Abstract

PURPOSE:To prevent an erroneous calculation and to improve work efficiency by providing plural memory parts where size data on a program module is stored and a means for calculating an address at which the program module is stored. CONSTITUTION:The modules P1-Pn of a system program are stored on a file 1, and are loaded in the program area 3 of a main memory part 2 at initial loading. In a memory 8 a processing program 9 (utility) is stored, and is activated when an operator inputs an activation command ST through a system console 6. With the execution of the program 9, a processor 5 takes member names M1, M2 and Mn out of a control table 7, whereby segment sizes S1-Sn of the modules P1-Pn are taken out of an interface part 10. On the basis of the size data the address at which the modules P1-Pn are stored is calculated. Thus the address calculation can be done without man power, and accordingly a calculation error can be prevented and the work efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides an initial load (IPL) in a processing system.
), the present invention relates to an automatic memory sourcing method that automatically allocates a memory address at which a module extracted from a file is loaded into main memory.

In processing systems, it is desired to automate the memory mapping work that is essential when generating system programs.

[Conventional technology]

Recently, control devices with built-in processing devices, such as terminals, have become popular. In such a terminal, a group of program modules executed by a built-in processing device are stored in an external storage device, for example, a floppy disk. Therefore, by performing IPL before using the terminal, the 70 cards are executed by the processing device (and the terminal is controlled (processed)).

In order to load a group of program modules into the main memory (CI) during the above IPL, it is necessary to determine in advance the respective addresses at which each program module is loaded into the main memory. It is called.

Conventionally, this memory mapping has been done manually. That is, the system administrator must manage each program component (
Confirm its size from the materials related to Mojerun,
The address to be loaded into the main memory was calculated and the mapping address was manually set in the processing system.

[Problem that the invention seeks to solve]

In the conventional method, address determination is done manually, on a desk, and calculation errors are likely to occur.Especially in the case of terminals, one system program must be created for each user, which does not improve work efficiency. There was a problem.

[Failure to solve the problem]

The above problem is that the program module has a file in which the program module is stored, a processing section, a main memory section, and an input section, and the program module in the file is stored in the main memory section according to instructions from the input section. In a processing system for loading the program module into i, the size data of the program module is stored.
! means for storing the program module name and address data in the storage section of WL2, the storage section of WL2, and the storage section of WL2; when the program module name is input from the input section, the address is calculated based on the size data Vc corresponding to the program module name, and the obtained address is Address data is stored in the second storage section, and when the command is input from the input section, the program module in the file is stored in the main storage section based on the information in the second storage section. (This is solved by the automatic memory mapping method of the present invention that causes loading.

[Effect]

As described above, the present invention eliminates the need for manual mapping processing. This makes it possible to prevent human errors and improve work efficiency as well.

[lol example]

Hereinafter, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram for explaining one embodiment of the present invention, and FIG. 2 is a flowchart for explaining one embodiment of the present invention.

In the gl11 diagram, the file IK stores the system program modules P, ~Pn, and at the time of initial loading (IPL), the required modules are transferred to the queen data memory section 2.
Load it into program area 3 of . In addition, modules P1 to Pn are member names C1 of management s4 of file l.
j & another code) Managed by M+ -M n.

In addition, the segment size s1 to Sn of each module is stored in the interface section IO.

In this manner, the terminal device incorporating the processing device 1115 generates a system program for each user.

At this time, the operator selects the name of the module to be loaded, such as module name P*, Pn, and member of Pn.
Mt and Mn are input from the system console 6. This input member salt (Mt9Mt and M
n) is controlled by the processing bag flt15 in the control table 7.

Next, the operator issues a startup command S from the system console 6.
Input T to start the processing program (neuterity) 9 in the memory 8. FIG. 2 is a flowchart showing an outline of the processing of the processing program 9, and the following control operations will be explained according to the procedures of this flowchart.

〔Effect of the invention〕

Since the present invention does not rely solely on manual calculation of the address of the main memory section into which the module is to be loaded, it has the advantage of preventing calculation errors and improving work efficiency.
