SPONSORED: INDUSTRIAL EMBEDDED VISION


Teissié continued: ‘It’s very easy to get an off-the-shelf embedded development kit and use it to get something working. Te question is around reliability. Can it be produced for many years? How sustainable is the lifecycle? Some of the chips have a long lifecycle, whereas the boards and the development kits are refreshed every year- and-a-half to two years. In the industrial space, long-term availability is key. So the designers have to do it themselves, managing obsolescence and updating their systems. Tey have to make sure that these pass all testing and certification, are reliable and can withstand harsh environments. Tey have to maintain all of this over the lifetime of the product and ultimately, that is a big investment. Te alternative is that they select a platform from a manufacturer that can commit to supporting their business for the long-term.’


Simplification solutions In the latter case, vision application designers are looking to manufacturers for solutions that simplify these stages. For Lucid, this has involved a collaboration with AMD Xilinx, leveraging the Zynq UltraScale+ multiprocessor system-on-a-chip (MPSoC) to provide a solution for customers facing these challenges. Zynq devices are designed to provide 64-bit Arm processor scalability, combining


real-time control with soft and hard engines. Tey are built on a common real- time processor and programmable logic equipped platform. Lucid has integrated the Zynq chipset into its latest development, the Triton Edge camera. Teissié revealed: ‘We have a strong partnership with AMD Xilinx and are leveraging the development framework, as it can adapt to various customers – from the application specialist to the embedded software engineer, all the way to the hardware developer dealing with the field-programmable gate array (FPGA). Te Triton Edge is an expandable platform that designers can get running very quickly using the off-the-shelf tool we have built in with the Zynq interface.’ Te camera is designed to help vision


application designers, avoiding hardware validation required to qualify a product for challenging environments – with IP67 protection, it is certified against physical shocks and vibration, offers EMC industrial immunity and operates at temperatures between -20°C to +55°C ambient. Lucid and AMD Xilinx also manage the miniaturisation process before the camera reaches the designer – the Triton Edge features a compact size at 29 x 44 x 45mm. High-speed video direct memory access (AXI VDMA) is allowed for between the on-camera image signal processor, user-programmable FPGA and on-board RAM, while the Arm cores

use their own direct memory access (DMA) engine, freeing up the processors from managing data transfers. Te video direct memory access (VDMA) and DMA also help reduce system bottlenecks, frame buffer overhead and memory access latency, so that designers can focus on the efficient running of the vision processing. ‘Te embedded FPGA is really the uniqueness of this camera, that part of the FPGA is open for the customer,’ said Teissié. ‘Te FPGA is optimised for low- level or parallel processing tasks. It could be accelerating an AI engine, or a more standard computer vision type of processing running on the FPGA of the camera.’ In the future, Teissié predicts that major


advancements and new use cases will come from designers customising this tech for their own requirements. ‘You really can customise these systems,’ he said ‘It’s at a low level as well, so we have no intention of becoming a solution provider ourselves – however, we are working with a variety of partners that can offer this type of solution and we are eager to see how people use it. We are already seeing many communities and open-source resources with lots of information sharing – but these advancements are not really the hardware side – more analytics, AI or deep learning processing. We are looking forward to seeing what comes next.’ O
