Other AbstractThe invention relates to a specific processor system structure for a high-performance programmable controller and an implementation method of the dedicated processor system structure. The specific processor system structure comprises a PLC (Programmable Logic Controller) specific instrument set processor and a general processor, wherein the PLC specific instrument set processor is connected with a general processor through the PLC specific instrument set processor and an interface of the general processor. The implementation method comprises a four-level flow line consisting of a fetch stage,a decoding stage, an executing stage and a writing-back stage, according to the PLC specific instrument set processor. By designing the PLC specific instrument set which accords with the PLC instrument characteristics, the number of instruments for executing a PLC processor is reduced, the execution speed of a PLC program is accelerated, and the processing performance of the PLC processor to a functional block is improved.
