Abstract

When a firmware file whose head code indicates "0" exists in the flash memory 16, the firmware program is updated in response to the firmware operation by the key input device 30. If the firmware up process is properly executed, the firmware up file is deleted from the flash memory 16. However, in the case where the firmware up process is not executed properly due to the interruption of the power supply during the update, the firmware up file is not deleted and remains in the flash memory 16. By the rewriting process of the head code corresponding to the firmware up operation, the head code assigned to this firmware file represents "1". Therefore, when the power is turned on again, the pump up process is executed without waiting for the pump up command. The operator can update the firm program with a simple operation.

Description

Compound Program and Program Processing Unit {COMPLEX PROGRAM AND PROGRAM PROCESSING DEVICE}

The present invention relates to a compound program, and more particularly, to a compound program for updating a program such as firmware. The present invention also relates to a program processing apparatus, and more particularly, to a program processing apparatus that executes the above-described complex program, for example.

In updating the firmware in a conventional device of this kind, it is necessary to connect the device with a personal computer (PC) by a cable or the like and operate the application software on the PC side.

However, in the prior art, if the PC hangs up under the influence of separate application software or the power supply to the device is interrupted while transferring the firmware from the PC to the device, the firmware update fails. In this case, the operator needs to redo the firmware update operation from the beginning, which takes time.

Therefore, the main object of the present invention is to provide a composite program and a program processing apparatus capable of correctly updating a program by a simple operation.

A complex program according to the invention of the present invention is a complex program for executing a program processing apparatus having a processor and a memory, wherein the complex program includes a first program and a second program updated by update data stored in the memory. And the first program comprises: an updating step of updating the second program based on the update data; Activate the update step in response to an update command if the numerical information assigned to the update data indicates the first value, and activate the update step without waiting for the update command if the numerical information indicates the second value. An activation step; And a deletion step of deleting, by the processor, the update data from the memory after the update by the update step is completed, wherein the second program includes: an issue step of issuing the update command when an update operation is performed; And a change step of changing the numerical information from the first numerical value to the second numerical value when the update operation is performed.

The composite program includes a first program and a second program, and is executed by a program processing apparatus having a processor and a memory. The second program is updated by the update data stored in the memory. Specifically, the first program includes an update step, a first activation step, and a delete step, and the second program includes a first issue step and a change step.

If an update operation is made, an update command is issued in the first issuing step, and the numerical information assigned to the update data is changed from the first numerical value to the second numerical value in the changing step. The first activation step activates the update step in response to the update command if the numerical information assigned to the update data indicates the first value, and performs the update step without waiting for the update command if the numerical information indicates the second value. Assimilate. The update of the second program based on the update data is executed in the update step. When the update is completed, the update data stored in the second memory is deleted in the delete step.

Therefore, when update data to which numeric information indicating the first numerical value is assigned exists in the memory, the second program is updated in response to the update operation. If the update process is performed properly, the update data is deleted from the memory. However, if the update process is not executed properly due to the interruption of power during the update, the update data is not deleted but remains in the memory. The numerical information assigned to this update data represents a 2nd numerical value. When the power is turned on again, the update process is executed without waiting for the update command. In this way, the operator can update the second program with a simple operation.

The composite program according to the invention of claim 2 is dependent on claim 1, and the second program further causes the processor to execute a determination step of determining whether the update data is legitimate data when the update operation is performed. The step issues the update command when the determination result of the determination step is positive, and the update step changes the numerical information when the determination result of the determination step is positive.

That is, if the update data stored in the memory is valid data, an update command is issued and the numerical information is changed from the first numerical value to the second numerical value. In other words, if the update data is invalid, the issue of the update command or the change of numerical information are not executed. Thereby, the situation where the 2nd program is updated based on the illegal update data can be avoided.

The complex program according to the invention of claim 3 is dependent on claim 2, wherein the first program further causes the processor to perform a deletion step of deleting the update data from the memory when the determination result of the determination step is negative. In this way, it is possible to avoid a state in which unjust update data remains in the memory.

The complex program according to the invention of claim 4 is dependent on claim 3, wherein the first program further executes a second activation step in the processor to activate the deletion step in response to a delete command, and the second program The processor further executes the output step of outputting a message and a second issuing step of issuing the delete command in response to the delete operation if the result of the discrimination of the discriminating step is negative.

If the update data is invalid data, a message is output. When the operator receives this message and performs the delete operation, the update data is deleted from the memory.

The complex program according to the invention of claim 5 is dependent on any one of claims 1 to 4, and the initial value of the numerical information is the first numerical value. Therefore, the first update of the second program is executed in response to the update operation.

The complex program according to the invention of claim 6 is dependent on any one of claims 1 to 5, wherein the program processing apparatus further includes output means for outputting a plurality of menu items, and the second program is updated in the memory. If there is data, the processor further executes an additional step of adding a specific item to the plurality of menu items.

Therefore, when the update data exists in the memory, the specific item is output by the output means. The operator can recognize the presence of update data by the output of this particular item.

The complex program according to the invention of claim 7 depends on any one of claims 1 to 6, wherein the first program is a boot program, and the second program is a firm program. The second program is started by the first program.

A program processing apparatus according to the invention of claim 8, further comprising: a processor that executes processing according to the first program and the second program; And a memory for storing update data for updating the second program, wherein the first program comprises: an update step of updating the second program based on the update data; Activate the update step in response to an update command if the numerical information assigned to the update step indicates a first value, and activate the update step without waiting for the update command if the numerical information indicates a second value. A first activation step; And a deletion step of deleting the update data from the memory after the update by the update step is completed, wherein the second program comprises: a first issuing step of issuing the update command when an update operation is performed; And a changing step of changing the numerical information from the first numerical value to the second numerical value when the update operation is performed.

As in claim 1, when update data to which numeric information indicating the first numerical value is assigned exists in the memory, the second program is updated in response to the update operation. If the update process is appropriately executed, the update data is deleted from the memory. However, if the update process is not executed properly due to the interruption of power during the update, the update data is not deleted but remains in the memory. The numerical information assigned to this update data represents a 2nd numerical value. When the power is turned on again, the update process is executed without waiting for the update command. In this way, the operator can update the second program with a simple operation.

According to the present invention, when update data to which numeric information indicating the first numerical value is assigned exists in the memory, the second program is updated in response to the update operation. If the update process is performed properly, the update data is deleted from the memory. However, if the update process is not executed properly due to the interruption of power during the update, the update data is not deleted but remains in the memory. The numerical information assigned to this update data represents a 2nd numerical value. When the power is turned on again, the update process is executed without waiting for the update command. In this way, the operator can update the second program with a simple operation.

The above and other objects, features, and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

Referring to Fig. 1, the IC recorder 10 of this embodiment has an audio reproduction function, an audio recording function, a microphone function and an external storage function. The audio reproduction function and the audio recording function are functions realized by the IC recorder 10 alone, and the microphone function and the external storage function are functions realized by the IC recorder 10 and the PC 40.

When the audio reproduction function is selected by the key input device 30, the CPU 14 sets the DSP (digital signal processor) 24 to the reproduction mode, and the DSP stores the audio file stored in the NAND type flash memory 16. Send to (24). The DSP 24 decodes the audio data included in the sent audio file and outputs the decoded audio signal from the speaker 26.

When the audio recording function is selected by the key input device 30, the CPU 14 sets the DSP 24 to the recording mode. The DSP 24 encodes the audio signal received from the microphone 28 and sends the encoded audio data to the CPU 14. The CPU 14 creates an audio file containing the sent audio data on the flash memory 16.

When the microphone function is selected by the key input device 30 while the IC recorder 10 is connected to the PC 40 by the USB controller 12, the CPU 14 sets the DSP 24 to the microphone mode. . The DSP 24 encodes the audio signal received from the microphone 28 and sends the encoded audio data to the CPU 14. The CPU 14 outputs the sent audio data to the PC 40 via the USB controller 12.

When the external storage function is selected by the key input device 30 while the IC recorder 10 is connected to the PC 40 by the USB controller 12, the CPU 14 requests an access from the PC 40. The flash memory 16 is accessed accordingly. If the access request requires the writing of a file into the flash memory 16, the CPU 14 writes the file simultaneously given from the PC 40 into the flash memory 16. If the access request requires reading of a file from the flash memory 16, the CPU 14 reads a desired file from the flash memory 16, and transfers the read file to the PC 40.

Regardless of the selection of the functions described above, the CPU 14 sets a plurality of menu items in the manner shown in FIG. 2 in the register 22r formed in the RAM 22. According to Fig. 2, "File Division", "Recording Mode", "Recording Sensitivity", "BEEP Setting", "VAS Setting", "Calendar Setting", "Timer Setting", "USB Microphone Setting", "Format" and The item of "contrast" is set. The CPU 14 scrolls these menu items on the LCD 20.

There is also a firmware file in one file transferred from the PC 40 to the flash memory 16. This file is a file for updating the firmware program (firmware) stored in the firm program area 18fm of the NOR type flash memory 18. In the case where this firmware file is stored in the flash memory 16, an item " firm up " is added to the register 22r, which is also displayed on the LCD 20.

When the power is turned on, the CPU 14 processes the flowchart shown in FIG. 3 in accordance with the boot program stored in the boot program area 18bt of the flash memory 18. Moreover, when the firm program of the firm program area 18fm is started by this boot program, the flowchart shown in FIG. 4 is processed according to this firm program.

First, referring to FIG. 3, in step S1, it is determined whether or not the firmware up file is stored in the flash memory 16. If NO, the process is executed through the startup process of step S3. If YES, the flow advances to step S5 to issue a first notification that notifies that the firmware file exists. In step S7, it is determined whether or not the head code of the firmware file is "1". If YES, the firmware processing is performed in step S15. As a result, the firm program stored in the firm program area 18fm is updated by the firm program stored in the firmup file. When the pumping-up process is completed, the pump-up file stored in the flash memory 16 is deleted in step S17, and a second notification is issued which is a notification that the pump-up file has been deleted. The process ends after the issuance of the second notification.

If NO is determined in step S7, the start process is executed in step S9. In step S11, it is determined whether there is a pump-up command, and in step S13, it is determined whether or not there is a delete command. In the case where the pump-up instruction is issued, the process proceeds from step S11 to step S15, and in the case where the delete instruction is issued, the process proceeds from step S13 to step S17. If neither command is issued, the processing of steps S11 and S13 is repeated.

The firm program is started by the start process of step S3 or S9 shown in FIG. Thus, the process according to the flowchart shown in FIG. 4 is started.

First, an initialization process is executed in step S21. Thereby, eleven menu items shown in FIG. 2 are set in the register 22r, and the menu items are displayed on the LCD 20. FIG. In step S23, it is determined whether or not the first notification is issued. If NO is determined, the process proceeds directly to step S27. If YES is determined, the process proceeds to step S25 to step S27. In step S25, the "pump up" item is added to the register 22r in the manner shown in FIG. For this reason, "firm up" is also added to the menu item displayed on the LCD 20.

In step S27, it is determined whether the operation of selecting "pump up" of the register 22r, that is, a pump up operation has been performed. If NO is determined here, the corresponding process is executed in step S29. If an item other than " firm up " set in the register 22r is selected, processing corresponding to the selected item is executed here. When the processing is completed, the process returns to step S27.

In the case of performing the firmware up operation, the flow advances to step S31 to detect the header value of the firmware file from the flash memory 16. In step S33, it is determined whether the detected header value is valid. If it is determined to be legitimate, a pump-up instruction is issued in step S35, and the head code of this pump-up file is changed from "0" to "1" in step S37 and recorded. On the other hand, if it is determined that the header value is invalid, an error message is output in step S39. On the other hand, if a delete operation is made, it is determined as "Yes" in step S41, and a delete command is issued in step S43.

When the process of step S37 or S43 is completed, the presence or absence of a 2nd notification is determined by step S45. If YES is determined, the item " firm up " is deleted from the register 22r in step S47, and then the flow returns to step S27. By the process of step S47, the item "firm-up" on the LCD 20 is also deleted.

As can be seen from the above description, when the firmware file having the leading code " 0 " is present in the flash memory 16, the firmware program is updated in response to the firmware operation by the key input device 30 (S27, S35, S15). If the update process, i.e., the firmware up process is properly executed, the firmware up file is deleted from the flash memory 16 (S17). However, in the case where the firmware up process is not properly executed due to the interruption of the power supply during the update, the firmware up file is not deleted and remains in the flash memory 16. By the rewriting process (S37) of the head code corresponding to the firmware up operation, the head code assigned to this firmware file indicates "1". Therefore, when the power is turned on again, the pump up process is executed without waiting for the pump up command (S7, S15). In this way, the operator can update the firm program with a simple operation.

According to the present invention, it is possible to implement a complex program and a program processing apparatus capable of correctly updating a program with a simple operation.
