C-SKY Microsystems selects Dolphin Integration’s energy management offering for smart voice-interacted devices

Dolphin Integration, the leading provider of solutions for Energy Management, and Hangzhou C-Sky Microsystems, a China-based embedded microprocessor core IP provider, announced today their collaboration on an ultra-low power human-machine interface SoC platform. In this collaboration, C-Sky has licensed from Dolphin Integration a complete and consistent offering of silicon IPs, together with the PowerVision™ simulation platform, to design a new generation of SoC platform capable of demonstrating human-machine voice recognition interactions.

"The emergence of powerful voice recognition algorithms drives the growth of connected devices controlled by voice, where voice recognition and ultra-low power technologies are key to delivering the optimal user experience," said Thomas Xu, VP of Marketing at C-Sky. "The complete set of Foundation, Feature and Fabric IPs of Dolphin Integration will allow us to demonstrate fast and safely a human-machine interaction system relying on a C-Sky microcontroller-based SoC platform".


Based on C-Sky’s energy efficient embedded processor core, human-machine interaction platforms will adopt advanced voice processing alogirthms so as to ensure maximum voice clarity and intelligibility in any environment and from any direction. To combine at once the longest operation on battery without recharge with always-on and high performance voice recording, C-Sky microcontroller-based SoC platform will embed the Dolphin Integration breakthrough WhisperTrigger™, an ultra low power voice activity detection IP, together with their high dynamic range and low noise floor audio CODEC.

"By leveraging our "Trio" offering, combining state-of-the-art Silicon IPs with a unique simulation platform, for power noise integrity driven design, and advanced design methodologies, all proven in the Taishan Demochip at 55 nm, C-Sky can exploit the capabilities of its CPU to deliver compelling demo systems." said Frederic Renoux, director of sales at Dolphin Integration. "We are pleased to support C-Sky to meet the demands of an increasingly voice-interacted world."
