Texas Instruments (TI)’s SMQ320C32x is used in various fields such as military, nuclear facilities, and aviation. However, this CPU has difficulties in compatibility such as discontinued parallel port with Computer & Emulator for Joint Test Action Group (JTAG) Cable and security & availability problem such discontinued Windows OS. For development and maintenance of devices using this CPU, JTAG connection is essential, and parallel port (LPT) connection is essential now. However, PCs with built-in parallel port are not produced. And, for connecting Programmable Logic Controller (PLC) composed of this CPU in nuclear power plants or other industrial facilities to the computer, the XDS510PP-MPSD product in Spectrum Digital Inc must be used, and it is difficult to secure it. Also, you must use Windows XP or Windows 2000 with Code Composer program provided by TI, which has security problems and has been discontinued. According to the regulatory requirements in the nuclear field, these compatibility and security issues must be resolved before use. This paper presents the world’s first solution to these difficulties. |
