Tensilica’s HiFi 3 DSP IP Core Provides Over 1.5x Better Performance for Audio Post Processing and Voice in Smartphones and Home Entertainment

"The HiFi 3 DSP is the natural evolution of our popular HiFi 2 architecture, which is the most popular licensable audio DSP core and has been designed into millions of smartphones, Blu-ray Disc players, digital televisions, cameras, and other devices," stated Larry Przywara, senior director of multimedia marketing. "HiFi 3 was initiated based on smartphone OEM and semiconductor manufacturer needs for better power efficiency of high-performance voice and audio post-processing functions. In particular, the HiFi 3 DSP achieves greater than an 80 percent increase in performance for the FFT (fast Fourier transform), FIR (finite impulse response), and IIR (infinite impulse response) math functions that are essential in audio pre- and post-processing, plus a greater than 1.5x improvement in performance for most voice codecs compared to HiFi EP. This performance boost helps significantly reduce the power consumption requirements for leading edge algorithms."
