In the last years power dissipation has assumed a more and more relevant role in the design of complex integrated circuits, within the which embedded systems represent an important category. Among the currently available design languages, SystemC represents a suitable choice for the modelling of embedded architectures, due to the to its capability to model both software and hardware components properly...
This article reports the first results on fast and accurate power evaluation in arithmetic operators. The proposed method uses two steps: 1) accurate useful activity evaluation, 2) fast glitching activity estimation. The first step is based on circuit emulation using FPGA. Activity counters are inserted into the low-level description of the evaluated operator. The modified description is synthesized...
The underwater target localization problem is one important application for underwater acoustic sensor networks. This paper, based on "underwater acoustic transmission theory", solves the target localization problem. The proposed algorithm firstly studies the principle of underwater acoustics and applies it to set up the model of underwater signal energy transmission. According to the model,...
