Driver Assistance and ADAS

Reliable, Secure, Low Power ADAS Applications

A higher level of functionalities expected in next-generation cars like driver assistance requires a higher level of performance and multi-sensor fusion systems. Lattice FPGAs address these evolving needs for a flexible and scalable domain controllers design to meet cost and power needs.

  • Enabling parallel sensor data processing with customized low latency networking solution for real time decision making at domain controllers or redundant decision processor systems
  • Enabling low-power multi-sensor interfaces for sensor fusion applications and display interfaces
  • Enabling protection against cyber-attacks while ensuring safety using Lattice FPGA’s hardware-based security, low Soft Error Rates (SER), and Functional Safety (FuSa)
