ADAS domain controller

Block diagram

Overview

Our highly integrated reference designs use scalable processing, power and communication interfaces to achieve different levels of performance in advanced driver-assistance systems (ADAS) domain controller applications. Scalable power solutions and interface protocols allow for highly-optimized solutions with our suite of Jacinto processors.

Design requirements

Modern ADAS domain controller designs require:

  • High power, efficient solutions for video and object data processing.
  • Safety diagnostics included or added to the system to ensure operation in all conditions.
  • High- and low-speed communication interfaces to be used with sensor modules with or without processing.
