewing on the screen. Pdf files are generally 8-16 times smaller than the postscipt since pdf files don't include any fonts. Every effort will be made to get the notes on the web prior to the lecture. Note, however, that the notes may be updated slightly following the lecture. These 977 slides, which are more than the pages in the textbook Computer Organization and Design, are for your noncommercial use.
