NDP250

Neural Decision Processor

Always-on Vision, Audio, & ASR Processor

Product Brief • Data Sheet • Press Release

The Syntiant® NDP250 Neural Decision Processor™ is a special-purpose chip for edge-AI processing in battery powered devices and other power constrained systems. Target applications include vision, audio, Automatic Speech Recognition (ASR), and Text-To-Speech (TTS) processing. Built using the Syntiant Core 3™ programmable deep learning architecture, NDP250 is designed to natively run multiple Deep Neural Networks (DNN) on a variety of architectures. The NDP250 delivers a 5x increase in ML performance compared to the previous Syntiant Core 2™ NDP120 and NDP200 devices. A programmable Hifi3 DSP is available for feature extraction and signal processing. The integrated power management (PMU) allows single power rail operation. Combined with the integrated PLL this provides further systems cost reduction opportunities.

The NDP250 supports dozens of application-defined imaging, speech, audio, and sensor behaviors for a variety of use cases including:
