BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device having a plurality of storage devices.

[0002]

2. Description of the Related Art Generally, an information processing device (computer)
Is equipped with a plurality of types of storage devices, the data input / output speeds of these storage devices are often different.
For example, if the input / output speed is extremely high, DR
There is a main memory or the like configured by AM or the like, and a medium speed one is a hard disk device. Furthermore, a floppy disk drive or the like is one that is slower. Therefore, when executing application software that frequently uses these storage devices,
Which storage device can be used is a major problem in terms of software processing efficiency. That is, when the application software uses a storage area with a certain capacity as a work area, there is no problem if the required capacity can be secured on the high-speed storage device, but if not, use only the low-speed storage device from the beginning. I had to do it.

Further, as a data management system in such an information processing apparatus, for example, in Japanese Patent Laid-Open No. 2-294854, by storing the record management information of the data file and each data record in the data file, A "data file management method" is disclosed in which it is not necessary to prepare a management file in advance, and a free area can be reduced to effectively utilize the capacity of the auxiliary storage device.

[0004]

As described above, conventionally,
There is no problem if the application software can secure the necessary storage area on the high-speed storage device, but if it cannot secure the storage area, it is obligatory to use only the low-speed storage device from the beginning. It was difficult to do at high speed. Further, in the above-mentioned "data file management method", only the method of linking (managing) data files is described, and it does not lead to speeding up of data access, and particularly the storage device is frequently used as a work area. It has been difficult to speed up processing with various application software.

Therefore, an object of the present invention is to provide an information processing apparatus capable of performing high-speed data input / output processing by efficiently utilizing a plurality of storage devices having different input / output speeds. Is to provide.

[0006]

According to a first aspect of the present invention, a plurality of storage devices having different data input / output speeds, a plurality of storage devices used by application software and means for designating the order of use are specified. Means for sequentially executing data input / output to / from a specified storage device in a specified order, and performing the data input / output by using the storage device specified by the application software in the specified order. To achieve the above objectives. According to the present invention, by providing means for setting the use priority of the storage device (area) from the application software side, it is possible to use the storage devices in order from the high speed storage device depending on the setting method. Data can be input and output at high speed.

According to a second aspect of the present invention, a plurality of storage devices having different data input / output speeds, means for measuring the input / output speeds of the plurality of storage devices in advance, and data input / output processing to / from the storage device are measured. And a means for sequentially executing from the identified high-speed storage device, and preferentially using the high-speed storage device based on the measured value of the data input / output operation speed to perform the data input / output processing. In order to achieve the above purpose. According to the present invention, the data input / output speeds of the usable storage devices are automatically measured without setting the use priority in advance from the application software side, so that the high-speed storage devices can be used sequentially. As a result, data input / output of application software can be performed at high speed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
A preferred embodiment of the present invention will be described in detail. FIG.
It is a figure showing the whole composition of the information processor concerning one embodiment of the present invention. This device includes a control unit 11 for performing processing such as management of a data area to be used, and a keyboard 12 for inputting operation information from an operator to the control unit 11.
Also, a mouse 13, a screen display unit 14 for displaying various messages from the control unit 11 to the operator, a high speed storage device 15 and a low speed storage device 16 for holding data files and program files are provided. Here, the high-speed storage device 15 is a storage device capable of high-speed data input / output, and the low-speed storage device 16 is a storage device having a relatively low-speed data input / output.

FIG. 2 is a block diagram showing various functions of the control unit 11. Data input / output target setting unit 2
Reference numeral 1 is for setting a storage device (area) and a directory which are targets of data input / output. This setting is
For example, it is performed by a method described in a setting file or a method using an environment variable provided by an operating system (OS). The following description shows an example of the setting. TEMP A: \ TEMP; B: \ TEMP DATA B: \ DATA

In this example, the variable names referred to by the application software are "TEMP" and "DATA".
"A" or "B" is set as the storage device (drive name in this case), and "\ TEMP" or "\ DATA" is defined as the directory name. In this way, it is assumed that a plurality of storage device / directory names can be defined for each variable.

The data input / output speed measurement storage unit 22 measures the input / output speed of each usable storage device (area) and stores the result. Specifically, at the time of the first execution, common test data is written to and read from each storage device, and the required time (speed) as the measurement result is recorded in a save file. The recording unit setting reference unit 13 is for setting a recording unit, and is defined by a setting file and environment variables like the data input / output target setting unit 21.

The data input / output execution unit 14 refers to the storage device and directory name set by the data input / output target setting unit 21, or the storage device and data measured / saved by the data input / output speed measurement storage unit 22. As shown in FIG. 3, it is the driver software that mediates between the OS 28 controlling the high speed storage device 15 and the low speed storage device 16 and the application software 27.

The operation of the information processing apparatus having the above configuration will be described. Here, a case where the data input / output target setting unit 21 is used will be described. FIG. 4 is a flowchart showing a procedure of processing of the data input / output execution unit 24 when writing data. First, the data input / output target setting means 11 indicates variables preset and storage target areas (data indicating a logical area and a directory name in the storage device) defined corresponding to the variables and their use order. Read and recognize the data shown (step 10
1). Next, the variable name pointing to the write target area and the data to be written are received from the application (step 102), and the data is written to the target area corresponding to the variable name (step 103). If all the data can be written normally (step 104; N), the application is notified by the normal termination code that the writing has been completed normally (step 105).

On the other hand, when a capacity shortage error occurs (step 104; Y), the following processing is performed. That is, when the area next to the area to be written is set (step 106; Y), the target area is reset to that area (step 107), and the processing from step 103 is executed again. If the next area is not set (step 106; N), the application is notified by the error end code that an error of insufficient capacity has occurred (step 108).

In step 108, when the storage unit is no longer empty and the recording unit setting reference unit 13 is set to link in a plurality of areas, the link destination ( Make sure to write the following data file storage location). An example is shown below. 100 ABCD ...... XYZ B: \ WDATA \ WO
RD1, DAT In this example, "100" is the data length, "ABCD ... XY
"Z" and "B: \ WDATA \ WORD1, DAT" indicate areas in which the next data is stored. When the setting is made so that no link is made, data is written from the beginning to the next area.

FIG. 5 is a flow chart showing the procedure of the processing of the data input / output execution unit 24 when reading data. First, as in the case of writing, referring to the data input / output target setting unit 21, the relationship between the set variable and the target area is recognized (step 201). Next, each target area is searched in the specified order to check whether or not the file specified by the application is read. This search is repeated until the specified file is found (step 2
02). When the designated file is found, the data of the file is read (step 203), and it is judged whether or not it is linked to the next data (step 20).
4). If they are linked (step 204;
Y), the area (drive name) / directory / file name of the link destination is recognized (step 205), and the process is repeated from the data reading in step 203.

The above description is for the data input / output target setting unit 21.
However, the same applies to the case where the data input / output speed measurement storage unit 22 is used (referenced). However, in this case, it is not necessary to specify a variable name corresponding to the storage device and directory name of the data input / output target when writing / reading the data, and the reference location of the storage device usage sequence is the data input / output target setting. The difference is that it is not the unit 21 but the data input / output speed measurement storage unit 22. It should be noted that the data input / output target setting unit 21 is referred to so as to recognize the storage device to be used, or the storage device to be used is determined based on the result of the automatic measurement by the data input / output speed measurement storage unit 22. Whether or not to recognize may be freely selected by the user, or may be fixed to either one.

[0019]

According to the first aspect of the present invention, means for setting the use priority of the storage device (area) from the application software side is provided, and the specified storage device is used in the specified order to obtain the data. Since input / output is performed, it is possible to sequentially use the high-speed storage devices depending on the setting method. This speeds up the execution of application software that uses the storage device.
Efficiency can be realized. In particular, the effect is great with application software that frequently uses the storage device.

According to the second aspect of the invention, since the input / output speed of the storage device is automatically identified and the storage devices are used in order from the high speed storage device, the application software that uses the storage device is executed. It is possible to save the user the trouble of designating the storage device to be used in advance in order to increase the speed and efficiency.

According to the third aspect of the present invention, since an arbitrary data file management unit can be designated, the data can be stored and recorded in the unit intended by the user.
