I recently got OpenCV up and running on my Zynq-7000 based Zedboard. The performance of the OpenCV samples I ran was very good even without using the FPGA fabric. I didn't get my OpenCv from Xilinx, but rather downloaded and built it from the generic ARM Linux source.
I really wanted to see how compatible the Zynq is to the rest of the ARM CPU/SOC world. The Linux distribution I'm using (Xillinux) is made for the Zynq, but pretty much everything else I used was generic. I built CMAKE, Mjpg-Streamer and OpenCV from non-targeted source files. The Mjpg-Streamer source I used was made for the Raspberry Pi. The others were generic ARM Ubuntu sources. I also downloaded and used a large number of generic source libraries - all of that without touching a single line of code.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
