DSP IP enables energy-efficient HiFi audio in the car
Where a few years ago a plain car radio graced the dashboard, today increasingly elaborate infotainment systems are emblazoned. Drivers and passengers have increasingly high expectations of the acoustic quality inside the cars. This is where Dolby Atmos for cars comes in: this surround sound technology enables reproduction with more audio detail, clarity and sound definition than previous systems.
To make these sound experiences possible, you need appropriate equipment. The Tensilica HiFI DSP, a digital signal processor from electronic design tool provider Cadence, now supports Dolby Atmos – as the first DSP Core, Cadence points out. The company has optimised Dolby Car Experience technology to run on the Tensilica HiFi DSP and enable appropriate audio playback. By porting Dolby Atmos to the high-performance, low-power Tensilica HiFi DSP, system-on-chip (SoC) vendors can provide automotive OEMs and Tier 1 suppliers with a more energy-efficient implementation without compromising the audio experience.
“Tensilica HiFi DSP is one of the most widely used audio DSPs on the market. HiFi DSPs have been licensed by 19 of the top 20 semiconductor companies to date, with more than 1.5 billion HiFi DSP cores shipped per year. Working with Dolby, we have brought Dolby technology to billions of consumer products over the years, including the very first Dolby Atmos TV,” said Yipeng Liu, group director of marketing, audio/voice IP at Cadence. “Deploying Dolby Car Experience technology on Tensilica HiFi DSPs enables our customers to bring Dolby Atmos to market for cars with extremely high performance, energy efficiency and value.”
