Claim 0:
1. A metering device, comprising: a structure body of the metering device, a first metering chip and a metering master control chip, wherein:
the first metering chip is configured for performing fundamental wave and full wave processing on electric energy data;
the metering master control chip comprises a master control chip core, a coprocessor and a storage unit, wherein the master control chip core and the coprocessor share the storage unit; and
the coprocessor is configured for performing harmonic processing on the electric energy data based on the storage unit and based on a manner of instruction,
wherein the coprocessor is specifically configured for:
in a single-phase mode, based on the storage unit, performing N harmonic processing of single phase on the electric energy data by multiplexing a target instruction set for N times; and
in a three-phase mode, based on the storage unit, performing N harmonic processing of each phase on the electric energy data by multiplexing the target instruction set for 3N times; wherein, N is a positive integer.
