Digital signal process device and method for electric energy metering chip

A digital signal process device for an electric energy metering chip, comprising:

• a first kernel module, configured for generating a corresponding control signal according to a DSP instruction code in a first read-only memory;
• a second kernel module, configured for generating a corresponding control signal according to a DSP instruction code in a second read-only memory;
• wherein a DSP instruction comprises an arithmetic instruction, a memory access instruction, a jump instruction and a no-operation instruction;
• an arbitration module, respectively connected with the first kernel module and the second kernel module, configured for receiving the control signal corresponding to the memory access instruction and/or the arithmetic instruction sent by the first kernel module and the second kernel module, and screening out the control signal corresponding to a target memory access instruction and/or a target arithmetic instruction according to a preset priority;
• a data storage module, connected with the arbitration module, configured for receiving and executing the control signal corresponding to the target memory access instruction sent by the arbitration module;
• and
• an arithmetic logic unit, connected with the arbitration module, configured for receiving and executing the control signal corresponding to the target arithmetic instruction sent by the arbitration module.
