<P>PROBLEM TO BE SOLVED: To provide a core monitoring device capable of determining a core causing an abnormality while suppressing an increase in software load in a multi-core icon. <P>SOLUTION: A core monitoring device 17 accepts notifications from a plurality of cores at a common cycle and comprises: core identification numeric value generation means 31 that generates a core-specific core identification numeric value (for example, a counter value×ID) for each core when receiving notifications from the cores; total value calculation means 32 that calculates a total value of the core identification numeric values of the plurality of cores; total value storage means 36 that stores the last calculated total value; first difference calculation means 33 that calculates a first difference which is the difference between the total value calculated by the total value calculation means and the total value stored by the total value storage means; first difference storage means 37 that stores the first difference; and second difference calculation means 34 that calculates a second difference which is the difference between the first difference calculated by the first difference calculation means and the first difference stored by the first difference storage means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
