Abstract
There are provided a non-volatile memory in which two physical sectors have been set as areas to store a basic program, an apparatus for obtaining a new basic program from the outside, and a processor for executing an application program stored in the memory in accordance with the basic program stored in the memory. The processor allows the obtained new basic program to be stored into the physical sector which is not used to write the basic program between the two physical sectors in the memory. A new basic program is stored into the other physical sector which is not the physical sector in which the basic program has been stored at the preceding time. Upon activation, the physical sector to write the basic program is switched in accordance with whether the program is normally activated or not.
Claims14
An information processing apparatus comprising:
- storage means in which at least two memory areas have been preset;
- means for obtaining a new basic program from the outside;
- and
- executing means for executing an application program stored in said storage means in accordance with said basic program stored in said storage means,
- characterized in that said executing means allows said obtained new basic program to be stored into the memory area which is not used to write the basic program between said at least two memory areas in said storage means.
An information processing apparatus comprising:
- storage means in which at least two memory areas to store a basic program have been preset and an application program is stored;
- means for obtaining a new basic program and a new application program from an outside;
- and
- executing means for executing the application program stored in said storage means in accordance with the basic program stored in said storage means,
- characterized in that said executing means allows said new basic program obtained to be stored into the memory area which is not used to write the basic program between said at least two memory areas in said storage means and, after that, allows said new application program to be stored into the area other than the area in which said new basic program has been stored.
An information processing method characterized by comprising the steps of:
- storing a basic program into one of at least two preset memory areas and executing a stored application program in accordance with said stored basic program;
- and
- storing a new basic program obtained from an outside into the other memory area which is not used to write the basic program between said at least two memory areas.
An information processing method characterized by comprising the steps of:
- storing a basic program into one of at least two preset memory areas and executing a stored application program in accordance with said stored basic program;
- and
- storing a new basic program obtained from an outside into the other memory area which is not used to write the basic program between said at least two memory areas in said storage means and, after that, storing a new application program obtained from the outside into the area other than the area in which said new basic program has been stored.
