Energy Consumption and Energy Density in Optical and Electronic Signal Processing

IEEE Photonics Journal, 2011
We compare the energy consumption of digital optical and digital electronic signal processing circuits, including the contributions to energy consumption of the optical to electrical (O/E) converters and electrical to optical (E/O) converters, and the ...

On the energy landscape of symmetric quantum signal processing [PDF]

Quantum, 2022
Symmetric quantum signal processing provides a parameterized representation of a real polynomial, which can be translated into an efficient quantum circuit for performing a wide range of computational tasks on quantum computers. For a given polynomial $f$

EC-CENTRIC: An Energy- and Context-Centric Perspective on IoT Systems and Protocol Design [PDF]

IEEE Access, 2017
The radio transceiver of an Internet of Things (IoT) device is often where most of the energy is consumed. For this reason, most research so far has focused on low-power circuit and energy-efficient physical layer designs, with the goal of reducing the ...

Linear optical wave energy redistribution methods for photonic signal processing

npj Nanophotonics
Manipulating the phase of an optical wave over time and frequency gives full control to the user to implement a wide variety of energy preserving transformations directly in the analogue optical domain. These can be achieved using widely available linear

Optimizing Solar Power Using Array Topology Reconfiguration With Regularized Deep Neural Networks

IEEE Access, 2023
Reconfiguring photovoltaic (PV) array connections among different topologies such as series-parallel, bridge-link, honeycomb, or total-cross-tied is a popular strategy to mitigate impediments in power production caused by partial shading.

System for powering autonomous solar cookers by batteries

Scientific African, 2022
In this paper, we propose innovative autonomous solar cookers (hot plates and box ovens) supplied by batteries. The electrical energy is produced by photovoltaic panels (PV) and stored in a battery (24 V, 520 Ah). Hence, the cookers are powered through a

Energy-efficient signal processing using FPGAs [PDF]

Proceedings of the 2003 ACM/SIGDA eleventh international symposium on Field programmable gate arrays - FPGA '03, 2003
In this paper, we present techniques for energy-efficient design at the algorithm level using FPGAs. We then use these techniques to create energy-efficient designs for two signal processing kernel applications: fast Fourier transform (FFT) and matrix multiplication.
