crc 32 ieee

CRC16 Implementation CodeIdea: Take a character (8bit), check the character bit by digit, if it is 1,crc^crc_mul, and if the original CRC highest bit is 1, then crc^crc_mul the left 1 bits, otherwise it just moves left one bit. After calculating one

Absrtact: This paper first discusses the CRC's Algebra algorithm, then takes the common Crc-itu as an example, through the hardware circuit realization, has brought out the bit-type algorithm, finally emphatically introduced the byte type quick look-

The CRC is based on a checksum of modulo 2 operations.N=k+r.n is the length of the CRC code, K is the number of bits of the information code, and R is the number of bits of the checksum code.2 R-Square >=k+r+1 (correct).4 Useful information (1100)

IntroductionEthernet is the most successful LAN (local area Networking) technology in the last 30 years. 1. First widely used LAN technology (a widely used LAN technology) 2. Kept up and speed race:10 mbps–100 Gbps 3. connectionless: No handshaking

Serial communication refers to the serial port bitwise (BIT) Send and receive bytes. Although it is slower than parallel traffic by byte (byte), the serial port can receive data with another line while sending data using one line. Serial

Q: How do I implement a monolithic Ethernet microcontroller?A: The trick is to integrate microcontrollers, Ethernet media access controllers (Macs) and physical interface transceivers (PHY) into the same chip, which removes many external components.

Overview: Media independent interface (media-independent interface), or media-independent interface, is the Ethernet industry standard defined by the IEEE-802.3. It includes a data interface and a management interface between MAC and PHY. Data
