Tensilica HiFi 1 DSP

Overview

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

The Cadence® Tensilica® HiFi 1 DSP is the smallest and lowest power member of the HiFi DSP family, developed for battery-constrained applications, such as mobile, hearables, wearables, laptop, automotive, and IoT. Its small area reduces SoC cost. It accelerates artificial intelligence (AI) functions with neural network (NN)-specific ISA and architectural features. It is ideally suited for always-on use cases with sensor fusion or voice/face trigger, along with running codecs and DSP/AI algorithms for pre-processing and post-processing.

Key Features

Always on architecture: Cycle and energy efficient for Bluetooth and Bluetooth Low Energy (BLE) codecs for speech and music
Efficient neural network acceleration ISA and architecture support
Efficient fixed-point DSP operations
Optional vector floating point unit for easy "MATLAB to Optimized DSP" porting
Synthesizable over wide frequency range enabling dynamic voltage-frequency scaling (DVFS) for optimal energy/performance operations
