Embedded Systems
Virtually any electronic product today contains embedded microprocessor systems for different purposes. It could be for controlling a user interface, to enable remote communication or for monitoring and controlling the product functionality. Embedded systems span a vast field of varying functionality and complexity.
We do develop embedded microprocessor systems and have experience with everything from small, low-energy 8 or 16 bit controllers up to powerful 32-bit processors running Linux. Applications of particular experience are control of analog and microwave systems, short range radio systems and systems with graphical user interface.
RF and microwave systems intended for operation over a wide temperature range often show large variation of parameters like gain and linearity. To enable constant performance over temperature, processor control and compensation is used.
Short range unlicensed radio can be built around well-known protocols like Zigbee, Bluetooth, ANT et cetera. Sometimes standardized protocols contain unnecessary functionality for a certain application and leads to high power consumption. A proprietary protocol, containing only a minimum of functions, can be an attractive energy saving alternative.
Systems with display windows can be an EMC challenge. Exact control over data and address buses, display drivers and power supply lines is a must. Our RF knowledge is a useful tool in mastering this type of designs.
