Embedded In The Cd-rom Interface Design

This paper discribes the design of CD-ROM interface in embedded systems,which eliminates the IDE interface and enhances the antivibration. This technique is very suitable for vehicle navigation system. The work principle of the CD-ROM system and the algorithm of data encoding decoding are introduced. The circuit of the interface based on FPGA is proposed. The principle of the system and the implementation of software and hardware is given. The result of the test is analyzed.
