Information processor using optical storage medium.

摘要

The present invention provides an information processing apparatus using an optical storage medium, wherein the data in an optical storage medium such as a CD-ROM are processed with a plurality of processors of CPUs effectively and at a fast processing time to reduce the wait time of a user. Picture data, program data and audio data stored in an optical storage medium such as CD-ROM are transferred to a main ROM which can write and read data. Buses are changed so that the first and second CPUs can share a main ROM in time so that the two CPUs different as to the processing rate and the bit number to be processed can be used effectively.
