In a signal processing apparatus having a memory and plural blocks for accessing the memory provided in an LSI, for the ease of cause analysis in the event of a fault, a trace control block 170 is provided, and by setting from a microcomputer 110, start and end of storing of access history from the required memory access block and content of storing are controlled, and a specified region of the memory is traced. In the event of a fault, by reading out the specific tracing region in the built-in memory 160 from outside, the cause can be analyzed easily. |
