Abstract
A bit-serial processor for selectively carrying out the sequential steps of performing by successive approximations Coordinate Rotation Digital Computation (CORDIC), non-restoring division or non-restoring square rooting calculations is suitable for inclusion in a monolithic integrated circuit with a plurality of sensors for generating respective sensor output signals, circuitry for converting each sensor output signal to bit-serial digital format, and a bit-serial muliptly-add processor. Together with an electrically-erasable programmable read-only memory and a plurality of current transformers, the monolithic integrated circuit implements a system for metering a-c power main conductors.
