Abstract

A system for processing digital electrical power signals derived from at least one externally supplied, substantially continuous, substantially alternating, electrical signal having a primary or fundamental frequency, comprises: a multiply-accumulate arithmetic processor having three input ports with at least one input port for receiving the digital electrical power signals, an output port and a processor control port; a first memory unit for storing a plurality of processor control signals; a second and third memory unit each for storing a separate plurality of processor input signals; and a memory control unit having the capability to respectively couple the first memory unit to the processor control port, and the first processor input port to one of the second and third memory units for each cycle of the primary frequency so that newly received digital electrical power signals may be continually processed by the processor for a predetermined number of cycles.
