The Synopsys 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.
