Versatile, Ultra-Low-Power DSP for Audio, Voice, Vision, and AI

Smallest, ultra-low-energy DSP for always-on sensor fusion, always-listening voice trigger, and Bluetooth/BLE codecs The Cadence®…

Overview

Ultra-low-power always-on audio, voice, imaging, and AI inferencing

The Cadence Tensilica HiFi 1s DSP provides three benefits. First, it supports auto-vectorization by compiler to eliminate the need for hand-optimization, thereby opening it to every embedded programmer. Second, it enhances the always-on AI capability to allow higher-performance ML algorithms to run on an ultra-low power DSP. Third, it adds imaging ISA to support lightweight always-on vision processing.

Auto-vectorization support unburdens the programmer from expert-level hand-optimization, opening the HiFi 1s DSP to a vast pool of non-DSP programmers, lowering development costs, and accelerating time to market. The expanded AI and imaging ISA allow lightweight vision and machine learning applications to run at ultra-low power levels. Double-precision ISA helps modern audio programs run efficiently.
