Xilinx flexes its muscles in the ADAS arena

February 26, 2015 // By Christoph Hammerschmidt
With the latest generation of its Zync FPGA and microprocessor combination, Xilinx intends to address among other applications the automotive market. At Embedded World, the company demoed a number of applications highlighting the versatility of this concept.

For its newly introduced 16nm Ultrascale+ family of FPGAs and MPSoCs (multipcrocessor SoC) Xilinx claims significant performance benefits. Also the performance per watt, an important criterion in power-constrained environments such as ADAS and other automotive applications, has been increased considerably. The architecture combines an ARM Cortex R53 32-bit dual-core processor for real-time tasks with a Cortex A53 64-bit quad-core application processor and a high-end graphics-processing unit Mali-400MP, also from ARM. Also integrated are a power management unit that supports power gating and power islands, a broad selection of FPGA logic including RAM, interfaces and video codecs. For deployment in the connected car which involves high security and safety requirements, the device family also contains an integrated security unit with functions such as information assurance and key management. Lockstep options enable the deployment of the device in environments where functional safety as defined in ISO26262 is an issue.

In specific applications, Xilinx significant performance/power improvements - for example in an Automotive multi-camera driver assist system, the company claims the new Zync Ultrascale MPSoc quintuples the performance per watt, compared to an earlier configuration with double Zynq-7000 AP SoCs. Despite consuming 50% less power, the Ultrascale implementation has 2,5 times more application performance.
