Abstract

PURPOSE:To reduce the power consumption by constituting the equipment so that an operation of an input/output buffer can be controlled only when an option board is installed. CONSTITUTION:Whether an option board is installed on an option slot 105 or not is detected by using an automatic detector 107, and only when it is installed, an operation of an input/output buffer 104 can be executed from a control circuit 106. Also, in the software, by adding a software control circuit 108 by which the operation of the input/output buffer can be executed only at the time when the option slot is installed, after the system rises, it is realized to further reduce the power consumption.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] This invention relates to a computer device with a built-in battery, consisting of a CPU and peripheral circuits, having an option slot, and into which an option board can be installed.

[Prior Art] Generally, the configuration of a computer device consisting of a CPU and peripheral circuits, having an option slot, and into which an option board can be installed is shown in FIG. Drive capability with option board, bidirectional control, and protection of internal circuits are required. Therefore, after the power is turned on, addresses, data, control signals, etc. are connected to the five-object slot through the external input/output cover sofa.

[Problem to be solved by the invention] However, 1i! Reducing power consumption when using batteries is an important issue for combination coater devices with built-in reservoirs. Particularly, in a computer device with a built-in battery that supports option slots, increased power consumption in the operation of an input/output buffer for the option slots is a problem. Furthermore, as computer devices become faster, power consumption increases significantly.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and its purpose is to provide a computer device with a built-in battery that consumes less power and has a long lifespan and can be equipped with an external option board. Means for Solving the Problems 1 The battery built-in computer device of the present invention consists of a U and a peripheral circuit, has an option slot, and can be fitted with an option board, and when the option board is inserted, The feature is that it is possible to automatically control the operation of the input/output buffer of the computer device.Furthermore, after inserting the option board, the operation of the input/output buffer and the power on of the option board can be controlled. The present invention is characterized in that it is provided with a control signal that enables it to be turned off, and is provided with a display means that indicates whether or not an output buffer is installed and the operating status of the option board.

[Example 1] Hereinafter, the present invention will be described in detail based on Examples.

FIG. 1 shows a configuration example of a battery built-in computer device of the present invention, which is composed of a CPU and peripheral circuits, has an option slot, and can be fitted with an option board. Lot is CPtJ (central processing unit), 102 is , internal memory, 10311 peripheral circuits, clock generator, bus controller, 111 included controller, DM
The basic system consists of A controller, timer, etc.

Furthermore, by providing an option slot 105 through the input/output buffer 104, it is possible to connect an option board, making it possible to construct an expandable system. However, in the case of a computer system with a built-in battery, it is important to save power consumption, and the function of stopping the operation of the input/output buffer 104 shown in the present invention is
Power consumption can be reduced. As a method of implementation, an automatic detector 107 that automatically detects whether an option board is installed on the option slot 105 is used to automatically enable the operation of the input/output buffer from the control circuit 109. Further, in software, by adding a software control circuit 108 that enables the input/output buffer to operate only when an option slot is installed after system startup, further reduction in power consumption can be achieved.

Furthermore, by providing a function to stop the operation of the input/output buffer and turn off the II power source when an option slot is installed, lower power consumption can be achieved.

FIG. 2 shows an example of the above flowchart. In other words, after the power is turned on (201), it is automatically checked whether the option board is installed in the option slot (202), and if it is not installed, the operation of the traffic buffer is started. The option board is stopped (203), and when installed, it is checked whether the option board is used (204), and the input/output buffer and the input/output buffer are checked.

The software selects whether the slot power is turned on (205) or turned off (206).

Based on the flowchart described above in FIG.

From the signal 301 from the computer device to the slot (
302), an option slot automatic detection signal 303 showing an example of a signal controlled through the input/output buffer 305.
．． And, using the software input/output control signal 304,
It is input to the control terminal of the input/output buffer 3.5 and controls the operation of the input/output buffer. As a result, when the option board on the slot is not used, the operation of the input/output buffer 305 is stopped, and power consumption can be reduced. moreover,
By also turning off the power switch 308, labor can be saved.

The automatic detection of whether or not the option board is installed can be achieved by using a mechanical switch when the option board is installed, or by using a photo incretor. Also,
This is achieved by allocating one of the slots to the automatic detection signal 9.

In addition, a display device 306 is used to indicate whether or not an option board is installed and the operating status, thereby making it possible to reduce labor and reduce errors.

[Effects of the Invention 1] As described above, the present invention provides a computer device with a built-in battery that is composed of a CPU and peripheral circuits, has an option slot, and is capable of installing an option board, when the option board is inserted. By making it possible to automatically control the operation of the input/output buffer of the computer device with a built-in battery, it is possible to automatically stop the operation of the input/output buffer when the option board is not installed, reducing power consumption. This has the effect of making it possible to save labor and extend the life of the power source when it is in use. In particular, automatic recognition (5) has the effect of increasing the lifespan without errors.

Furthermore, by providing a control signal that enables the operation of the input/output buffer and the power on/off of the option board using software only when the option board is installed, the This has the great effect of reducing power consumption.

In addition, in computer equipment with a built-in battery, we have provided a display that can identify the presence or absence of an external option board, the operation of the input/output buffer, and whether the power is on or off. , it also has the effect of reducing power consumption when the option board is not in use6.
