“…An alternative to the CPLD is the use of a fieldprogrammable gate array (FPGA) for the node of sensors [15]. Other authors use a commercial board to build a standalone platform [16]. This commercial board combines a Spartan-3 (XC3S2000), a CPLD and a 128Mb flash memory.…”

In this work, a low power datalogger with a wireless connection is described. The datalogger can be used as a portable and stand-alone device, as well as a wireless sensor network node. A flexible architecture, which combines a microcontroller with external local buses (data and address) and a complex programmable logic device (CPLD), has been used. The system has two special characteristics: one of them is the high resolution of A/D converters; the second is based on the incorporation of a non-volatile random-access memory (NVRAM) that allows fast access to stored data and a low consumption. Storing data in an NVRAM implies an extra security level for the maintenance of data even when the batteries of the system have been exhausted. The complete glue logic has been integrated into a Zero-Power CPLD in order to reduce size. In addition, in each specific application, the CPLD allows the implementation through hardware of some interfaces to sensor module, saving computation time.

In this manuscript, we present a survey of designs and implementations of research sensor nodes that rely on FPGAs, either based upon standalone platforms or as a combination of microcontroller and FPGA. Several current challenges in sensor networks are distinguished and linked to the features of modern FPGAs. As it turns out, low-power optimized FPGAs are able to enhance the computation of several types of algorithms in terms of speed and power consumption in comparison to microcontrollers of commercial sensor nodes. We show that architectures based on the combination of microcontrollers and FPGA can play a key role in the future of sensor networks, in fields where processing capabilities such as strong cryptography, self-testing and data compression, among others, are paramount.

Specific features of Wireless Sensor Networks (WSNs) like the open accessibility to nodes, or the easy observability of radio communications, lead to severe security challenges. The application of traditional security schemes on sensor nodes is limited due to the restricted computation capability, low-power availability, and the inherent low data rate. In order to avoid dependencies on a compromised level of security, a WSN node with a microcontroller and a Field Programmable Gate Array (FPGA) is used along this work to implement a state-of-the art solution based on ECC (Elliptic Curve Cryptography). In this paper it is described how the reconfiguration possibilities of the system can be used to adapt ECC parameters in order to increase or reduce the security level depending on the application scenario or the energy budget. Two setups have been created to compare the softwareand hardware-supported approaches. According to the results, the FPGA-based ECC implementation requires three orders of magnitude less energy, compared with a low power microcontroller implementation, even considering the power consumption overhead introduced by the hardware reconfiguration.
