AI and DSP performance leader with up to 4X the NN performance and 2X the DSP performance of the HiFi 4 DSP, ideal for digital as…
Performance leader melding AI/ML, audio/voice, and lightweight vision DSP performance with auto-vectorization for fast time to market
HiFi 5s greatly improves TTM by allowing the compiler to automatically vectorize data processing, eliminating the need for time-consuming hand-optimization, opening up the DSP to every embedded programmer. It brings double-precision MACs and ISA to accelerate modern audio algorithms requiring high range and precision. Lightweight imaging and vision algorithms are accelerated with special ISA.
Auto-vectorization support unburdens the programmer from expert-level hand-optimization, opening up the HiFi 5s DSP to a vast pool of non-DSP programmers, lowering development cost, and accelerating TTM. The expanded ISA and MACs allow modern audio algorithms to run more efficiently OOB by utilizing the added double-precision features and run lightweight vision cases along with audio.

Auto-Vectorization, Double-precision, Versatility with Imaging ISA
Auto-Vectorization
Enables the compiler to automatically vectorize data arrays to utilize the SIMD structure of HiFi 5s. Eliminates the need for hand-optimization
DSP and AI Performance
Highest performing DSP for both AI/ML and DSP processing
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
