ABSTRACT:
A microprocessor with a bus sizing function has internal data bus and external data bus having 2.sup.n bit width, in which n is a natural number, for inputting and outputting data to and from said data path, 2.sup.n interface circuits having a bus sizing function for using as a bus of 2.sup.m bits, in which m is a natural number smaller than n, said interface circuit being connected to 2.sup.n-m of internal data buses and 2.sup.n pads for connecting said internal data bus to the external data bus via said interface circuit. Among said interface circuit and said pads, 2.sup.n-m of said interface circuits and said pads associated with common internal data bus are aggregated as a block and arranged at close proximity to each other.
