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

Benefits of PC based Open-Source rapid prototyping tools
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
For basic applications, don’t need to write C code
Nutaq introduces it’s GNU Radio Plug-in
Support for Radio420x based SDR systems, such as

GNU Radio runs on :
An external Host PC, running Linux Ubuntu or Fedora
A PicoSDR2x2-Embedded, it has a QuadCore i7
Embedded PC that can run GNU Radio and Linux in a
small table top form factor
The 3 possible configurations for running with GNU Radio:
PicoSDR2x2 + External Host PC
PicoSDR4x4 + External Host PC
PicoSDR2x2-Embedded

PC/FPGA Mixed Architecture
PicoSDR goes GNU Radio
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)

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
