The DesignWare® Smart Data Fusion IP Subsystem is a complete, pre-verified, hardware and software solution optimized for a wide range of ultra-low power IoT applications. It is designed for fast and easy integration within a larger system context.

The fully configurable Smart Data Fusion IP Subsystem includes the choice of a low gate count and energy-efficient DesignWare ARC® EM5D, EM7D, EM9D or EM11D processor for both RISC and DSP processing, accompanied by an extensive collection of I/O functions and fast math (trigonometric) accelerators. The software libraries of the subsystem contain small-footprint drivers for all I/O, plus DSP functions supporting signal processing. The integrated solution is optimized for "always on" data fusion combining sensor, voice, gesture and basic audio processing typically implemented in IoT edge devices.
