Probabilistic arithmetic and energy efficient embedded signal processing [PDF]
Proceedings of the 2006 international conference on Compilers, architecture and synthesis for embedded systems, 2006 Probabilistic arithmetic, where the ith output bit of addition and multiplication is correct with a probability pi , is shown to be a vehicle for realizing extremely energy-efficient, embedded computing. Specifically, probabilistic adders and multipliers, realized using elements such as gates that are in turn probabilistic, are shown to form a natural ...

Energy processing techniques for stress wave emission signals [PDF]
The Journal of the Acoustical Society of America, 1979 This paper describes the construction of two circuits capable of measuring the energy of transient signals, in particular, stress wave emission (SWE) signals. Energy of SWE signals cannot be measured by conventional energy meters since these meters require a repetitive signal, and by nature SWE signals are nonrepetitive.

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.
