Overview
Versatile, Ultra-Low-Power DSP for Audio, Voice, Vision, AI
HiFi 1s provides three benefits. First, it supports auto-vectorization by compiler to eliminate the need for hand-optimization, and thereby opening 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 TTM. 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.
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. 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
