Abstract

PURPOSE:To prevent a loading wait time from becoming long by substituting loading from an auxiliary storage device to a main storage device with loading from an IC memory when the same program or data with the auxiliary storage device are stored in the IC memory. CONSTITUTION:This system has the nonvolatile readable/writable IC memory 3, an automatic update control part 4 which performs control so that the program and data on the IC memory 3 are the same as those on the auxiliary storage device 2 by matching time stamps, and a loading control part 5 which controls read requests to the auxiliary storage device 2. Then When the operation of the system starts, the program or data are developed in the area of the IC memory 3 and the respective names of the developed files are supplied to the automatic update control part 4 and loading control part 5 to enables the subsequent loading from the IC memory 3 as a substitute for the loading from the auxiliary storage device 2. Consequently, the loading wait time is shortened.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a program and data loading control system, and particularly to a method for loading programs and data on an auxiliary storage device in a computer system equipped with an auxiliary storage device and a main storage device. Regarding control method.

[Conventional technology]

Conventionally, this type of program and data load control method has been a method of directly loading from an auxiliary storage device or indirectly using a disk cache or a RAM disk.

[Problem to be solved by the invention]

The conventional program and data load control method described above is a method in which loading is performed directly from the auxiliary storage device or indirectly using a disk cache or RAM disk, so that the program and data load waiting time is reduced. , there is a waiting time for reloading when the cache misses, depending on how the system is used, the user needs to be aware of the existence of the RAM disk, and every time the system is restarted. The disadvantage is that the same load latency occurs.

[Means to solve the problem]

A program and data control method according to the present invention is a program and data load control method in a computer system including an auxiliary storage device and a main storage device.
non-volatile readable and writable IC memory;
an automatic update control unit that manages and controls the program or data on the IC memory so that it is always the same as that stored in the auxiliary storage device; and an automatic update control unit that controls read requests to the auxiliary storage device and the IC memory. and a load control unit that controls the load from the auxiliary storage device to the main storage device to be replaced by the load from the IC memory when the same program or data as the auxiliary storage device is stored in the auxiliary storage device. .

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, this embodiment includes a main memory device 1, an auxiliary memory device 2, and a nonvolatile IC that can be read and written.
An automatic update control unit 4 that manages and controls the memory 3 and the program or data on the IC memory 3 so that it is always the same as that stored in the auxiliary storage device 2, and controls read requests to the auxiliary storage device 2. And IC memory 3
If the same program or data as the auxiliary storage device 2 is stored in the auxiliary storage device 2, the load control unit 5 controls the loading from the auxiliary storage device 2 to the main storage device 1 to be replaced by the loading from the IC memory 3. It consists of

Next, the operation of this embodiment will be explained.

The operation of a general-purpose computer system having the configuration shown in FIG. 1 when a request is issued to load a certain application program from the auxiliary storage device 2 onto the main storage device 1 will be described.

First, at the start of system operation, the automatic update control unit 4 and load control unit 5 are asked in advance which file name of several programs and data stored in the auxiliary storage device 2 to be transferred onto the IC memory 3. Provide environment setting information for deployment and management.

After making the above preparations, the system is started. At that time, the automatic update control unit 4 performs a status check of the IC memory 3, and the program or data according to the given environment setting information is transferred to the IC memory 3. It is checked whether it exists in the memory 3 and whether it is the same as that stored in the auxiliary storage device 2.

If a program or data that does not exist on the IC memory 3 is found, or if there is a difference in the time stamp, the automatic update control unit 4 copies the necessary program and data from the auxiliary storage device 2 to the IC memory 3, and vice versa. If unnecessary programs and data exist on the IC memory 3,
Delete it. Note that if the necessary programs and data are not present in the auxiliary storage device 2, a display (not shown) will notify the user of this fact.

After the system has started up normally, when the user requests the auxiliary storage device 2 to load a certain application program, the load control unit 5 first refers to the environment setting information and loads the requested application program therein. Check if there is a program with the same name as the program name, and if it exists, change the load source device to IC memory 3. If it does not exist, load it using the conventional method. 3, the automatic update control unit 4 checks whether the program exists on the IC memory 3 and, if so, whether it is stored in the auxiliary storage device 2. After that, a check is performed to see if the program is the same, and if it is normal, the program for which the load request has been issued is loaded from the IC memory 3 to the main storage device. Note that if the specified program does not exist on the IC memory 3, it is once loaded from the auxiliary storage device 2 onto the IC memory 3, then loaded from the IC memory 3 to the main storage device 1, and then If the program does not exist in the system, the system user is informed of this fact by means of a display.

All subsequent load requests to the auxiliary storage device 2 are placed under the control of the load control unit 5 and the automatic update control unit 4, allowing the system user to ignore the existence of the IC memory 3 and No need to change the operating system.

Although the above example of operation relates to loading a program, it is clear that data is loaded in a similar manner.

〔Effect of the invention〕

As explained above, the present invention provides a non-volatile, readable/writable IC memory and a system that ensures that programs and data on the IC memory are always the same as those on the auxiliary storage device by checking time stamps, etc. It has an automatic update control unit that controls the update control unit, and a load control unit that controls read requests to the auxiliary storage device, and expands programs or data to the IC memory area in advance at the start of system operation, and each of the expanded files. By giving the name to the automatic update control unit and the load control unit, subsequent loads from the auxiliary storage device can be executed instead of loads from the IC memory, which has the effect of shortening the load waiting time compared to the conventional method. .
