<P>PROBLEM TO BE SOLVED: To maintain expansibility and flexibility in a bus system for performing communication between a plurality of devices. <P>SOLUTION: When a request of an audio processing device permitted to communicate from a bus controller 5 is a write request, data are sent from an FIFO (first in first out) of the audio processing device to a data bus 8. The data are written in a communication RAM 7 built in the bus controller 5. When a read request is outputted from an audio processing device which is a destination of the data, the bus controller 5 transmits the data read out from the RAM 7 to the audio processing device. <P>COPYRIGHT: (C)2003,JPO |
