Overview
Versatile, Ultra-Low-Power DSP for Audio, Voice, Vision, and AI
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.
Key Benefits
Auto-Vectorization, Expanded AI/ML, Versatility with Imaging ISA
Auto-Vectorization
Enables the compiler to automatically vectorize data arrays to utilize the SIMD structure of HiFi 1s DSP, eliminates the need for hand-optimization
Expanded AI and Base Platform Performance
Dedicated MACs and ISA enhancing ML/AI and upgraded base platform to LX8, allowing richer applications to run at ultra-low power levels
Lightweight Imaging and Vision
Imaging targeted ISA and MACs for always-on lightweight vision applications to run standalone or in conjunction with a Vision DSP
Double-Precision Floating-Point
Greatly accelerates double-precision math functions found in audio and voice code, obviating the need to tradeoff precision with range
Features
