Abstract

PURPOSE: To facilitate both the program debug and the adjustment of the system side, by incorporating the control part possessing the console function and the RAM substituting the ROM of the system side and then carrying out the switching between the ROM of the system side and the incorporated RAM.
CONSTITUTION: Control memory 12 storing firmware FW possessing the console function, control part main body 13 which controls the inside of the device based on the FW, system service-use RAM11 which substitutes the ROM at the side of system 1, and various function control part 16 including the switch controlled by the FW, the display circuit and others are installed to system support device 2. By the signal sent from main body 13, no access is given to the ROM area of the system 1 side but RAM11 is selected. Thus the debug is possible easily for the system ROM. And loader device 15 is incorporated, and as a result the system data is stored in RAM11 to secure the working. Accordingly, both the development and adjustment can be facilitated for the small-size device such as the POS terminal or the like.
