PURPOSE:To execute the debugging including the action of a hardware by using effectively all memories at the time of debugging the software. CONSTITUTION:When a mode selecting signal 2,400 designates the first action mode, both a memory 3-0 for tracing and a memory 3-1 for tracing are enabled, and operated as two memories to have the same writing address and the different data input. When the mode selecting signal 2,400 designates the second action mode and the next higher order bit to output through a line 5,001 of a counter 5 is '0' only the memory 3-0 for tracing is enabled and when the bit is '1' only the memory 3-1 for tracing is enabled. In the second action mode, the memory 3-0 for tracing and the memory 3-1 for tracing have the same data input 1,000 and are operated as one memory which can designate a continuous series of the different address, by a counter 5. |
