PROBLEM TO BE SOLVED: To enable a single program to deal with multiple system configurations. SOLUTION: When jumped to a main body of a bootstrap, initialization for a CPU configuration and a timer and the initialization for a data cache, and the like, are performed. On a cache RAM, when a process is not executed or when the process is executed under an external mode or a state without ROM, the process is jumped to the cache RAM area after the data are copied from the ROM to the RAM. After that, the initialization for a stack, setting up an interrupt vector, the initialization for a beep, and the like, are sequentially performed. The method can be applied to a device for developing a system LSI, and the like. COPYRIGHT: (C)2005,JPO&NCIPI
