ARC IoT Communications IP Subsystem

The DesignWare® ARC® IoT Communications Subsystem is an efficient NB-IoT modem solution that incorporates an ultra-low power ARC EM11D Processor, hardware accelerators, integrated peripherals and NB-IoT application software to provide a complete software-defined modem that quickly adapts to continuously evolving standards.

Key Hardware Features
  • Configurable ARC EM11D Processor
  • ARC Processor EXtension (APEX) accelerators for Viterbi and Trigonometry
  • Generic digital front-end interface (RF Transceiver via partner)
  • AHB infrastructure and peripherals
  • Power management
Key Software Features
  • Software library supporting base NB-IoT functions such as interpolation, FFTs, and modulation
  • Application examples highlighting typical OFDM processing use cases
  • Low level drivers for DFE, Host IF, USIM, and UART
  • Optional: Full Rel13/14 stack including PHY/L2/L3 layers

The IoT Communications Subsystem is supported by the ARC MetaWare Development Toolkit, which includes a rich library of DSP functions, allowing software engineers to rapidly implement algorithms from standard DSP building blocks.
