<P>PROBLEM TO BE SOLVED: To solve a problem of having difficulty in securing reliability of data read from a memory of a monitoring device due to an overlap of a data writing period to the memory of the monitoring device and a data reading period from the memory of the monitoring device. <P>SOLUTION: An emulator 50 is connectable between a target device 51 having a memory 53 for holding successively updated first data, and a host device 52 acquiring second data coinciding with the first data held in a first memory. The emulator 50 comprises a bus 6; a memory 2 holding the second data; an evaluation chip 1 inputting the second data successively into the memory 2 through the bus 6 according to updating of the first data; an event detecting part 9 outputting an event detection signal when the data flowing to the bus 6 meets preset event detecting conditions; and a transfer control part 8 outputting the second data from the memory 2 based on the event detection signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
