The use of SoCs allow a compact and low cost postprocessing system for monitoring electrical magnitudes. The main idea of this work is to have a small hardware which is deterministic enough to execute acquisition and sufficiently power to process data at a low cost.In this paper, it is presented two problem domains of electrical systems measurement, one with acquisition of 1 kHz and the other with 5 kHz. It was built an acquisition test bed with a SoC with standard and real-time Linux to compare and evaluate its timing constraints.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
