<p><P>PROBLEM TO BE SOLVED: To provide a technology for constructing a highly versatile control system in an electronic appliance whose operation is controlled by a processor executes a prescribed control program. <P>SOLUTION: When the power source of electronic equipment 1 is inputted, a CPU core 101 executes a boot program stored in a boot ROM 103. An initialization program for initializing an RAM controller 104 stored in a flash ROM 112 is transferred to an SRAM 102, and executed by a boot program. Thus, an RAM controller 104 is initialized so as to be fitted to the type or size of an SDRAM 111, and put into such a state that the SDRAM 111 is accessible. Afterwards, a control program stored in a flash ROM 112 as compressed data is extended and restored on the SDRAM 111, and the restored control program is executed, so that a normal operating state can be set. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
