CS 221 / ECE 259 Advanced Computer Architecture II

Spring 2008
Alvin R. Lebeck

This is a tentative schedule, we may deviate. I will attempt to post slides before class for those class with lectures. Most readings are requierd. Italics are optional readings, red are required, others are student presented required. For some links you need to be on a Duke IP address machine (or use the duke VPN client).
