Nelder-Mead algorithm (NMA) is the best-known algorithm for multidimensional optimization without involving derivative computations. Due to the simplicity in implementation and the fast convergent property of NMA, it is widely used in the fields of statistics, engineering, physics and medical sciences. In practice, when objective function is complicated, the optimization procedure requires a lot of...
Nowadays, System-on-Chip architectures are composed of several execution resources which support complex applications. These applications increasingly need flexibility to adapt to their environment. Embed a reconfigurable resource in these SoC enables to flexibilize the hardware by sharing silicon area and limiting the cost of the global circuit. Partial reconfiguration is more and more used since...
Security is a key consideration when deploying wireless sensor networks (WSNs). Since the battery life confines the lifetime of a sensor node, power consumption is normally set as the first priority in developing security solutions. Due to the hardware resources constraint, lightweight cryptographic primitives are often implemented on sensor networks for ultra low power consumption. Apart from the...
We consider circuit techniques for reducing field-programmable gate-array (FPGA) power consumption and propose a family of new FPGA routing switch designs that are programmable to operate in three different modes: high-speed, low-power, or sleep. High-speed mode provides similar power and performance to traditional FPGA routing switches. In low-power mode, speed is curtailed in order to reduce power...
