Predicate logic gates, components and a processor are proposed for space–time signals and computing. Voltage impulses are transmitted along two wires and the signals are considered as predicate expressions. The developed simple gates and components perform the predicate logical operations AND, NOT, and OR with these expressions. For design and verification of all components and the processor, the CPLD and FPGA boards and corresponding software are used. The designed processor is compatible with classical computers and applicable in the area of artificial intelligence as well as linguistic calculations, database machines, SQL servers, etc.
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.
