Motivation
Design flow

• Software defined radio (SDR) platforms enable
  dynamic, reconfigurable radio systems.
• SDR waveform implementations combine a variety of
  hardware (analog, ASIC, FPGA) and software (DSP
  and CPU) components.
• Radio design should remain stable, but
  implementations may evolve quickly.
• Move system flexibility from run-time to design
  time.

Design once, use many.
Approach
Impact

• Utilize the Rosetta system level design language
  to capture design intent and system constraints.
• Translate Rosetta specifications to a functional
  intermediate language.
• Utilize non-functional specifications to drive
  system partitioning and synthesis.
• Perform rule-based optimizations as
  source-to-source transformations on intermediate
  language.
• Generate fabric-specific synthesis artifacts.

• Retargetable designs allow implementations to
  utilize newer and more efficient technologies,
  reducing the radios computational and power
  load.
• Intermediate form simplifies source-to-source
  optimizations and target-specific optimizations,
  statically reducing flexibility overhead.
• Prototype toolset demonstrates the synthesis of
  both software (C) and hardware (FPGA)
  implementations from a common intermediate
  source.
