PURPOSE:To obtain a small-sized and inexpensive debugging device not to occupy a space by executing a division into a debugging shared processor and an operation panel device for debugging. CONSTITUTION:The debugging device is divided into a debugging shared processor (DBGPU) 20 having a microprocessor with a function to be the same as to equal to a microprocessor (MPU) 13 of a system 10 to be tested and a controller function for debugging and an operation panel device (OPPNL) 30 for debugging to execute a man machine interface control essential for debugging the system to to be tested. Consequently, both the DBGMPU 20 and OPPNL 30 can be easily, miniaturizedly and inexpensively composed. In such a way, by using the DBGMPU 20 and OPPNL 30, the small-sized and inexpensive debugging device not to occupy the space can be composed. |
