PURPOSE:To attain debugging easily by setting up a specific memory address, displaying the contents of addresses preceding to the specific address from a memory buffer storing the contents together with the current contents, and when both the contents are different each other, changing the luminance or color of a screen. CONSTITUTION:At the time of debugging, a required address in a memory space 2 is inputted from an input part 5. A control part 3 fetches the contents of the specified address of the memory from the memory space 2, accumulates the fetched contents in a memory buffer 4 and the contents of the specified address are successively displayed on a display part 6. When the preceding contents are different from the current ones, the color or luminance displayed on the display part 6 is changed by a control part 3. In the specification of the memory space 2 from the input part 5, a continuous area including a start address and an end address can be specified and random areas can be also specified. Thus, debugging work can be made efficient. |
