Overview

WhisperTrigger allows your system to detect voice activity and increase its battery life. Our robust and silicon-proven, Voice Activity Detection solution, provides ultra-low-power Always-On Voice listening IP for a fast time to market. The WT-d.03 is a pure logic Virtual Component (ViC) containing a Voice Activity Detection (VAD) engine for ultra-low power applications. The WT-d detects the presence of a voice at the output of a DMIC or at the output of a voice ADC embedded on SoC to switch on the system to perform Keyword Spotting.

Key features

  • Voice activity detector enables drastic reduction in power consumption
  • Self-adjustment to background noise
  • Ambient Noise sensing

Audio Validation in Multimedia Systems and its Parameters

In the massive world of multimedia, sound stands as a vital component that adds depth to the overall encounter. Whether it's streaming services, video games, or virtual reality, sound holds a crucial role in crafting immersive and captivating content.

Using audio codecs IP as the digital audio hub in mobile multimedia systems

By integrating an audio analog codec that implements the 'audio hub' functionality and is able to process and mix audio signals from asynchronous sources, system designers can free the scarce main processor resources for more relevant tasks and simplify the system design, thus achieving a more effective solution.

Application Hardware Modeling: Selective modeling for early prediction of subsystem performances through simulation

The virtual validation of subsystem performances (Pop-up Noise, Signal-to-Noise Ratio, Power supply Noise, Power consumption...) requires the modeling and simulation of complete subsystems. Application Hardware Modeling (AHM) consists in addressing the risks of performance degradation while integrating a Silicon IP in its Integrated Circuit (IC) and this IC on its Printed Circuit Board (PCB). The selection of relevant models for a subsystem performance, along with the creation and validation of models through equivalence checking, are the basics of Application Hardware Modeling for right-on-first-pass subsystems!
