16-bit parallel descrambling data generation circuit with 16-bit parallel descrambler

摘要

The present invention relates to a 16-bit parallel descrambling data generation circuit of a 16-bit parallel descrambler in a CD-ROM decoder. In particular, the 16th descrambling data is obtained by using a current descrambling value. A 16-bit parallel descrambling data generation circuit of a 16-bit parallel descrambler that removes a register for storing a 16th descrambling value.;According to the present invention, in obtaining the 16th descrambling data, the register for storing the 16th descrambling data can be eliminated by using the current descrambling data without using the method of obtaining the previous value. It is easy to configure.
