Lecture 6: Static ILP

Lecture 6: Static ILP. Topics: loop analysis, SW pipelining, predication, speculation (Section 2.2, Appendix G) Assignment 2 posted; due in a week. Loop Dependences. If a loop only has dependences within an iteration, the loop

Lecture 12: Advanced Static ILP

Lecture 12: Advanced Static ILP. Topics: parallel loops, software speculation (Sections 4.5-4.10). Predication. A branch within a loop can be problematic to schedule Control dependences are a problem because of the need to re-fetch on a mispredict
