PROBLEM TO BE SOLVED: To efficiently perform a debug work at a low cost without introducing an externally attached debug device. SOLUTION: A memory write request of access address information for debug is issued to a memory controller 15 according to a DMA request from a DMAC. Namely, '(2) generation of address information' is performed before '(5) generation of an original read request' and '(3) generation of a write request of address information' is performed, to be outputted to the memory controller 15 in the memory read request of the DMA. In the memory write request of the DMA, 'generation of address information and synthesis with write data' are performed and '(3) generation of the write request' is performed, to be outputted to the memory controller 15.
