Description: ECC/EDC algorithm theory: 4-byte error detection code EDC: CD-ROM sector, there is a 4-byte word of 32-bit EDC domain, it is used to store CRC code. CD-ROM of the CRC checksum generation is 32-order polynomial, P (x) = (x16+ x15+ x2+1) (x16+ x2+ x+1). CRC codes used in the calculation when the data block from the sector at the beginning of the end of the user data area of data bytes to Mode1, for example, that a total of 2064 bytes 0-2063 bytes. Data plus 4 bytes of 0, and then addition to polynomials, I get the number of checksum.
