Abstract

An electronic device that exercises control over processes arbitrary in number for execution using a control program, including: storage means for forming each of the processes for execution by the electronic device with any of various combinations of a plurality of unit processes, creating, for each of the processes, the control program for use by the electronic device to execute the processes by a unit program for execution of the unit processes and a process step table in which an execution sequence of the unit programs is defined, storing the process step table for each of the processes, and storing the unit programs listed in each of the process step tables; and execution means for executing, in the defined execution sequence, when any predetermined one of the processes is directed, the unit programs defined in any of the process step tables stored corresponding to the directed process.

Claims

1. An electronic device that exercises control over processes arbitrary in number for execution using a control program, comprising:

storage means for forming each of the processes for execution by the electronic device with any of various combinations of a plurality of unit processes, creating, for each of the processes, the control program for use by the electronic device to execute the processes by a unit program for execution of the unit processes and a process step table in which an execution sequence of the unit programs is defined, storing the process step table for each of the processes, and storing the unit programs listed in each of the process step tables; and

execution means for executing, in the defined execution sequence, when any predetermined one of the processes is directed, the unit programs defined in any of the process step tables stored corresponding to the directed process.

2. The electronic device according to claim 1, wherein

the processes include a process of diagnosis of diagnosing whether the execution means is operating normally, or a process of readjustment of appropriately readjusting a parameter value for use when the processes are executed.

3. The electronic device according to claim 1, wherein

the processes include a process related to data reading from a disk or data recording to the disk.

4. An electronic device according to claim 1, wherein

the process step table carries therein information about, when any error is occurred during the execution of any of the unit programs that is firstly executed, any of the unit programs that is secondly executed for resetting the execution sequence to the firstly-executed unit program, and

when any error is occurred during the execution of the firstly-executed unit program, the execution means executes the secondly-executed unit program by referring to the process step table.

5. A control method of exercising control over processes arbitrary in number for execution by an electronic device using a control program, comprising the steps of:

forming, when a process command is provided for execution of any of the processes, each of the processes for execution by the electronic device with any of various combinations of a plurality of unit processes, creating, for each of the processes, the control program for use by the electronic device to execute the processes by a unit program for execution of the unit processes and a process step table in which an execution sequence of the unit programs is defined, and reading the process step table corresponding to the directed process and the unit program defined therein; and

executing the read unit program in the execution sequence defined in the read process step table.

6. A control program of exercising control over processes arbitrary in number for execution by an electronic device using a control program, comprising the steps of:

forming, when a process command is provided for execution of any of the processes, each of the processes for execution by the electronic device with any of various combinations of a plurality of unit processes, creating, for each of the processes, the control program for use by the electronic device to execute the processes by a unit program for execution of the unit processes and a process step table in which an execution sequence of the unit programs is defined, and reading the process step table corresponding to the directed process and the unit program defined therein; and

executing the read unit program in the execution sequence defined in the read process step table.

7. An electronic device that exercises control over processes arbitrary in number for execution using a control program, comprising:

a storage section forming each of the processes for execution by the electronic device with any of various combinations of a plurality of unit processes, creating, for each of the processes, the control program for use by the electronic device to execute the processes by a unit program for execution of the unit processes and a process step table in which an execution sequence of the unit programs is defined, storing the process step table for each of the processes, and storing the unit programs listed in each of the process step tables; and

an execution section executing, in the defined execution sequence, when any predetermined one of the processes is directed, the unit programs defined in any of the process step tables stored corresponding to the directed process.
