Abstract
A DSP-based electrical energy metering device is provided. After determining a current application mode, a DSP controller compares an execution rate of each computing task with a corresponding preset comparison value, and outputs a first condition value to a condition general register based on a comparison result, so as to control an execution rate of each computing task in the DSP controller. A jump condition controller outputs a second condition value corresponding to the current application mode to the condition general register based on a change in the execution rate of each computing task compared with an execution rate of the computing task in a previous application mode, so that all computing tasks are executed. An adaptive word length controller adjusts an effective bit width of the electrical signal read by a data general register from a data memory at execution rates of different computing tasks.
