Claim 1:
2. The metering device according to claim 1, wherein the coprocessor comprises:
an instruction controller configured for acquiring an instruction from the target instruction set of the storage unit through an instruction bus according to a preset instruction jump rule;
an instruction decoding executor configured for parsing the instruction sent by the instruction controller and executing the instruction, and when executing data acquisition, based on a current mode and a current value of a counter register, acquiring data information of a currently needed harmonic of a target order from the storage unit through a data bus and based on a virtual remapping manner and storing the data information in a general purpose register;
the general-purpose register configured for performing data interaction with the storage unit and with a basic arithmetic logic unit; and
the basic arithmetic logic unit configured for performing a logical operation on the data stored in the general-purpose register according to an arithmetic command sent by the instruction decoding executor, so that the coprocessor realizes the harmonic processing on the electric energy data.
