Switches work on the second layer of the OSI reference model, the data link layer. The CPU inside the switch will form a MAC table by matching the MAC address with the port when each port is successfully connected. In the future communication, the data packet sent to this MAC address will only be sent
The main reason for the emergence of motion control cards is: (1) In order to meet the standardization, flexibility, openness and other requirements of the new CNC system; (2) In the development and transformation of automatic control system of various industrial equipment (such as packaging machinery, printing machinery, etc.), national defense equipment (such as tracking
Motion control card is an upper control unit based on PC and industrial PC, used for various motion control occasions (including displacement, speed, acceleration, etc.). Motion control card is based on PC bus, using high performance microprocessor (such as DSP) and large-scale programmable devices to achieve multiple servo motor multi-axis coordinated control of A high

Central processing unit (CPU), is one of the main electronic computer equipment, computer in the core accessories. Its main function is to interpret computer instructions and process data in computer software. CPU is the core component of the computer which is responsible for reading, decoding and executing the instructions. The central processing unit mainly includes
How the dongle works: We take an example to illustrate the use of single chip algorithm. For example, A program might say: A=Fx(3). The program uses the constant 3 to get the value of the variable A. Thus, we can rewrite the original program as follows: A=Fx(DogConvert(1)-12342). The constant 3 does not appear in the
The latest hardware encryption principles At present, the world's most advanced Sungogo has introduced the double algorithm secure channel technology, which simultaneously adopts 128-bit AES algorithm and 160-bit ECC algorithm as communication encryption means. Each data transmission is encrypted with 128-bit random key AES algorithm, and the random key is encrypted with 160-bit ECC algorithm,
CPU structure Generally speaking, the structure of CPU can be roughly divided into operation logic components, register components and control components. The so-called operation logic unit, mainly able to carry out related logic operations, such as: can perform shift operation and logic operation, in addition to can also perform fixed point or floating-point arithmetic operation
