The powerful data processing power of the central processor effectively improves the working efficiency of the computer. In the data processing operation, it is not only a simple operation. The operation of the central processor is built on the basis of the instruction task issued by the computer user. With the rapid development of information technology, computer is widely used in people’s life, work and enterprise office automation, as a kind of main control equipment, plays a role in promoting the development of electronic commerce network, making the upgrading process of CPU control performance greatly improved. Instruction control, actual control, operation control and so on are the performance of computer CPU technology application.
(1) Selection control. The operation of centralized processing mode is implemented on the basis of specific program instructions to meet the needs of computer users. The CPU can be selected according to the actual situation in the operation process to meet the data flow needs of users. Command control technology plays an important role. According to the user needs to formulate the operation mode, so that the orderly development of data command action is well maintained. In the execution of CPU, the implementation of each program instruction is completed in accordance with the smooth, only make it follow a certain sequence, to ensure the effect of computer use. CPU is mainly used to automate data set processing, which is the key to realize centralized control. Its core is instruction control operation.
(2) Insert control. The generation of operation control signals by CPU is mainly realized through the function of instructions. By sending instructions to corresponding components, the purpose of controlling these components is achieved. To achieve an instruction function, mainly through the computer components to perform a sequence of operations to complete. More small control elements are the key to build a centralized processing mode, in order to better complete the CPU data processing operations.
(3) Time control. The application of time timing to various operations is called time control. When executing an instruction, it should be completed within the specified time. The CPU instruction is taken out from the cache or memory, and then the instruction decoding operation is carried out, mainly in the instruction register. In this process, attention should be paid to strictly control the program time.
