PROBLEM TO BE SOLVED: To execute a peripheral device access system without changing an existing application when environment is changed from OS unloaded to OS loaded.SOLUTION: Even after loading an OS, an existing application 2 performs call processing using processing function names ('startRead 'and 'checkReadEnd') of a driver in the case of OS unloaded in the case of data reading from a flash memory 13. According to the call processing, reading start 21, reading completion confirmation 23 of an application execution part 20 are called. Thus, the application execution part 20 calls reading start 31, the reading completion confirmation 23 of a driver 30 to make them execute access processing to a flash memory 13 while performing exclusion control using a semaphore 4 for reading. |
