PROBLEM TO BE SOLVED: To provide a "LSI device" capable of effectively utilizing an electronic circuit of an unselected function when selecting any function from among a plurality of functions.SOLUTION: A plurality of processor cores 31 and 32 that are connected to electronic circuits 11 to 13 having a plurality of functions enable a loop back function for the electronic circuits 11 and 12 that are not selected by a selector and are not connected with an external I/O terminal to perform data communication between the cores via ports 11a, 11b, 12a, and 12b, which the electronic circuits 11 and 12 include in twos, and via a plurality of memory spaces 41 and 42 corresponding to the plurality of processor cores 31 and 32. Thus, the electronic circuits 11 and 12 that are not connected to the external I/O terminal can be also utilized for inter-core communications between the plurality of processor cores 31 and 32. |
