Software reverse engineering in embedded system is not convenient than it on the PC. There are many debugging and analysis software on the PC. In embedded systems, due to the diversity types of processors, it is difficult to make software tools using anywhere. However, the diversity types of processors also provide us with convenience.

In order to compensate for functional defects or add new features of an embedded product, the designer need to continuously update the system program. With the development of network technology, the end-user can download the update program through the network and complete the update process. But for the unattended equipments, they are often used of automatic remote update. On-line programming function...
Boundary-scan technology is a popular design-for-test technology, which is used by some embedded chips by means of embedding special boundary scan cells inside the circuits. It allows the debugger to talk via a JTAG port directly to the IC's core. As more and more chips using the JTAG interface, the application of JTAG emulator becomes frequent. Commercial JTAG emulators using parallel port on the...
