Abstract

The circuit informs the state of of memory to users when the quantity of line data being inputted exceeds that of memory space, otherwise, storing the data to improve the efficiency of memory managing. The circuit is composed of a keyboard (1), a buffer (2) for temporarily storing the data from the keyboard (1) by one line, and a central processing unit (3) for comparing & discriminating between the data quantity per one line and the space quantity of a memory (4) and a submemory (5) and displaying the sign of overflow when the data quantity exceeds the space quantity, otherwise, storing the data stored in the buffer (1) into the memory (4) and the submemory (5) and executing it.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detection control method for storing data in a memory and a computer system. More particularly, the present invention provides a method of controlling the storage of data in accordance with a detection result by comparing and detecting the amount of space in a memory and the amount of data in a line unit. A detection control method in storage.

In a conventional memory and computer system, data is stored in accordance with a memory key signal input while the program is executed and then terminated. However, when the memory overflows, there is no way for a user to know this. In this state, when the data is stored, the data cannot be stored according to the input of the key signal. From the user's point of view, time is lost and work efficiency is reduced. There was a fault.

In view of such a conventional deficiency, the present invention detects the amount of space in the memory when data is stored, and displays and informs the user when the amount of data for each line exceeds the amount of space in the memory. When the invention is described in detail with reference to the accompanying drawings as follows.

As shown in FIG. 1, a buffer 2 for temporarily storing data in response to a key signal input of the keyboard 1, a memory 4 and an auxiliary memory unit 5 for storing programs and data, and the memory (4) and the display unit (6) and the alarm unit (7) for overflow indication and alarm sound according to the amount of space in the auxiliary memory unit (5), and the central processing unit (3) for controlling the whole system. It is made up.

The operational effects of the present invention configured as described above will be described in detail with reference to the signal flow diagram of FIG. 2.

When the key signal of the keyboard 1 is pressed and the key signal is input to the buffer 2, the buffer 2 temporarily stores the input data in accordance with the key signal by one line and then returns the return key signal of the keyboard 1. When inputted, the central processing unit 3 detects the data amount of one line, and also detects the space of the memory 4 and the auxiliary storage unit 5, and then the data amount of one line is stored in the memory 4. ) And the amount of space in the auxiliary storage unit 5 are compared and discriminated, and when the amount of data in one line is large, the CPU 3 detects that the input data cannot be stored, and displays a memory ( 4) and indicates that the data bank (Bank) of the auxiliary memory unit 5 has overflowed, and controls the alarm unit 7 to sound an alarm, ignoring the data of the last one line stored in the buffer 2 and then pulling it. Ending by setting a flag, while the data amount of one line is reversed from the above, the memory 4 and the auxiliary storage section 5 If the amount is smaller than the amount of space, the data temporarily stored in the buffer 2 is stored in the memory 4 and the auxiliary memory unit 5 through the data line DL, and then initialized until the program execution completion key signal is input. The program returns to its original state, repeats as described above, and terminates when a program execution completion key signal is input.

As described above, when the amount of data input is larger than the amount of space in memory, the user detects and displays the amount of space in memory and the amount of data in the line unit. By doing so, it is possible to improve the work efficiency as well as the convenience which is very convenient from the user's point of view, and to improve the reliability of the management point and the product.

Claims (1)

When the key signal of the keyboard 1 is pressed and the key signal is input to the buffer 2, the buffer 2 temporarily stores the input data according to the key signal by one line and then returns the center to the center when the return key signal is input. The processing device 3 detects the amount of data in one line and compares and discriminates the size by detecting the amount of space in the memory 4 and the auxiliary storage unit 5, and central processing when the amount of data in one line is large. The device 3 indicates on the display unit 6 that the data bank of the memory 4 and the auxiliary storage unit 5 has overflowed, controls the alarm unit 7 to generate an alarm sound, and is stored in the buffer 2. After ignoring the data of the last one line, a full flag is set and terminated. If the data amount of one line is small, the data temporarily stored in the buffer 2 is stored in the memory 4 and the auxiliary device through the data line DL. After storing in the storage unit 5, it repeats until the program execution completion key signal is inputted. Detection control method during data storage, characterized in a.
