<p>PROBLEM TO BE SOLVED: To prevent increase of an area of a wiring region on a substrate, which is caused by the requirement to cross a wiring on a substrate if any of an arrangement order of a port and an arrangement order of a bit of data is uneven between both ICs during connection of a plurality of ICs on the same substrate. SOLUTION: In a digital signal processing block 21, data path switches (1) 32-1, 32-2 are disposed in a preceding stage (input side) of signal processing blocks 31-1, 31-2, and data path switches (2) 33-1, 33-2 are disposed in a post stage (output side) thereof. When the order of arrangement of a port and the order of arrangement of a pit of data are uneven between ICs disposed in the preceding stage/post stage, the arrangement orders are interchanged by data path switches (1) 32-1, 32-2 or the data path switches (2) 33-1, 33-2.</p> |
