2 Table of content Model Based Design tool for FPGA Development (MBDK) Model Based Design tool for host development (GNU Radio) PicoSDR : High End MIMO RF frontend for GNU Radio

3 Radio420M

4 Radio420M + Perseus 601x

5 Radio420M + Perseus 601x = PicoSDR

6 WHY do we want a rapid prototyping tool? A - Reusability of existing IP B - Model based design (save up to 60% time) C - Automatic code generation D - Debugging/Simulation capabilities WHAT do we want them to do? 1 - Modeling 2 - Simulation 3 - Compilation 4 - Deployment

7 Rapid prototyping on FPGA with Model Based Design

20 PC/FPGA Mixed Architecture

21 PC/FPGA Mixed Architecture

22 PC/FPGA Mixed Architecture, benefit from the best of two worlds: Target FPGA with MBDK : Computation intensive waveform processing Enable larger bandwidth Processing chain replicated for each channel Latency does not grow with # of channels System Generator algorithms implementations Manage high data rate interfaces to RF front end Low power consumption MIMO radios sold in lower volumes often integrates low power and low cost FPGAs (Artix-7, Zynq, etc)

23 PC/FPGA Mixed Architecture, benefit from the best of two worlds: Target PC with GNU Radio : Software is free, PCs are accessible Start developing quickly Benefit from IP libraries and applicative examples Focus only on developing your algorithm right away Exchanging with world wide developers community Collaborative waveform development For basic applications, don t need to write C code

24 PC/FPGA Mixed Architecture, benefit from the best of two worlds: Benefits from combining the two (PC/FPGA): Ease transition on real fabric (from PC to IC) Move blocks from PC to FPGA as applications grow Benefit from both parallel and sequential computing Migrate PHY algorithms developed on PC to FPGAs Collaborative waveform development Move computation intensive blocks from PC to FPGA Accelerates workflow
