Ozray has implemented IP cores in its Pollux and Pamina area and line scan cameras and its Deneb thermal camera. In-house development of CXP and GigE transport layer interfaces would have been considerably more expensive than purchasing IP.
“By purchasing IP cores, we can focus internal engineering resources on image processing and controlling sensor functions to a degree that wasn’t possible in the past when so many resources were devoted to the camera-host interface,” Ahn said.
“We are also now able to address new markets by expanding our interface offerings from Camera Link alone in the past to now offering CXP and GigE as well. We are 100 per cent satisfied with the IP cores and services provided by S2I.”
Crevis’ Hwang said in the past it took a considerable amount of engineering manpower to develop the internal transmission logic, device drivers and Tx/Rx library for transport layer interfaces for its area scan cameras.
“Now we purchase IP cores for GigE, CXP and USB interfaces from S2I while our engineers focus on developing sensor interface and camera functionality,” Hwang said.
“S2I provides the reference design, training and technical support. This approach makes it possible to develop a reliable standard transmission interface in a fraction of the time required in the past. By incorporating IP cores into an FPGA that replaces many other parts, we have also reduced the size and manufacturing cost of our cameras.”
Sick’s Ranger 3 3D streaming camera offers a greater number of 3D profiles per second in combination with a large height range and high image quality. “Previous generations of the Ranger 3 used a proprietary Gigabit Ethernet interface in order to provide capabilities that could not be delivered by following the standard,” said Mattias Johannesson, senior expert, Software 3D Camera for SICK IVP AB.
“When the standard grew to include the features we needed, we wanted to adopt it but didn’t want to divert the engineering resources that would have been required to do the job internally. S2I offered a proven standard IP Core together with new custom modules to cover the extensions of the standard.
“We had very good communications with S2I throughout the implementation process including several face to face meetings. Our engineering team was able to focus on our imager and signal processor, making it possible to get the latest Ranger 3 version to market in considerably less time than would have been required if we had developed the interface in-house.”
“IP Cores enable machine vision companies to build FPGA-based products using the GigE Vision, USB3 Vision, and CoaXPress standards, delivering the highest possible performance in a small footprint while minimizing development time,” Schaffland concluded.
