Abstract

PURPOSE:To process the input data inputted from the keyboard at a high speed without data loss. CONSTITUTION:The keyboard is composed of a FIFO buffer 21 monitoring and storing the interruption from the keyboard, a batch takeout part 31 taking out the interruption from the stored keyboard in a batch, an analysis/ optimization part 32 analyzing and optimizing the content of the taken-out interruption, and a processing part 33 executing the processing corresponding to the optimized interruption. The interruption data stored in the FIFO buffer 21 is taken out in a batch, and the content is analyzed to perform the optimum execution. Thus the load to an electronic computer system is reduced and the processing is improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard input control system, and more particularly to a keyboard input control system in an electronic computer system.

[0002]

2. Description of the Related Art In a conventional electronic computer system, in order to prevent data loss of keyboard input data input at high speed, when an interrupt from the keyboard input device is detected, a buffer storage device provided in the electronic computer system is used. The data once input is accumulated. The keyboard input data accumulated in the buffer storage device is sequentially taken out asynchronously with the keyboard input device and processed for each keyboard input data.

[0003]

In the conventional method described above, when the user inputs a keyboard at high speed when the load of the electronic computer system is high and the processing capacity is low, the keyboard input to the buffer storage device is performed. There is a drawback that keyboard input data is difficult to retrieve from the buffer storage device while data is stored. For example, in the case of a processing device in which the screen display scrolls while pressing a certain arrow key on the keyboard and stops scrolling when you release your finger from the arrow key on the keyboard, the load on the computer system is high. If you continue to press the arrow keys on the keyboard while the processing capacity is decreasing, the keyboard input data will only be stored in the buffer storage device and the screen will not scroll, or if you release the arrow keys, the buffer storage device Since the keyboard input data is accumulated in the screen, the scroll display of the screen does not stop immediately, which results in confusion for the user.

[0004]

According to the keyboard input control method of the present invention, in an electronic computer system, a buffer means for monitoring and accumulating interrupts from the keyboard input device, and an interrupt from the accumulated keyboard input device are collectively processed. It is provided with a batch extracting means for extracting, an analyzing / optimizing means for analyzing and optimizing the content of the extracted interrupt, and a processing means for executing a process corresponding to the optimized interrupt.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention in which a keyboard input control system is applied by software.

The data input from the keyboard input device 1 by the user is stored in the FIFO by the interrupt monitoring task 2.
It is stored in the buffer 21. The processing task 3 is a task that operates asynchronously with the interrupt monitoring task 2. The processing task 3 refers to the FIFO buffer 21 in the interrupt monitoring task 2 to take out the stored keyboard input data, and executes the corresponding processing. The processing task 3 has three layers of a batch extraction unit 31, an analysis / optimization unit 32, and a processing unit 33. In the batch extraction unit 31, the FI in the interrupt monitoring task 2 is
Referring to the FO buffer 21, when there is no keyboard input data in the FIFO buffer 21, the processing task 3 is put into a sleep state, an interrupt is generated from the keyboard input device 1, and the keyboard input data is stored in the FIFO buffer 21 of the interrupt monitoring task 2. Waiting to be accumulated. Already FI
When the keyboard input data is stored in the FO buffer 21, the entire contents of the FIFO buffer 21 are taken out at once and the control is passed to the analysis / optimization unit 32 in the next layer. The analysis / optimization unit 32 analyzes the keyboard input data string by, for example, rearranging the order of the data string according to the processing content, and generates the most efficient processing request of the keyboard input data. The processing request is executed.

For example, in the case of a processing apparatus in which the screen display scrolls while the arrow keys on the keyboard are pressed and the scroll display on the screen stops when the finger is released from the arrow keys on the keyboard, the conventional method is shown in FIG. As shown in, the keyboard input data is fetched from the FIFO buffer 21 by the sequential fetching unit 34 at each interruption, and the corresponding processing is sequentially performed. If the interrupt by the arrow key is made eight times, the scroll display request is executed eight times correspondingly. In the case of the keyboard input control method of the present invention, the analysis / optimization unit 32 calculates the final scroll display position by analyzing the number and direction of consecutive arrow keys and directly generates the request for displaying the calculated position. In order to
The number of scroll display requests to the processing unit 33 is greatly reduced.

[0009]

As described above, according to the present invention, the interrupt data from the keyboard input device accumulated in the buffer storage device is collectively fetched, the interrupt contents are analyzed, and the optimum processing is executed, thereby the electronic computer. This has the effect of reducing the load on the system and improving the processing capacity.
