7 7 - ECpE 583 (Reconfigurable Computing): XPS / MP3 Overview + Midterm Overview Iowa State University (Ames) Initial Project Proposal Slides (5-10 slides) Project team list: Name, Responsibility (who is project leader) –Team size: 3-4 (5 case-by-case) Project idea Motivation (why is this interesting, useful) What will be the end result High-level picture of final product High-level Plan –Break project into mile stones Provide initial schedule: I would initially schedule aggressively to have project complete by Thanksgiving. Issues will pop up to cause the schedule to slip. –System block diagrams –High-level algorithms (if any) –Concerns Implementation Conceptual Research papers related to you project idea

8 8 - ECpE 583 (Reconfigurable Computing): XPS / MP3 Overview + Midterm Overview Iowa State University (Ames) Weekly Project Updates The current state of your project write up –Even in the early stages of the project you should be able to write a rough draft of the Introduction and Motivation section The current state of your Final Presentation –Your Initial Project proposal presentation (Due Wed 10/19). Should make for a starting point for you Final presentation What things are work & not working What roadblocks are you running into

12 12 - ECpE 583 (Reconfigurable Computing): XPS / MP3 Overview + Midterm Overview Iowa State University (Ames) i) What would be 2 disadvantages of using 3-LUTs instead of 6-LUTs in part a)? (2pts) ii) If you had to manufacture an FPGA device to support applications that used MANY 2-to-1 multiplexers, would you make the FPGA primitives 6-LUTs or 3-LUTs. What would be 2 advantages of using your choice compared to the alternative?
