The ABB AI620 processor module is a core component in computer systems, responsible for performing arithmetic, logic, branching, and jumping operations. It includes the following key components: execution unit: responsible for performing arithmetic and logical operations, storing data in registers, and handling branch and jump operations. Register heap: stores data and states that need to be processed internally by the CPU, such as instruction counters, accumulators, etc. Cache: stores data that needs to be accessed frequently within the CPU to improve access speed and efficiency. Bus: responsible for transmitting data and instructions, transferring data between various components within the CPU. Floating point unit: responsible for handling floating-point operations. Control unit: The command and control center of the entire CPU, based on the user’s pre programmed program, sequentially extracts each instruction from the memory, places it in the instruction register IR, decodes (analyzes) the instruction to determine the operation to be performed, and then the operation controller OC sends micro operation control signals to the corresponding components according to the determined timing. Operation unit: The core of an algorithm, which can perform basic operations such as arithmetic and logical operations. Storage Unit: The storage unit of the CPU module includes CPU on-chip cache and register groups, which are temporary storage locations for data in the CPU.

In addition, companies such as Siemens also provide central processing unit modules, such as the Siemens S7-1500CPU module and the Siemens CPU1211C central processing unit module. These modules can be used for different automation and control systems. The ABB AI620 processor module is a core component in computer systems. Its function is to receive and store user programs and data, collect status or data sent by on-site input devices through scanning, and store them in designated registers. Diagnose the working status of the power supply and PLC internal circuits, as well as syntax errors during the programming process. After entering operation, read instructions one by one from the user program memory, analyze them, and then generate corresponding control signals according to the tasks specified in the instructions to command the control circuit.
