CENTRALIZED BUS COMMUNICATION EQUIPMENT AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a centralized bus communication equipment and a method capable of performing high speed communications by reducing the load capacity driven by each electronic part with a simple constitution. SOLUTION: A one-chip semiconductor integrated circuit is provided with an internal bus, and this semiconductor integrated circuit is provided with bus buffers 710-750 for realizing communications through the internal bus. Each electronic part is connected with the bus buffers 710-750 in a star form so that bus type communications are performed only inside the semiconductor integrated circuit. Therefore, it is possible to realize high speed communications by reducing the load capacity driven by each electronic part with a simple constitution.
