You will learn common technical specifications. Technical Specifications. As mentioned this version of this course will focus on more practical benefits than previous versions.. Rather than presenting a long list of hardware specifications and how things work for it’s own sake, the focus will be on providing some of the information you will see when actually buying a machine.. Finishing up power issues and how those issues have led us to multi-core processors.. Introduce multi-processor systems.. Stuff upcoming soon. 3/24: HW4 due. 3/26: MS2 due. 3/28: MS2 meetings (sign up posted on 3/24). 2. Processor development till 2004. Out-of-order. Instruction scheduling. 3. Why multi-core ?.
