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

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.

Small Battery-Efficient DSP for Always-On Audio, Vision, and AI/ML

• AI acceleration with 8 8x8 and 8x16 MACs and dedicated ISA
• Imaging ISA and 8 8-bit (and 8x16) MACs for lightweight vision applications
• Double-precision acceleration hardware for audio and vision math functions
• Auto-vectorization support for porting efficiency and fast TTM

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
