LAS VEGAS—In the cacophony of CES, it’s refreshing to find an escape. I found mine in a set of headphones slipped over my ears. Standing in the Cadence booth chatting with Yipeng Liu, with Cadence audio product marketing, I’m listening to audio using DTS Headphone:X technology . As Liu said, “hearing is believing.” If you close your eyes, you find yourself in a room with the audio. It’s a strange experience, but an amazing advance in audio processing that’s the latest in a long relationship between DTS and Cadence Tensilica. The DTS algorithm is processed by a Cadence Tensilica HiFi 3 DSP , running—in the case of the demonstration—on a Xilinx FPGA board with two HiFi 3 cores. The astonishing part about the demo is listening to the audio using ordinary headphones. The processing and post-processing delivers a 7.1 home theater-quality surround sound experience. What’s more, HiFi’s low-energy benefits mean the technology can be designed into mobile applications, according to Liu. Here’s Liu discussing the technology: (Please visit the site to view this video) Brian Fuller Related stories : — Whiteboard Wednesdays: Implementing Always-On Audio — Cadence at CES 2015: How Electronic System Design Is Evolving — Cadence at CES 2015: The IP Story — Cadence at CES 2015: A Look at Face-Detection Technology![]()
