PROBLEM TO BE SOLVED: To shorten a start time on the assumption of using a plurality of CPUs. SOLUTION: A program to be executed by each of first and second CPU is stored in a non-volatile memory as a compression code. When reading and decompressing the compression code from the non-volatile memory, and developing the program to a RAM in boot processing, each CPU stores a predetermined amount of compression code in a buffer memory, and when reading the next compression code from the non-volatile memory again, each CPU decompresses the compression code stored in the own region of the buffer memory when access to the non-volatile memory conflicts with the other CPU (NAND controller busy).
