Abstract
The present invention enables program codes to be shared among processors. To prevent the debug operation of one processorfrom affecting the debug operation of the other processors, when detecting a breakpoint during execution of a program code, a debuggeror a debugger stubcontrols the execution of the program code while exchanging breakpoint informationwith the other debuggersor the other debugger stubs. Furthermore, a circuitis created which prevents the program code being carelessly rewritten due to thermal runaway, a bug, and the like of a processor, and the protection setting by the protection logicin the circuitis released only in case the processoraccesses each of a plurality of registers fromtoin specified order.
