QNX has ported its QNX®Acoustics for Active Noise Control (ANC) software to the Cadence® Tensilica® HiFi Audio/Voice digital signal processing (DSP) core. The Tensilica HiFi Audio/Voice DSP from Cadence is available immediately.
QNX Acoustics for ANC is a software solution for reducing unwanted engine noise inside passenger vehicles. It can run on a DSP core in the vehicle’s infotainment system or audio amplifier, eliminating the dedicated hardware of conventional ANC solutions. QNX Acoustics for ANC provides up to 20dB noise power reduction, depending on the transducer and vehicle seating configuration, and can be used with any of Cadence’s HiFi Audio/Voice DSP IP cores.By combining QNX Acoustics for ANC with the widely deployed Cadence Tensilica HiFi Audio/Voice DSP core, system designers can reduce engine noise while also eliminating the costs associated with designing and prototyping a custom hardware controller module.”
“Automotive OEMs and Tier 1 head-unit suppliers can now incorporate QNX Acoustics for ANC with HiFi DSP-based SoCs, providing a quieter and more relaxed driving experience.”– Larry Przywara, Cadence’s group director of audio/voice intellectual property (IP) marketing.
