Theory: 4-byte error code EDC: In the CD-ROM sector, there is a 4-byte 32-bit EDC domain, which is used to store the CRC code. The CRC verification code of the CD-ROM generates a polynomial of 32th order, p (x) = (x16 + x15 + X2 + 1) (x16 + X2 + x + 1 ). The data block used to calculate the CRC code is the Data byte from the beginning of the slice to the end of the user data zone. Take mode1 as an example, That is, a total of 2064 bytes are between 0 and. Add 4 bytes of data to 0, and then divid

early computer bus shared parallel architecture, each device has its own dedicated connection, you do not need to request bandwidth from the entire bus, and you can increase the data transmission rate to a high frequency to achieve the high bandwidth that PCI cannot provide. Compared with the traditional PCI bus, only one-way transmission can be implemented in a single time period, the dual-ticket connection of PCI-E can provide higher transmission rate and quality, and the difference between t

PCI-E 30,000 Gigabit Ethernet product IP DevelopmentThis board card is based on the Virtex7 xc7v690t-1ffg1761i, the design of the PCIe Backplane, the board features are as follows:1, Standard PCI-E interface, support PCI-E 8x, support PCI-E 3.0.2, the standard FMC-HPC interface, the Vadj level is 1.8V.3, the front panel out of the 1-way SFP + optical module, the highest design speed of 10Gbps.4, the board behind the 2-way SFP + optical module, the highest design speed of 10Gbps.5, support two g

points. Since each line in the TV signal includes a certain synchronous signal and a back sweep signal, the effective sample point of the image signal is not so much, CCIR 601 provides for all the standard, the effective sample point of each line is 720 points. Because different formats have different valid rows per frame (PAL and SECAM are 576 lines, NTSC is 484 rows), CCIR defines 720x484 as the basic standard for HDTV HDTV (High Definition TV). When the actual computer displays digital video

(generator polynomial): When the CRC test, the sender and receiver need to agree with a divisor, that is, to generate a polynomial, generally written as g (x). The highest and lowest bits of the generated polynomial must be 1. The common CRC code generation polynomial is:Crc8=x8+x5+x4+1Crc-ccitt=x16+x12+x5+1Crc16=x16+x15+x5+1Crc12=x12+x11+x3+x2+1Crc32=x32+x26+x23+x22+x16+x12+x11+x10+x8+x7+x5+x4+x2+x1+1Each

4:2:2 format, the amount of data for the digital video is:13.5 (MHz) x8 (bit) +2x6.75 (MHz) x8 (bit) = 27mbyte/s can also be calculated, if sampled by 4:4:4, the amount of digital video data is 40 megabytes per second! A 10-second digital video consumes 270 gigabytes of storage space at a data rate of 27 megabytes per second. According to this data rate, a 680 megabyte CD-ROM can only record about 25 secon

bits after multiplication 2 will overflow, the result is subtracted from an irrevocable polynomial (X8 + X4 + X2 + x + 1). Note that the subtraction in GF (2 ^ 8) is addition, then, the result is that the original value is shifted to the first digit (multiplied by 2) and then (0001 1011) 2, that is, 0x1b, or (X8 has been reduced here, you only need to subtract X4 + X2 + x + 1 ).3.

5.3 Bitwise Operators The difference between Turbo C and other advanced languages is that it fully supports bitwise operators. This is somewhat similar to the bit operation of assembly language. The bitwise operators in Turbo C are: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ operator function ──────────────────────────── Bit Logic and | Bit logic or ^ Bit logical xor or -bit logic counter >> Move Right ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Bitwise operations are the detection, setting, or shift of the actual bits in
