ABSTRACT:
A configurable circuit of the present invention includes a plurality of logic blocks (4), and a programmable bus which can program connections of plurality of logic blocks (4). The programmable bus includes a plurality of wires (11—x) arranged for each of signal transmission ranges corresponding to plurality of logic blocks (4), direct wire connection switch (711—x) which can program whether to directly connect or disconnect the wires between the adjacent signal transmission ranges, input selector (30—x) which can program a connection with any one of the plurality of wires, and programmable switch (40—x) which can program whether to make a connection with the wire corresponding to the adjacent signal transmission range for each of the plurality of wires. A plurality of programmable switches (40—x) are arranged for at least one of plurality of logic blocks (4).
