When users want to create embedded video or imaging applications, they find that PC/104 boards and systems are the right choice for their designs, and plenty of products are still being introduced that meet this venerable and proven specification. The reasons are well known. PC/104 provides a compact yet easily expandable architecture. It is suitable for harsh environments where imaging applications may be needed, thanks to its rugged and reliable connectors. It is resistant to shock and vibration, which can be important for imaging. And of course, it’s compatible with PCs, keeping the cost and time involved in development down.
In particular, PCIe/104 offers flexibility for functions an imaging application may need, such as four-port Gigabit Ethernet and USB 3.0 connections. And it maintains flexibility for future expansion. One recent example of a vision system that took advantage of PCIe/104 was a fish-counting system developed for the National Marine Fisheries service by PC/104 Consortium members ADL Embedded Solutions Inc. and RTD Inc. The service needed a camera system that could withstand the vibrations of a trawler in the water while providing real-time image processing.
Several companies have products that are compatible with the PCIe/104 standard. For example, if you’re needs include ultra-low latency, you might want to check out the H264-HD-2SDI from Advanced Micro Peripherals (Ely, UK), a dual-channel H.264 encoder for PC104 OneBank. It features ultra-low latency of 40 ms and provides Key-Length-Value metadata. It offers high definition, allowing dual-channel encode up to 1080p30 and single-channel encode up to 1080p60. The board is designed for high-resolution surveillance and traffic monitoring, and can be used in unmanned aerial vehicles and remotely guided vehicles.
