Other AbstractThe utility model relates to a processor architecture special for a high-performance programmable logic controller (PLC). The processor architecture includes a PLC application specific instruction processor (ASIP), and a general processor, wherein, the PLC ASIP is connected to the general processor via the interface of the PLC ASIP and the general processor the PLC ASIP includes an instruction memory, an instruction counter, an instruction register, an instruction decoder, a control unit, a functional block unit, a functional block register group, a data memory, a register group, a bits processor, a jump & call instruction and access instruction processing unit, I/O data memory and a state register, The processor architecture reduces the instruction number executed by the PLC processor and accelerates the execution speed of the PLC program by designing the PLC specific instruction-set which is accord with the PLC instruction characteristics, thereby improving the processing performance of the PLC processor on functional block instructions.
