Overview
Versatile DSP Combining Traditional Signal Processing, Codecs, and AI Functions
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 Benefits
Cycle and Energy Optimized for Target Applications
Sensor Fusion
The HiFi 1 DSP supports sensor fusion concurrent with control and signal processing. It embraces modern algorithms with support for base (light to medium) AI acceleration. Several software partners bring the best sensor fusion software to the HiFi 1 DSP.
Smallest DSP
The Tensilica HiFi 1 DSP for Audio is the smallest of the HiFi DSP family, reducing SoC cost as well as standby/leakage power.
Lowest Energy DSP
The Tensilica HiFi 1 DSP has the lowest energy consumption of the HiFi DSP family.
Always-On, Always-Listening
The Tensilica HiFi 1 DSP is well-suited to voice trigger, face trigger, and sensor fusion functions that need to be always on, while preserving battery.
