Abstract
To provide a system for monitoring data transmitted between parts of an electronic machine. The system includes a mirror memory circuit that is subjected to writing and reading of data in the same manner as a memory circuit based on first data to be supplied from a memory controller to a memory circuit, and a signal sampling circuit that stores in a sampling memory circuit the first data as well as second data read out of the mirror memory circuit. The sampling memory circuit stores exact copies of the first data supplied from the memory controller to the memory circuit and exact copies of the second data supplied from the memory circuit to the memory controller. Therefore, it is possible to monitor the data transmitted between the memory controller and the memory circuit.
