5. RAMP: Research Accelerator for Multiple Processors Goal:Invent an infrastructure for cycle- accurate emulators many-core systems using FPGAs Not goals: FPGA computing, gate-level sim Reasons Rapid design space exploration Scalability High confidence on results Early platform for software development

6. RAMP - Phase 1 The base board: BEE2 The tools: Verilog, RDL, Bluespec The designs: Red, Blue, White Successes Working designs, 2 well attended tutorials, growing team, industrial involvement, … Lessons learned Requirements for new board (BEE3) Advantages and limitations of approaches Prototypes, emulation, co-emulation, … Need for sharing at higher levels Above RTL in a HW-independent manner

7. This Retreat: Start RAMP Phase 2 The base board: BEE3 Discussion on (Common) targets & tools Infrastructure for sharing Dissemination outside of the core team …

8. Retreat Etiquette Actively participate in the discussion Lots of scheduled discussion time & breaks Tell us your opinion & ask questions Be open to research ideas Ignore web/email for 1.5 days
