Role of Time-of-Flight Sensors in Automotive

The automotive sector is undergoing a profound transformation, moving beyond basic detection to a comprehensive, real-time 3D understanding of both the external environment and the vehicle's interior. ToF is emerging as a pivotal technology, offering precise 3D depth and distance information essential for navigating complex environments and understanding in-cabin dynamics.

Building a high-performance, low-power audio/voice subsystem

With the growing popularity of applications such as mobile gaming and voice triggering, the audio/voice subsystem is playing a prominent role in many mobile system-on-chip (SoC) designs. The subsystem must be designed to meet dual demands: high-performance, high-resolution audio stream processing as well as always-on, low-power voice trigger and recognition. Customizable digital signal processing (DSP) and audio/voice subsystem solution intellectual property (IP) blocks can provide a cost-effective and efficient way to develop and deliver high-performance audio/voice products.
