INTEGRATED CONTROL AND DECODING CIRCUITS FOR COMPACT DISK PLAYERS

摘要

An integrated control and decoding circuit for a CD player includes digital input means (14) for receiving input data read from the compact disk and control signals for controlling operation of the CD player. A RISC processor (12) serves both as a signal processor means for decoding and error correcting the input data and as a control means for controlling operation of the player. Digital output means (26) provide a plurality of digital output signals containing output data and control signals for controlling operation of the CD player. The digital input means (14), processor (12) and digital output means (26) are integrated onto a single semiconductor integrated circuit chip.
