DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dictionary information resident access device for accessing various dictionary information stored in an external storage device in an internal storage device in a computer system.

Generally, in a computer system, various dictionary information is often stored in an external storage device such as a magnetic disk device due to a limitation of a memory capacity of an internal storage device.

However, when the dictionary information is stored in the external storage device, there is a problem that the access time of the dictionary information becomes long because the operation speed of the external storage device is low.

Therefore, when dictionary information is stored in an external storage device, a measure for accessing the dictionary information at high speed is desired.

[0005]

2. Description of the Related Art To meet this demand, conventionally, dictionary information is temporarily transferred from an external storage device to an internal storage device of the system, and is accessed while resident in the internal storage device. I have.

FIG. 5 shows the configuration of a conventional dictionary information resident access device for performing such resident access.

In FIG. 1, reference numeral 1 denotes an external storage device provided outside the system for storing various dictionary information.

[0008] 2 is an internal storage device of the system,
This is a dictionary information management area provided for managing dictionary information.

In the dictionary information management area 2, a dictionary information storage area 3 for storing dictionary information read from the external storage device 1 is secured.

Reference numeral 4 denotes a dictionary information resident control unit for transferring dictionary information from the external storage device 1 to the dictionary information storage area 3.

The dictionary information resident control unit 4 transfers the dictionary information only when the dictionary information storage area 3 has a free space capable of storing all dictionary information, and when the free space is smaller than the dictionary information amount. , Do not transfer.

Reference numeral 5 denotes a dictionary access control unit that can selectively access the dictionary information storage area 3 and the external storage device 1.

The dictionary access control unit 5 accesses the dictionary information storage area 3 when dictionary information is resident in the dictionary information storage area 3 and accesses the external storage device 1 when dictionary information is not resident. It is supposed to.

According to such a configuration, the dictionary information can be accessed not from the external storage device 1 but from the internal storage device, so that the dictionary information can be accessed at high speed.

However, the conventional dictionary information resident access device does not transfer the dictionary information when there is no free space in the dictionary information storage area 3 where all the dictionary information can reside.

For this reason, in such a case, there is a problem that, although there is a free space in the dictionary information storage area 3, this free space cannot be used effectively.

In order to solve this problem, the storage capacity of the internal storage device is increased to increase the storage capacity of the dictionary information storage area 3, or the storage capacity of the dictionary information storage area 3 is kept unchanged. A method of increasing the occupancy of the storage area 3 can be considered.

However, in the former method, there is a new problem that the size of the system becomes large and the system becomes expensive.

In the latter method, there is a new problem that the number of operation programs and the like must be reduced.

[0020]

As described above, the conventional dictionary information resident access device has the dictionary information storage area 3
The dictionary information is made resident only when the free space is larger than the dictionary information amount. If the dictionary information amount is larger than the free space, even if there is free space, this should be used effectively. There was a problem that can not be.

Therefore, the present invention controls the resident amount of dictionary information according to the free space, so that even if the dictionary information amount is larger than the free space, the dictionary can effectively utilize the free space. It is intended to provide an information resident access device.

[0022]

FIG. 1 is a block diagram showing the principle configuration of the present invention.

In the figure, reference numeral 11 denotes an external storage means provided outside the system and for storing dictionary information.

Reference numeral 12 denotes an internal storage unit provided inside the system for storing the dictionary information read from the external storage unit 11.

Reference numeral 13 denotes a free space determining means for determining the free space of the internal storage means 12.

Reference numeral 14 denotes dictionary information transfer means for transferring dictionary information for the free space determined by the free space determination means 13 from the external storage means 11 to the internal storage means 12.

Reference numeral 15 denotes an access unit which can selectively access the external storage unit 11 and the internal storage unit 12.

[0028]

According to the above arrangement, the free space determination means 13 determines the free space in the internal storage means 12, and the transfer amount of the dictionary information is controlled based on the result of this determination.

Thus, the resident of the dictionary information is made according to the free space of the internal storage means 12. Therefore, even when the amount of dictionary information is larger than the free space of the internal storage means 12, Free space can be used effectively.

Further, according to such a configuration, even when the amount of dictionary information is larger than the free space of the internal storage unit 12, some of the dictionary information is stored in the internal storage unit 12.
Therefore, the access time of the dictionary information can be reduced as compared with the case where all dictionary information is accessed from the external storage unit 11 as in the related art.

[0031]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of one embodiment of the present invention.

In FIG. 1, reference numeral 21 denotes an external storage device provided outside the system for storing dictionary information.

Reference numeral 22 denotes a dictionary information management area provided in the internal storage device of the system.

The dictionary information management area 22 has a dictionary information storage area 23 and a resident information storage area 24.

Here, the dictionary information storage area 23 is an area for storing dictionary information read from the external storage device 21.

The resident information storage area 24 is an area for storing a range of dictionary information resident in the dictionary information storage area 23.

The reference numeral 25 designates the free space of the dictionary information storage area 23, and the dictionary information corresponding to the free space is stored in the external storage device 2.
1 is a dictionary information resident control unit that transfers the dictionary information to the dictionary information storage area 23.

26, when a request to release the dictionary information storage area 23 is made, that is, when the dictionary information resident in the dictionary information storage area 23 becomes unnecessary, the dictionary information storage area 23 is opened. Is a memory release control unit.

Reference numeral 27 denotes a resident information rewriting control unit for rewriting the storage contents of the resident information storage area 24 based on the transfer process of the dictionary information resident control unit 25 and the release process of the memory release control unit 26.

Reference numeral 28 denotes an external storage device 21 and a dictionary information storage area 23 based on the storage contents of the resident information storage area 24.
Is a dictionary access control unit for selectively accessing.

In the above configuration, the resident processing of the dictionary information and the memory release processing will be described first with reference to the flowchart of FIG.

In the system, when any processing request occurs, it is determined whether the request is a resident request for dictionary information or a memory release request (step S1). This determination is made, for example, by a control unit (not shown) that controls the system.

If the request is a request for resident dictionary information, the dictionary information resident control unit 25 determines the free space in the dictionary information storage area 23 (step S2).

This determination may be made for the entire system or for each terminal in the system.

Next, the dictionary information resident control unit 25 transfers the dictionary information from the external storage device 21 to the dictionary information storage area 23 (step S3). This transfer is performed in a predetermined block unit. The transfer block will be described later in detail.

When the transfer of the dictionary information for one block is completed, the resident information rewriting control unit 27 writes the range of the resident dictionary information in the resident information storage area 24 by the transfer processing in step S3 (step S4).

When the writing is completed, it is determined whether or not there is an empty area in the dictionary information storage area 23 (step S5).

If there is a free area, the process returns to step S3,
The processing described above is performed again. In contrast,
If there is no free area, the resident process ends.

If it is determined in step S1 that the request is a memory release request, the memory release control unit 26
As a result, the opening process of the dictionary information storage area 23 is executed (step S6).

Thereafter, based on the result of this processing, the resident information rewriting control unit 27 rewrites the storage contents of the resident information storage area 24.

The above is the contents of the resident processing of the dictionary information and the processing of releasing the memory. Next, the dictionary information access processing will be described.

This process is executed by the dictionary access control unit 28. In this case, the dictionary access control unit 28
First, based on the contents stored in the resident information storage area 24, the dictionary information to be accessed is stored in the dictionary information storage area 23.
It is determined whether or not it is resident.

If the target dictionary information is resident in the dictionary information storage area 23, the dictionary access control unit 28 accesses the dictionary information storage area 23 and
3 to read out dictionary information.

On the other hand, if the target dictionary information is not resident in the dictionary information storage area 23, the external storage device 21 is accessed and the dictionary information is read from the external storage device 21.

The above is the access processing of the dictionary information. Next, the transfer block of dictionary information will be described with reference to FIG.

FIG. 4 is a diagram showing an example of the structure of dictionary information.

The illustrated dictionary information includes an index file, information on read data, and information on conversion data.

Normally, only the index file is resident in the dictionary information storage area 23, and the information of the read data and the information of the conversion data are stored in the external storage device 21.

Therefore, usually, every time a dictionary is searched,
The external storage device 21 will be accessed.

On the other hand, in this embodiment, the information of the read data and the information of the converted data are each made into one block, and the resident data is arranged in the order of the information of the read data and the information of the converted data according to the free space. Can be

In the release processing in step S6 in FIG. 3, a part other than the index file may be released, or the part including this part may be released.

According to this embodiment described in detail above, the following effects can be obtained.

(1) The free space in the dictionary information storage area 23 is determined, and the dictionary information corresponding to the determined free space is made resident. Therefore, even if the dictionary information amount is larger than the free space, The capacity can be used effectively.

As a result, even when the amount of dictionary information is larger than the free space, some of the dictionary information can be read out by accessing the dictionary information storage area 23. The access speed of the dictionary information can be increased as compared with the case where the information is read out by accessing the external storage device 21.

(2) Even though the dictionary information is variably resident, the area used by other programs or the like is not pressed.

That is, a method of variably resident dictionary information has been used in the past.

However, in the past, irrespective of the free space, a frequently used word, a registered word, or the like is resident, so that an area used by another program or the like may be squeezed.

On the other hand, in this embodiment, the dictionary information is made resident based on the free space, so that the area used by other programs or the like is not pressed.

(3) The range of the dictionary information resident in the dictionary information storage area 23 is stored in the resident information storage area 24, and based on the stored contents, the external storage device 21 and the dictionary information storage area 23 are stored. Is selectively accessed, so that high-speed access can be achieved even when the external storage device 21 must be accessed.

That is, in the case where the resident range of the dictionary information is not managed, the dictionary access control unit 28 first accesses the dictionary information storage area 23, and the target dictionary information is stored in the dictionary information storage area 23. If not, the step of accessing the external storage device 21 must be taken for the first time.

However, in such a configuration, the access time of the external storage device 21 is lengthened by the time of accessing the dictionary information storage area 23.

On the other hand, in this embodiment, the resident range of the dictionary information is managed. Therefore, only by confirming the management contents, is the target dictionary information resident in the dictionary information storage area 23? Can be determined.

Thus, if the target dictionary information is not in the dictionary information storage area 23, the dictionary information storage area 2
3, the external storage device 21 can be directly accessed. Therefore, the access time of the dictionary information from the external storage device 21 can be reduced.

As described above, one embodiment of the present invention has been described in detail, but the present invention is not limited to such an embodiment.

For example, in the above embodiment, the case where the resident range of the dictionary information is managed is described. However, the present invention may not perform this management.

Even in such a configuration, the dictionary information storage area 2
3, the access time of the dictionary information can be shortened as compared with the related art because the free space of No. 3 can be effectively used.

In addition, it goes without saying that the present invention can be variously modified and implemented without departing from the scope of the invention.

[0079]

As described above, according to the present invention, by controlling the resident amount of dictionary information in accordance with the free space, even if the dictionary information amount is larger than the free space,
It is possible to provide a dictionary information resident access device capable of effectively utilizing an empty area.
