Debugging method based upon memory address and its measuring instrument

TL;DR: In this paper, the execution addresses of a memory map in accordance with the reading clocks of the memory and displaying the execution address so as to visually follow up them is used for debugging.

Abstract: PURPOSE:To save time to be consumed for debugging by sequentially fetching the execution addresses of a memory map in accordance with the reading clocks of a memory and displaying the execution addresses so as to visually follow up them CONSTITUTION:A reading part 7 reads out an execution address on an address bus based upon a clock generated from a ROM 3 Namely, data existing in the address bus are extracted together with a reading instruction outputted from a CPU to the ROM 3 by using a reading clock generated from the ROM 3 as a trigger and temporarily stored in a buffer Then, a display address setting part 9 sets up a leading address and a range to be displayed based upon the reading address and detects data necessary for debugging A display correction part 11 converts the leading address set up by the setting part 9 out of the execution addresses extracted from the ROM by the reading part 7 and temporarily stored in the buffer and data in the address range so as to be visually followed up
