1 Jan 07 RAMP PI Report: Plans until next Retreat & Beyond Krste Asanovíc (MIT), Derek Chiou (Texas), James Hoe(CMU), Christos Kozyrakis (Stanford), Shih-Lien Lu (Intel), Mark Oskin (Washington), David Patterson (Berkeley, CO-PI), and John Wawrzynek (Berkeley-PI)

2 Executive Summary RAMP component “API” RAMP-White Demonstration Student Community Team-Building RDL’ization Project (aka RAMP Bootcamp) FCRC Tutorial Plan

3 RAMP Component “API” Position: RAMP’s goal is to provide infrastructure to explore interesting architectures PI’s and students will define an initial set of useful baseline components (specifically their interfaces) Plan  Use RDL as component interface spec language  Derek derive first draft from current RAMP-White  2-day meeting to refine and finalize proposal?  Share component development---rely on each other to complete the whole picture  Setup SVN repository for versioning and archiving  (Question: include reference software models?)

4 RAMP-White Position: RAMP-White demos how to build a system in RAMP, not what to build RAMP-white will use RDL’ized components  Shared-memory MP of Leon cores  Each student will contribute a piece of the finished puzzle  Accurate target time dilation/clock cycle accounting RAMP-white leverages co-simulation technology  simulated I/O subsystem (RDL’ized Simics)  Simics user/control interface E.g., Simics interface to BEE2 boards running 64 Leons; speed of 64 parallel 50 MHz computers with Simics multiprocessor UI (breakpoints, visualization, …)

5 RAMP Student Community Position: RAMP students working together on one project Plan:  Precede future RAMP retreats with separate student-only retreats  Have regular (bi-weekly?) phone conference for design reviews and to coordinate progress  Participate in a RAMP RDL’ization Project bootcamp ASAP (see next slide)

6 RDL’ization Project Position: RAMP-White will use RDL RDL’ization project by RAMP students  A fun-filled 1-week get away at locale TBD  Start with working components from Leon3/GRLIB  Finish with a working RDL’ized Leon3 system  (Get the MP version to work?) Outcomes:  Get to know RDL  Get to know each other  Useful RDL’ized components  Jump start RAMP-White

7 FCRC Tutorial at CS Olympics Announcement (not available) to generate interest in both architecture & programming communities  Thacker talks about M/S plans for making & using RAMP Showcase RAMP’s unique capabilities  Scalability to large MP systems (512 CPU Blue)  Working experimental designs (128 CPU Red T.M.)  DIFT Security testimonial? (HW reduce kernel 40X to 500 LOC  prove kernel correct ) Announce future release plans (boards & gateware) Participants hands on use of RAMP systems 1/2 day Participants get to take home  Xilinx XUP-II board and EDK  A CD of example RAMP systems to build and run on XUP-II  (Question: How to distribute RAMP-Blue Microblaze?)
