Algorithm implementation of high-precision large number division in C language (with practical cases)
1. Introduction In the process of solving problems in C language, we often encounter some problems that require large number processing. Large numbers defined here are integers with hundreds of digits. The usual approach is to convert large numbers into one-dimensional arrays and then perform four arithmetic operations. Among the four arithmetic operations, division is […]
Division and verification of virtual LAN (vlan) based on HCL environment
Experimental background: By dividing virtual broadcast domains into layer 2 switches, broadcast storms are logically isolated. First of all, it is clear that there are four methods for VLAN division, namely: 1. Port-based vlan; 2. valn based on MAC; 3. IP-based vlan; 4. Protocol-based vlan; This experiment is based on port vlan division. 1. Build […]
Switches and routers realize the division of different network segments, communication between different vlans, and specify combinations of vlans for network communication.
Switches and routers implement the division of different network segments, communication between different vlans, and designated combinations of vlans for network communication. I recommend a very easy-to-use free online tool for drawing: https://www.processon.com/i/5f58a647e658155997003a46 1. Examples of network requirements 1. Assume that there are three PCs A, B, and C, which need to be on different […]

Verilog implements decimal frequency division (taking 42.3, 1.5MHZ as an example) and key selection to adjust the frequency from 1 to 10HZ
1. Experiment purpose and requirements Use Verilog programming to implement decimal frequency division. The input clock signal frequency is 50MHz. First, the 42.3MHz clock signal is obtained by decimal frequency division from 50MHz, and then the 42.3MHz clock frequency is divided to obtain 1Hz, 2Hz, 3Hz, 4Hz, 5Hz, 6Hz, and 7Hz. , 8Hz, 9Hz, 10Hz […]
