Course pages 2011–12
Lectures 1-3: I suggest you read the first Chapter of Hennessy and Patterson. Appendix B. may also be useful (this is Chapter 2 in the 3rd Edition).
Lectures 4-7: Chapter 2 of Hennessy and Patterson. Chapter 3. will probably also be useful.
Lecture 7: Appendex G in Hennessy and Patterson (this is covered in Chapter 4 in the 3rd Edition)
Lecture 8: Finish reading Chapter 3.
Lecture 9 and 10: Appendix C and Chapter 5.
Lecture 11: If you need further explanations read Appendix F (on CD).
Lecture 12 and 13: Chapter 4.
Lecture 14: "Principles and Practices of Interconnection Networks", Dally/Towles is an excellent book if you want to go into more detail or clarify any particular areas.
I have provided additional material for each lecture on the course wiki to help you go beyond the basic material. These papers and reports may clarify elements of the course or simply help you explore aspects that you find particularly interesting. It is certainly not a requirement for you to read and understand the additional material.
