reVISION stack boosts vision-guided machine learning

Article By : Xilinx

The stack offers up to 6x better images/second/watt in machine learning inference, according to Xilinx.

Targeting vision-guided machine learning applications, Xilinx's reVISION stack enables a much broader set of software and systems engineers, with little or no hardware design expertise to develop intelligent vision guided systems easier and faster by combining machine learning, computer vision, sensor fusion and connectivity, according to the company.

Xilinx said reVISION offers the fastest path to the most responsive vision systems, with up to 6x better images/second/watt in machine learning inference, 40x better frames/second/watt of computer vision processing and 1/5th the latency over competing embedded GPUs and typical SoCs. Developers with limited hardware expertise can use a C/C++/OpenCL development flow with industry-standard frameworks and libraries like Caffe and OpenCV to develop embedded vision applications on a single Zynq SoC or MPSoC.

Developers can use the stack to rapidly develop and deploy upgrades. Reconfigurability is critical to 'future proof' intelligent vision-based systems as neural networks, algorithms, sensor technologies and interface standards continue to evolve at an accelerated pace, according to the company.

The Xilinx reVISION stack includes development resources for platform, algorithm and application development. This includes support for the most popular neural networks including AlexNet, GoogLeNet, SqueezeNet, SSD and FCN. Additionally, the stack provides library elements including pre-defined and optimised implementations for CNN network layers, required to build custom neural networks (DNN/CNN). The machine learning elements are complemented by a broad set of acceleration-ready OpenCV functions for computer vision processing, according to Xilinx.

For application level development, Xilinx supports industry-standard frameworks including Caffe for machine learning and OpenVX for computer vision. The reVISION stack also includes development platforms from Xilinx and third parties, including various types of sensors.

The reVISION stack will be available in the second quarter of 2017.
