Advanced Driver Assist Systems (ADAS)
Improving Driver Awareness & SafetyAdvanced Driver Assistance Systems (ADAS) continue evolving to deliver not only improved passenger experience and comfort, but provide optimum and safety to the driver. Enabling better situational awareness and control to make driving easier and safer, ADAS technology using FPGA/SoCs and automotive sensors can be based upon systems local to the car, i.e. “vehicle resident systems” like vision/camera systems, sensor technology, or on smart, interconnected networks as in the case of vehicle-to-vehicle (V2V), or vehicle-to-infrastructure (V2I) systems, jointly known as V2X systems. V2X communications use on-board dedicated short-range radio communication devices to transmit safety related messages about a vehicle's speed, heading, brake status, vehicle size, etc. to other vehicles and receive the same information about other vehicles from these messages. Using multi-hops to transmit messages through other nodes, the V2X network can communicate over long distances. This longer detection distance and ability to “see” around corners or through other vehicles helps V2X-equipped vehicles perceive some threats sooner than sensors, cameras, or radar can, and warn their drivers accordingly. In conjunction with V2I, the potential safety advantages of a wide-scale implementation are enormous. Potential V2I safety applications include:

Microsemi SoC FPGAs and FPGAs provide core data acquisition, processing and display functions while providing industry’s best reliability and security in small footprint packages crucial for building differentiated, secure and reliable advanced driver assist systems.
Microsemi offers best-in-class security for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. Among the available security services, Microsemi offers the most effective authentication feature when an SRAM based physically unclonable function (PUF) is used to compute the private key for identifying a device. Also critical is the use of a public key infrastructure (PKI) for distributing and ensuring associated public keys are authentic.
