The invention discloses a characteristic parameter absolute increment method for asymmetric power distribution network ground fault processing, and the method comprises the steps: detecting the capacitive current, neutral point displacement voltage UN and zero-sequence current of each feeder line of a power distribution network through a ground fault processing device; and storing the lead load current corresponding to the asymmetric abnormal feeder line in a storage of the grounding fault processing device as a reference value. And after the influence of dynamic asymmetry of the power distribution network is eliminated when the neutral point displacement voltage stably changes, the absolute increment of the fault characteristic parameter is calculated by comparing the fault characteristic parameter with the absolute increment of the fault characteristic parameter when the power distribution network normally operates, so that the high-resistance grounding fault is identified and processed.

This invention provides an instruction issuing method and apparatus based on asymmetric functional units and dynamic detection, relating to the field of processor technology. Specifically, the issuing unit obtains information such as the instruction type and source register number from the decoding unit, detects the data dependency between the issuing unit's instruction and all instructions in the pipeline, and generates a control signal to fetch source operands from a bypass based on the above information. Regardless of whether the source operands are ready, the issuing unit issues the instruction. If the source operands are not ready at the time of issuance, the dependency is dynamically detected at each stage of the subsequent pipeline based on the current instruction state, and the bypass control signal is updated in real time to ensure the correctness of the operands during instruction execution. Based on the asymmetric distribution of functional units in the pipeline, the issuing unit can schedule dependent instructions of the same type to be executed in different functional units within the same issuance cycle without causing pipeline stalls. The issuing method of this application decouples data dependency and instruction issuance to the greatest extent possible, allowing instructions to be issued in advance even if the dependency is not resolved, and decoupling the dependency in the pipeline, significantly improving instruction issuance efficiency and facilitating the optimization of the issuing unit's timing.
