Provision of accurate and complete communication between different bus architectures.

The invention is connected with the CPU local bus and an external bus's main is connected with the logic, whether the hardware logic detecting is transmitted reverse driving the data and device on sides the CPU local bus, and replacing, the non-adjacency data with the data sides, and movable of for guaranteeing the CPU local bus without the fault. Hardware of the invention is for moving the data transmission and external bus and A local bus, an external bus limiting groove for structure is the measuring standard burst, the CPU local bus is permit the dynamic bus stage.
