Abstract
A bus controller (20) for a data processing system, in which data is transferred between a bus master (10) and a bus slave (30) of a plurality of different data port sizes, is able to obtain port size information from an address signal using an incorporated address area/port size correspondence table (211), whereby a port size signal as a response signal from the bus slave is made unnecessary, thus simplifying the data processing system.
