<1. Configuration>
FIG. 1 is a block diagram showing a schematic configuration of a communication terminal apparatus 1 according to an embodiment of the present invention. The communication terminal device 1 is configured as a multifunction peripheral (MFP) having a plurality of functions such as a facsimile function, a scanner function, a printer function, and a copy function.

  Among these, the facsimile function inputs image data to be transmitted, and is a destination as an external terminal specified by “phone number” or “e-mail address” (hereinafter collectively referred to as “destination information”). This function transmits the image data to the apparatus. When the “telephone number” is set as the data transmission destination, the communication terminal device 1 functions as a G3 facsimile device using the public switched telephone network (PSTN) 91. On the other hand, when “e-mail address” is set as the data transmission destination, the communication terminal device 1 functions as an Internet facsimile machine using the Internet 93 (and the LAN 92).

  As shown in FIG. 1, the communication terminal device 1 includes a main control unit (CPU) 2 for controlling the entire device. Each processing unit of the communication terminal device 1 is electrically connected to the main control unit 2 via the bus line 10. As a result, each processing unit operates under the control of the main control unit 2 and can transmit and receive data and commands between the processing units.

  An NCU (network control circuit) 11 and a fax modem 12 are processing units that implement a communication function as a G3 facsimile apparatus. That is, the NCU 11 is a hardware circuit that performs operations such as closing and opening a DC loop of the analog public telephone exchange network 91, and connects the fax modem 12 to the public telephone exchange network 91 as necessary. The fax modem 12 modulates and demodulates image data for G3 facsimile communication. When the communication terminal device 1 functions as a G3 facsimile device, the NCU 11 and the fax modem 12 exchange image data with the counterpart device.

  The LAN interface 13 is a processing unit that implements a communication function as an Internet facsimile machine. That is, the LAN interface 13 is an interface circuit for connecting the main control unit 2 and each processing unit to the LAN 92, and performs processing such as protocol conversion.

  In addition to the communication terminal device 1, a client computer, a mail server, a router device, and the like are connected to the LAN 92. The LAN 92 is connected to the Internet 93 via a router device. With such a network configuration, the communication terminal device 1 can transmit and receive data to and from other communication terminals connected to the LAN 92 and the Internet 93. When the communication terminal device 1 functions as an Internet facsimile machine, the LAN interface 13 transmits / receives an electronic mail attached with an image mail to / from a mail server on the LAN 92. The electronic mail is further transmitted / received to / from the partner apparatus via a large number of mail servers on the LAN 92 and the Internet 93.

  The operation panel 3 is a processing unit that functions as a user interface, and includes a display unit 31 that gives various information to the user and an operation unit 32 that receives user operations. The display unit 31 is configured by a liquid crystal display having a touch panel function, and can display various types of information and accept user operations. The operation unit 32 includes various buttons such as a confirmation button, a numeric button, a one-touch button, and an abbreviated button necessary for receiving various user operations.

  The image reading unit 4 is a processing unit that scans and reads an original on a paper medium by a line sensor such as a CCD and acquires image data related to the original. The image data is acquired as, for example, black and white binary data. The image reading unit 4 realizes a scanner function and an image acquisition function in a facsimile function and a copy function.

  The printing unit 5 is a processing unit that prints image data, character strings, and the like on printing paper by an electrophotographic method or the like. The printing unit 5 realizes a printer function and an image printing function in a facsimile function and a copy function.

  The ROM 8 is a storage device that stores various data and programs. Various functions of the main control unit 2 are realized by software by performing arithmetic processing according to a program stored in the ROM 8. Various processes to be described later performed by the main control unit 2 are realized in software as described above.

  The image memory 6 is a storage device that mainly stores image data, and is composed of a volatile memory that can be read and written, such as a DRAM. Image data acquired by the image reading unit 4 and image data received by the facsimile function are stored in the image memory 6.

  The image memory 6 is connected to a built-in battery 15 so that power is supplied from the built-in battery 15 in addition to the external power supply. Each processing unit including the image memory 6 of the communication terminal device 1 is supplied with power from an external power source when the power is turned on, but is shut off from the external power source when the power is turned off. Since the image memory 6 is composed of a volatile memory, the stored contents are erased without being retained unless power is supplied. For this reason, in the communication terminal device 1, the built-in battery 15 is connected to the image memory 6 so that the stored contents of the image memory 6 can be retained for a certain period even when the power is turned off. The built-in battery 15 is composed of a secondary battery that is charged when the power is turned on, and the stored contents of the image memory 6 can be maintained for about two days in a fully charged state. The built-in battery 15 may be a primary battery. The battery voltage e of the built-in battery 15 can be detected by the voltmeter 14, and the detected battery voltage e is input to the main control unit 2.

  The phone book memory 7 is a storage device that stores the phone book data 71, and is composed of a non-volatile memory capable of both reading and writing such as a flash memory and an MRAM. Since the telephone directory memory 7 is a non-volatile memory, the stored contents are not erased even when the power is turned off.

<2. Phonebook data>
The phone book data 71 is data used in the “phone book function” including the “one-touch dial function” and the “abbreviated dial function” of the communication terminal device 1, and a plurality of destinations that are candidates for data transmission destinations of the facsimile function. Information is registered.

  The “phone book function” is a function for calling destination information corresponding to a user operation in the operation unit 32 from the phone book data 71 and setting the called destination information as a data transmission destination when transmitting image data in the facsimile function. It is. In the “one-touch dial function”, the destination information can be called by pressing the one-touch button once. On the other hand, in the “abbreviated dial function”, the destination information can be called by a combination operation of pressing the abbreviated button and inputting an abbreviated number of a predetermined number of digits (for example, 3 digits) using the numeric buttons.

  In the phone book data 71, one destination information is associated with one one-touch button or one abbreviated number. FIG. 2 is a diagram illustrating an example of the phone book data 71. As shown in the figure, the phone book data 71 has a table format composed of a plurality of fields (columns) respectively corresponding to items of “function”, “call operation”, “destination information”, and “destination name”. . The content related to one destination information is registered as one record (row). Hereinafter, each record R of the telephone directory data 71 is referred to as a “destination record” R.

  The “function” field indicates whether the destination record R is related to “one-touch dial function” or “speed dial function”. In the destination record R2 related to “shortening”, “shortening” is stored.

  The “call operation” field stores the contents of a user operation for calling destination information. That is, in the “call operation” field, the identification number of the one-touch button is stored in the destination record R1 related to the “one-touch dial function”, and the abbreviated number is stored in the destination record R2 related to the “speed dial function”. Thereby, one destination information is associated with one one-touch button or one abbreviated number.

  In the “destination information” field, specific contents of the destination information, that is, “telephone number” or “e-mail address” are stored. In the “destination name” field, a name that allows a human to easily identify the external terminal specified by the destination information is stored.

<3. Register additional destination records>
The destination record of the telephone book data can be newly registered by a predetermined operation via the operation panel 3, thereby increasing the number of candidates as data transmission destinations of the facsimile function. However, the number of destination records that can be stored in the telephone directory memory 7 has an upper limit defined by the storage capacity of the telephone directory memory 7. For this reason, in the communication terminal device 1, the destination record of the phone book data can be stored not only in the phone book memory 7 but also in the image memory 6. When the destination record is additionally registered, if the phone book memory 7 has a small free space and a new destination record to be additionally stored cannot be stored in the phone book memory 7, the new destination record is stored in the image memory 6. It comes to memorize.

  FIG. 3 is a diagram illustrating a flow of a record registration process that is a process for additionally registering a destination record. This record registration process is performed under the control of the main control unit 2 in response to a predetermined user operation via the operation panel 3. Hereinafter, the record registration process will be described with reference to FIG.

  First, a screen that prompts input of the contents of each item related to a new destination record to be additionally registered is displayed on the display unit 31. While referring to this screen, the user operates the display unit 31 as the operation unit 32 or the touch panel, so that each item of “function”, “call operation”, “destination information”, and “destination name” related to the new destination record is displayed. The contents can be input (step S11).

  The user can edit the content of each item until the confirm button on the operation unit 32 is pressed (during No in step S12). However, if the user gives an instruction to cancel registration before pressing the confirm button ( It is also possible to end the record registration process at step S13.

  After the contents of each item relating to the new destination record are input, when the confirm button is pressed (Yes in step S12), the contents of each input item are received by the main control unit 2 and confirmed. The

  Next, whether or not the new address record can be stored in the phone book memory 7 in order to determine in which of the phone book memory 7 and the image memory 6 the new address record is stored by the main control unit 2. Is judged.

  That is, the number of destination records registered in the phone book memory 7 at that time (hereinafter referred to as “record registration number”, symbol n is used) and the upper limit number of destination records that can be stored in the phone book memory 7 (Hereinafter referred to as “record upper limit number”, symbol N is used) is compared, and it is determined whether or not the record registration number n is less than the record upper limit number N. The record upper limit number N is stored in advance in the ROM 8 or the like. If the record registration number n is less than the record upper limit number N, the destination record can be additionally stored in the phone book memory 7, and conversely, if the record registration number n is not less than the record upper limit number N, the phone book memory 7 is stored. It becomes impossible to additionally store the destination record (step S14).

  Here, the record registration number n corresponds to the use data amount of the telephone directory memory 7, and the record upper limit number N corresponds to the entire storage capacity of the telephone directory memory 7. Therefore, the determination in step S14 substantially corresponds to determining whether or not the free space in the telephone directory memory 7 is equal to or greater than a predetermined reference amount (storage capacity for one record).

  When the record registration number n is less than the record upper limit number N (when the free space in the phone book memory 7 is equal to or larger than the reference amount) (Yes in step S14), the destination record can be additionally stored in the phone book memory 7. A new destination record is stored in the telephone directory memory 7 (step S19).

  On the other hand, when the record registration number n is not less than the record upper limit number N (when the free space in the phone book memory 7 is smaller than the reference amount) (No in step S14), the destination record cannot be additionally stored in the phone book memory 7. Therefore, the subsequent processing is performed on the assumption that a new destination record is stored in the image memory 6.

  First, prior to storing the destination record, an inquiry to the user as to whether or not storage of the destination record in the image memory 6 is permitted is made via the display unit 31. Since the image memory 6 is a volatile memory, the destination record stored in the image memory 6 is more likely to be erased than the destination record stored in the telephone directory memory 7. Therefore, a new destination record is stored in the image memory 6 after obtaining a storage permission from the user.

  When the storage permission is not given by the user (No in step S15), the record registration process ends.

  On the other hand, when the storage permission is granted (Yes in step S15), a new destination record is stored in the image memory 6. Since the image memory 6 is mainly a memory for storing image data, as shown in FIG. 4, when no destination record is stored in the image memory 6, all the storage areas store the image data. Is assigned to the image storage area 61. For this reason, when the destination record is stored in the image memory 6 for the first time, a part of the image storage area 61 is changed and, as shown in FIG. Newly secured. Further, when the destination record is additionally stored in the image memory 6, a part of the image storage area 61 is changed, and the destination storage area 62 is additionally secured. The capacity secured at one time as the destination storage area 62 is a capacity capable of storing one destination record to be registered. Such a change of the storage area in the image memory 6 is performed by the main control unit 2. When the destination storage area 62 is secured, a new destination record is stored in the destination storage area 62 (step S16).

  When the destination record is stored in the image memory 6 for the first time, a storage flag indicating that a part of the destination record of the phone book data is stored in the image memory 6 is turned on. The data indicating the storage flag is stored in the phone book memory 7 but is 1-bit data, and therefore does not significantly affect the amount of data used in the phone book memory 7.

  When a new destination record is stored in the image memory 6, an inquiry to the user as to whether or not to print a list of destination records stored in the image memory 6 is made via the display unit 31 ( Step S17). When the user gives an instruction to print, all the destination records stored in the image memory 6 are printed as a list on the printing paper by the printing unit 5. By printing the list of destination records stored in the image memory 6 in this way, the contents of the destination records can be confirmed afterwards even when the destination records are deleted from the image memory 6. (Step S18).

  As described above, when one destination record is stored, an inquiry as to whether or not to register the next destination record is made through the display unit 31 (step S20). If the next destination record is additionally registered, the process returns to step S11. If the next destination record is not additionally registered, the record registration process ends.

  As described above, in the communication terminal device 1, the destination record of the phone book data can be stored not only in the phone book memory 7 but also in the image memory 6, so that it can be registered without a large cost increase. The number of destination information can be increased.

  In the above description, the determinations in steps S15 and S17 are determined by inquiring the user at that time, but may be determined based on setting information preset by the user.

<4. Input of image data>
In this way, in the communication terminal device 1, it is possible to store the destination record of the phone book data in the image memory 6, but the image memory 6 is originally for storing image data. Therefore, when inputting image data by the facsimile function, there may be a scene where it is desired to store the image data even if the destination record in the image memory 6 is deleted.

  For this reason, in the communication terminal device 1, the specific condition that “the destination record is stored in the image memory 6, and the free space of the image memory 6 is reduced when inputting the image data to be stored in the image memory 6”. Below, the user sets in advance as “data priority setting” whether to perform the operation of preferentially storing the image data by deleting the destination record or the operation of maintaining the storage of the destination record. It is possible.

  In the “data priority setting”, either “image data priority” or “destination record priority” is set. “Image data priority” is a setting for preferentially storing image data under the specific condition, and “destination record priority” is a setting for continuing to store the destination record under the specific condition.

  When image data is preferentially stored, at least a part of the destination storage area 62 is changed to the image storage area 61, and the image data is stored in the image storage area 61. When the destination storage area 62 is changed to the image storage area 61 in this way, the destination record stored in the destination storage area 62 that is the change target is deleted. The “data priority setting” corresponds to a setting indicating whether or not the change of the destination storage area 62 to the image storage area 61 is permitted under the specific condition.

  When inputting image data, an operation according to “data priority setting” is performed. Hereinafter, processing when inputting image data in this way will be described. FIG. 6 is a diagram showing a flow of reception processing when image data is received by the G3 facsimile function. This process is performed under the control of the main control unit 2.

  In the reception process, first, accumulation and storage of received image data in the image memory 6 is started (step S21). Thereafter, until reception of image data is completed (during No in step S23), the free space of the image memory 6 is monitored, and the free space is compared with a predetermined reference amount D1 (step S22). ). The reference amount D1 is stored in advance in the ROM 8 or the like. If the reception of the image data is completed while the free space of the image memory 6 is maintained at the reference amount D1 or more, the reception process is finished as it is.

  When the free space in the image memory 6 becomes smaller than the reference amount D1, next, whether the destination record is stored in the image memory 6 (step S24) or “image data priority” (step S25). Each of the three conditions is determined as to whether or not a setting for instructing printing of the list of destination records is made (step S26).

  When all of these conditions are satisfied, the process proceeds to step S27, and all destination records stored in the image memory 6 are printed as a list on the printing paper by the printing unit 5. Thereafter, the process proceeds to step S28.

  In the processing after step S28, there is a processing for deleting the destination record in the image memory 6, and at the time of step S27 when the free space of the image memory 6 becomes smaller than the reference amount D1, the probability of the deletion is high. It can be said. For this reason, the printing process in step S27 is a process in which a list of destination records stored in the image memory 6 is left in advance as a printed matter before the destination records are deleted from the image memory 6. In other words, it can be said that this printing process is a process for printing the destination information stored in the image memory 6 before changing at least a part of the destination storage area 62 to the image storage area 61. Even if the destination record is erased by such a printing process, the contents can be confirmed afterwards.

  If any of the three conditions in steps S24 to S26 is not satisfied, the printing process is not performed and the process proceeds to step S28 as it is. If the destination record is not stored in the image memory 6 in step S24, the destination record is not erased because there is no destination record to be erased in the first place. Further, in the case of “destination record priority” in step S25, since it is necessary to continue storing the destination record, the destination record is not erased. Therefore, in these cases, there is no need to perform a printing process. The setting in step S26 is a setting indicating whether or not to print a list of destination records, and is set in advance by the user. Only in the case of setting to instruct printing, the printing process is performed.

  After step S28, until the reception of the image data is completed (between No in step S33), the free space of the image memory 6 is compared with the predetermined reference amount D2 (step S28). The reference amount D2 is smaller than the reference amount D1 described above, and the case where the free space is lower than the reference amount D2 corresponds to a situation where no more image data can be stored in the image memory 6. This reference amount D2 is also stored in advance in the ROM 8 or the like. When the reception of the image data is completed while the free space of the image memory 6 is maintained at the reference amount D2 or more, the reception process is finished as it is.

  On the other hand, when the free space of the image memory 6 becomes smaller than the reference amount D2, next, whether the destination record is stored in the image memory 6 (step S29) or “image data priority” (step S30). These two conditions are determined respectively. When these two conditions are satisfied, the process proceeds to step S31, the destination storage area 62 is changed to the image storage area 61, and the destination record is deleted. Then, the image data is stored in the newly secured image storage area 61 (step S31). The storage area to be changed to the image storage area 61 may be the entire destination storage area 62 or a part thereof.

  When the destination record in the image memory 6 is erased in this manner, a message (character string) indicating that the destination record stored in the image memory 6 has been erased is subsequently printed by the printing unit 5 on the printing paper. Printed on. Since the reception process is an automatic process, the user is usually not present in the vicinity of the communication terminal device 1 during the period of the reception process. For this reason, by performing such printing, it is possible to reliably notify the user that it has been erased (step S18). After this notification, the process returns to step S28 again, and the reception process ends when the reception of the image data is completed.

  If one of the two conditions in steps S29 and S30 is not satisfied, the process proceeds to step S34 without deleting the destination record. Similar to steps S24 and S25 described above, if no destination record is stored in the image memory 6 in step S29, there is no destination record to be erased, and if “destination record priority” is selected in step S30. This is because it is necessary to maintain the storage of the destination record. In this case, since the image storage area 61 of the image memory 6 cannot be newly secured, a memory over process is performed to notify the counterpart device that the reception is impossible and disconnect the communication (step S34). The process ends.

  In this description, the reception process has been described as an example, but the same process may be performed in other processes for inputting image data. In addition, when image data is input by the image reading unit 4, for example, when image data is transmitted by a facsimile function, the user is likely to be in the vicinity of the communication terminal device 1. For this reason, in this case, the determinations in steps S25, S26, and S30 may be made by inquiring the user at that time.

  In step S32, the user indicates that the destination record stored in the image memory 6 has been erased by displaying a message on the display unit 31, lighting an operation indicator such as an LED, or generating a warning sound. May be notified.

  In the above description, notification is made immediately after the destination record is erased. However, at the time when the destination record is erased, a notification to the effect of deletion is not performed and a predetermined notification is given instead. The flag may be turned on, and the user may be notified of erasure according to the flag at a later time.

  For example, in a communication terminal device that employs a face-down method (printing paper discharging method that discharges with the printing surface facing down), printing of the image data is started each time reception of one page of image data is completed. The For this reason, if printing is performed immediately after erasing the destination record as described above, a message indicating erasure of the destination record that is not related to the print data indicating the received image data is displayed between the print sheets. The print sheets shown may be mixed. Therefore, in a communication terminal device that employs such a face-down method, it is preferable to notify the user that the destination record has been deleted after all the received image data has been printed.

  However, when the notification of the deletion of the address record is simply performed by displaying a message on the display unit 31 of the operation panel 3 instead of printing, there are few restrictions on the timing of the deletion notification. For this reason, including such a case, the actual erasure may be performed after the erasure notification is given first. In any of these modes, the erasure notification is performed along with the erasure operation.

<5. Erase confirmation process>
The destination record stored in the image memory 6 is preferably not erased even when the power is turned off. For this reason, as described above, in the communication terminal device 1, the built-in battery 15 is connected to the image memory 6, and the stored contents of the image memory 6 are maintained even when the power is turned off. However, if the battery voltage e of the built-in battery 15 becomes low when the power is turned off and the power necessary for maintaining the stored contents of the image memory 6 is not supplied, the destination record may be deleted. For this reason, in the communication terminal device 1, an erasure confirmation process for confirming whether or not the destination record has been erased is performed as one of the initialization processes performed by the control of the main control unit 2 immediately after the power is turned on. It has become.

  FIG. 7 is a diagram showing the flow of the erasure confirmation process. First, the battery voltage e of the built-in battery 15 is detected by the voltmeter 14 (step S41). Next, the detected battery voltage e is compared with a predetermined reference voltage E. The reference voltage E is at least a voltage necessary for maintaining the stored contents of the image memory 6 and is stored in advance in the ROM 8 (step S42). If battery voltage e is higher than reference voltage E (No in step S42), it is determined that storage of the destination record by image memory 6 is maintained, and the erasure confirmation process ends.

  On the other hand, when the battery voltage e is lower than the reference voltage E (Yes in step S42), the storage flag indicates whether the destination record is stored in the image memory 6 before the power is turned off. (Step S43). If the destination record is stored in the image memory 6 (Yes in step S43), it is determined that the destination record has been deleted.

  If it is determined that the destination record has been deleted, then a message indicating that the destination record in the image memory 6 has been deleted is displayed on the display unit 31, and the user is notified of this (step S44). After this notification, the erasure confirmation process ends. This notification may also be made by printing by the printing unit, turning on an operation indicator such as an LED, or generating a warning sound.

<6. Move destination record>
Since the destination record may be deleted as described above when stored in the image memory 6, it is preferable to store the destination record in the telephone directory memory 7 as much as possible. On the other hand, the number of destination records (record registration number n) stored in the telephone directory memory 7 may decrease due to deletion by a user operation or the like. Therefore, in this case, a new destination record can be stored in the telephone directory memory 7. For this reason, in the communication terminal device 1, the destination record stored in the image memory 6 can be moved and stored in the telephone directory memory 7 by the user performing a predetermined operation.

  FIG. 8 is a diagram showing a flow of a record moving process for moving a destination record stored in the image memory 6. This record movement process is performed under the control of the main control unit 2 in response to a predetermined user operation via the operation panel 3.

  First, the record registration number n is compared with the record upper limit number N (step S51). If the record registration number n is not less than the record upper limit number N (No in step S51), it is impossible to additionally store the destination record in the telephone directory memory 7. For this reason, in this case, after the notification that the movement is impossible is displayed on the display unit 31, the record movement process ends (step S55).

  On the other hand, if the record registration number n is less than the record upper limit number N (Yes in step S51), (N−n) destination records can be additionally stored in the telephone directory memory 7. Therefore, the maximum (N−n) destination records are selected as the movement target records from the destination records stored in the image memory 6. The selection of the destination record may be automatically selected by the main control unit 2 in accordance with a predetermined condition, or may be selected by the user (step S52).

  Next, the destination record selected as the movement target record is stored in the telephone directory memory 7 (step S53). At the same time, the destination record is deleted from the image memory 6 (step S54). Thereby, the movement of the destination record is completed.

  In this description, the record moving process is performed in response to a predetermined user operation. However, the record moving process is automatically performed in response to a predetermined condition being satisfied other than the user operation. May be. As this predetermined condition, for example, “when a destination record stored in the telephone book memory 7 is deleted” or “the destination record is stored in the image memory 6, which is the above specific condition, the image memory 6 When the image data to be stored is input, the free space of the image memory 6 is reduced.

  When performing the record movement process in response to the specific condition being satisfied, for example, when Yes in step S28 in FIG. 6 (when the free space of the image memory 6 becomes smaller than the reference amount D2), The record moving process shown in FIG. 8 may be performed before the determination in step S29. In this case, the notification of the impossibility of movement in step S55 may or may not be performed by printing on printing paper. Further, a notification (movement notification) indicating that the destination record has been moved is given to the user by, for example, causing the printing unit 5 to print a message on the printing paper in accordance with the movement of the destination record. You may make it perform.

  The communication terminal device that performs such processing is “the destination information is stored in the second memory, the image data to be stored in the second memory is input, and the free space in the second memory is the second reference amount. It can also be expressed as a “communication terminal device” having a moving means for moving the destination information stored in the second memory to the first memory when According to this, since the destination information is moved to the first memory, the image data can be stored in the second memory without deleting the destination information.

<7. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible.

  For example, in the above embodiment, a destination record to be additionally registered is input by a user operation via the operation panel 3. For example, it is input via a network such as a LAN or by reading a recording medium. May be.

  In the above embodiment, the number of destination records that can be stored in the image memory 6 is not limited. However, a predetermined limit such as 500 records may be provided.

  In the above embodiment, the phone book data and the destination record are commonly used for both the “one-touch dial function” and the “abbreviated dial function”, but the “one-touch dial function” and the “abbreviated dial function” There may be independent phone book data and destination records for each. In this case, a destination storage area may be secured independently for each of the “one-touch dial function” and the “abbreviated dial function”.

  Further, in the above-described embodiment, it has been described that various functions are realized in software by the arithmetic processing of the CPU according to the program. However, some of these functions are realized by an electrical hardware circuit. Also good. Conversely, some of the functions realized by the hardware circuit may be realized by software.
