TDAx ADAS SoCs – Mirror replacement/CMS

Mirror replacement systems replace the rear and side mirrors on vehicles with small cameras mounted on the outside and monitors on the inside of the vehicle. Mirror replacement systems offer multiple advantages over conventional mirrors such as reduced aerodynamic drag, improved fuel efficiency, better visibility under various conditions, better field of view with elimination of blind spots, and the ability to perform analytic functions like object detection.

Jacinto™ TDAx automotive processors are designed to address
the key needs of mirror replacement systems such as excellent image quality, low latency, safety, and high levels of integration. In addition, TI provides complete hardware and software scalability enabling easy development of optimized solutions and faster time to market.
