Abstract

PURPOSE:To make the extension and alteration of a system easy, by storing a driver routine driving an input/output module itself in the said module. CONSTITUTION:Input/output modules A11-A1N for the input/output interface and control are mounted with a memory M3 storing a driver routine driving the said modules. The memory M3 is incorporated with the modules A11-A1N as the hardware and the software of the said moudles and packaged. A main memory module M11 and an auxiliary memory module M12 have no driver routine for the modules A11-A1N and only have the software processing the connection of programs stored in the memory M3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in memory monoyl systems applied to electronic computers, microcomputers, and other applied products.

Generally, in this type of memory monole/stem, as shown in FIG.
Main memory module M, auxiliary memory module M
In addition to 2, input/output monomers A1 to AN such as interfaces and controllers are connected to form an fc configuration. Therefore, in such a conventional system, the main memory module IVIJU not only stores the driver routines that drive each module A1 to AN, but also stores data such as the product operation routines, etc. that operate the M machine. Furthermore, the main memory module M1 has monolayers A1 to AN as hardware and 1 to the same monolayer.
- Driver routines as software of AN have a pairwise relationship with each other and are stored with mutual compatibility.

Therefore, the conventional system has the following drawbacks. That is, each mono module A is connected to the main memory module M.
Since the configuration stores the driver routines 1 to AN, when creating the system, it is necessary to design and develop the argitichnaya in advance. In addition, after completing the Kai Seven Noyule System, each Seven Nole Ml, M
2. When redesigning the hardware of A1 to AN, it is necessary to maintain the previous architecture and further adapt it to the driver routine. If this architecture is not followed, the main memory of the monoyl system Mononyl I
vll1 or the auxiliary memory module M2 must also be changed.

Furthermore, in a general seven-node system, instead of creating all seven nodes at once, the core parts such as the main memory module M1 and the auxiliary memory module M2 are created first, and then the various input and output mononoles A1 are created. ~The aim is to complete the AN and enhance the system. In this case, the operating system uses the following driver routine storage method. ■A method of storing only the driver routines used in the system, ■A method of storing only the driver routines used in the system, (2) A method of storing only the driver routines used in the system, ()) A method of storing only the driver routines used in the system, (2) a method of storing only the driver routines used in the system; Including dry...
This is a method in which the data is stored in kilometres. However, the current storage method for Teha, ■, and ■ is main memory monoyl M7.
Since the memory size of N (11i) is wasted in the memory size of M2, method (i) is usually used. In particular, in the ■method, it is difficult to realize archaichnaya based on reliable foresight. Therefore,
As long as the routine storage method of ■ and ■ is adopted, there is a sense of security in adding or changing the 1st driver runn of each monole according to the situation at that time, but as shown in Figure 1, the drivers of each module A1 to AN Storing routines in the main memory module M could not easily meet this requirement.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to store a 1/2 clipper routine for driving the same monol in the turnout module itself, thereby making it easy to expand and change the system. The present invention provides a memory module system that can be used for various purposes.

Hereinafter, one embodiment of the present invention will be described with reference to FIG. In the same figure, C is a CPU with Nakao function 1A- function.
Mll is a main memory monoyl that stores processing calculation data, and M12 is an auxiliary memory monoyl that stores processing calculation data that is not used all the time but is used only when necessary. AIl~AJN are input/output modules for input/output interfaces and controls for controlling peripheral devices such as typewriters, printers, etc., and these monolayers AIl~AJN have the same monolayers All~A7.
A memory IJ M 3 is implemented that stores the driver routines that live N19. Therefore, this memory M
3.11 to monoyl as no-ware
N and the software of the same monols All to AJN are integrated and packaged. This means that when performing a grade door, the input/output modules AI1 to AI
The main memory module M1, auxiliary memory module M2, etc. do not need to have their own driver routines for each monolayer All to A1N, and in relation to the memory M3, the same memory 5 - All you need is the software that handles the connections between the programs stored in the M3. Moreover, this software is not regular software that is directly connected to the hardware stored in the memo I) M3, but may be rough software with flexibility. Note that the memory M3 is a ROM (R
ead OnlyMemory), etc.
Random Aaces
a Memory) may also be used. ROM
・Semiconductor memories such as RAM and RAM have become large-capacity and low-priced in recent years, and providing a portion of the main memory between A and L'2 to each module AIl to klN means that the address space of the computer becomes extremely large. This is not a problem as it is a trend.

17. When data processing is executed in the above-mentioned apparatus, the CPU monochrome C requests data necessary for the processing from the main memory module M1. Data ij read out by memory monologue M: After being stored in the instruction register of CPU module C, processing is executed according to the program. At this time, it becomes necessary to operate peripheral devices, etc. f?
:, the CPU monoyl C transfers the program to the input/output modules A11-klNII (glossy) and temporarily disconnects the main memory monoyl Mlk. Therefore, after jumping, each input/output module A11-A2N becomes the driver of the memory M3. It drives peripheral devices, etc. according to the routine. After the drive is finished, the CPU module C returns to the operating system of the main memory module M1 and executes the program by inputting the end signal. In this way, the main memory module M1 only needs to handle important system processing.

Note that the present invention is not limited to the above embodiments.

For example, memory M in each person's output monochrome A11 to AJN
In addition to the driver routines of the modules ALL to AIN, if there is an unused space, individual programs may be stored in this space. For example, the diagnostic routines of Mononeal A11 to AJN may be stored therein. This diagnostic routine for testing monoyl AJJ~AJN's own materials is useful for glazing the appropriate sound main memory monoyl M1 or auxiliary memory monoyl M2, but depending on the user's needs. It is not necessary to keep it for 1 hour at all times.

In particular, in the conventional system, when a trouble occurs, the input/output monocles AJJ to A7N are often diagnosed by storing the information in the soi/memory monocle M1 using an input device or the like. In this regard, in this system, the diagnostic routine is empty in the memo M3 of the modules AIl to AjN, and the space VCV6K is
If the CPU module C is used by calling a diagnostic routine when an abnormality occurs, hardware troubles can be discovered and dealt with in a short time. In addition, 4iIlz can be modified and implemented without departing from the original idea.

As described above, according to the present invention, the dry 1-routine that drives each output module is built into the memory of the monorail itself, which greatly reduces the time it takes to develop the architecture of the entire system. It can be shortened to

Since each input/output module integrates the hardware and software by itself, it is possible to freely commercialize the hardware later without being constrained by the rules of an already completed architecture. In addition, the system as a whole is highly flexible; even if routines are added or changed later, the input/output module itself can be replaced; this means that the system can be expanded or changed even while the system is in operation. ff:'6 It is possible to provide a memory monoyl system that can be easily realized.
