Cadence releases fourth generation Tensilica HiFi DSP architecture

New audio solution implements emerging object-based multi-channel audio standard

On January 6 , 2015 in San Jose, California, USA, Cadence (Cadence Design Systems, Inc.) released the Cadence® Tensilica® HiFi 4 audio / voice digital signal processor (DSP) IP core for system-on-chip, SoC) design is the industry's highest licensable 32-bit audio/ voice processing digital signal processing (DSP) core. The fourth-generation HiFi architecture can implement emerging object-based multi-channel audio standards and provide 2 times the performance of HiFi 3 DSP, making it the ideal solution for DSP-intensive applications such as digital TVs, set-top boxes (STBs), Blu-ray discs and car audio and video entertainment systems. Ideal .

With the rise of object-based audio standards, individual sounds become objects that can be placed anywhere in a room . These sounds can be mixed at any location and can be mixed along the way, not necessarily in a recording studio. Object-based audio systems can calculate the location of sound so that it sounds like it is coming from the same source no matter where the speakers are, providing a more natural surround sound experience that requires a more powerful digital signal. processing power. Now designers only need one core - HiFi 4 DSP , to get such DSP processing capabilities, instead of having to use multiple DSPs before.

Cadence Tensilica HiFi 4 DSP is a highly optimized audio /speech processor used to efficiently execute audio /speech codecs and pre- and post-processing modules as well as other demanding DSP functions in the field of wireless communications. Its main features are :

• Supports four 32x32- bit multiply-accumulators (MACs) per cycle in the form of 72- bit accumulators , giving it additional advantages in computationally intensive functions such as Fast Fourier Transform ( FFT ) and Finite Impulse Response ( FIR ) Audio DSP 2x more performance.

• Under certain conditions, supports 8 32x16-bit MACs per cycle ;

• The four -level very long instruction word ( VLIW ) architecture supports two 64- bit value operations per cycle .

• Provides user-selectable vector floating-point unit , supporting up to 4 IEEE single-precision floating-point MACs (single-precision IEEE floating-point) per cycle

• The software is compatible with existing HiFi DSP series and provides more than 140 HIFI optimized audio/voice codecs and audio enhancement software packages.
