<P>PROBLEM TO BE SOLVED: To provide a memory monitoring circuit, an information processing apparatus and a memory monitoring method that implement a high monitoring capability. <P>SOLUTION: The information processing apparatus 10 has a main memory 2 to be monitored, a CPU 1 for executing programs stored in the main memory 2, the memory monitoring circuit 4 for monitoring the main memory 2 for anomalies, a temporary memory 5 for temporarily swapping data stored in the main memory 2, and a bus arbitration part 3 for disabling the CPU 1 from accessing the main memory 2 and enabling the memory monitoring circuit 4 to access the main memory 2 during the monitoring of the main memory 2. The memory monitoring part 4 regards a part or all of the data in the main memory 2 as a monitored area, swaps out the data in the monitored area into the temporary memory 5, and tests the monitored area. <P>COPYRIGHT: (C)2009,JPO&INPIT |
