PROBLEM TO BE SOLVED: To provide a data bus communication system and a data bus communication control method which can perform necessary and sufficient data transfer with high degree of flexibility of timing and amount of data with extremely small number of wiring and very simple organization. SOLUTION: This data bus communication system is set up so that transmission and reception of an information signal from an information processor 1 of a host side to a desired information processor 2 of a client side can be performed at desired transfer timing only by connecting at least one read/write selection signal line 3, one data strobe signal line 4, and one acknowledge signal line 5 for one information processor 2 at the client side. The number of wiring for controlling transmission of information signal by a data bus 8 is remarkably reduced. COPYRIGHT: (C)2005,JPO&NCIPI
