Abstract

PURPOSE:To display how long a waiting state is continued, by constituting the titled system so that a timer is started and an interruption is generated at every prescribed time, when a computer system enters into a waiting state, and deriving the remaining waiting time with the interruption as a turning point and displaying it. CONSTITUTION:By a program 2, operator's action waiting is instructed by a prescribed time T and set to a timer 6, and the time T is displayed on a CRT 9, as well. Subsequently, when the timer 6 is started, its contents are subtracted in accordance with a clock signal, and whenever one second elapses, an interrupting signal (b) is outputted. When the signal (b) is outputted, the contents of a register 7 are subtracted by '1', and the remaining waiting time is indicated. The contents of the register 7 are edited and added to a CRT control part 8, and the remaining waiting time is displayed on the CRT 9. An instruction executing part 3 checks the contents of the register 7, and unless the contents are '0', the interrupting signal (b) returns to the waiting state, and in case of '0', it is decided that the waiting time T has elapsed, and an operation of the timer 6 is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a computer system, and more particularly, when a computer system enters a waiting state in which an operator waits for the next action, the waiting time can be displayed. Regarding the possible waiting state display method.

[Conventional technology]

Conventionally, when a computer system enters a waiting state in which an operator waits for a predetermined amount of time for the next action, a display device displays a fixed pattern or a particular lamp flashes.

[Problem that the invention seeks to solve]

However, in the conventional method described above, although it is known that the computer system is in a waiting state, it is not known how long the waiting state will last.

Therefore, for example, when testing a computer system using several types of test programs in which the computer system enters a wait state when each test program is executed,
The operator must constantly monitor the above-mentioned display device or lamp while the test program is being carried out, and when the test program is completed, the operator must run the next test program and cannot perform other tasks. Therefore, there was a problem in that the work could not be carried out efficiently and in a planned manner.

The present invention solves the above-mentioned problems, and its purpose is to make it possible to display, when a computer system enters a wait state, how long the wait state lasts.

Means for Solving Problems c] In order to solve the above-mentioned problems, the present invention provides a computer system with a timer whose contents are decreased as time passes and which generates an interrupt every time a predetermined period of time elapses. and when the computer system enters a waiting state in which it waits for the next action by an operator for a predetermined time, the timer is activated after setting the wait time in the timer, and an interrupt is generated every time the predetermined time elapses. The remaining waiting time is determined using this as an opportunity, and the remaining waiting time is displayed on the display device.

[Operation] The timer is activated when the computer system enters a wait state, and generates an interrupt at predetermined intervals.

Then, the remaining waiting time is determined in response to an interrupt from the timer and displayed on the display device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a pronk diagram of an embodiment of the present invention, which includes a memory 1 in which a program 2 is stored, an instruction execution section 3, a clock generator 4 that outputs a clock signal of a predetermined frequency, and an instruction execution section 3. When the gate circuit 5 opens and closes according to the signal a output from the gate circuit 5 and enters a waiting state in which it waits for the next action by the operator, the waiting time T (in seconds in this embodiment) is set as an initial value by a program instruction. the content is reduced according to the clock signal set and applied from the clock generator 4 via the gate circuit 5;
A timer 6 that outputs an interrupt signal every time a predetermined time (one second in this embodiment) elapses, a register 7, and a CRT.
It is composed of a control section 8 and a CRT 9.

FIG. 2 is a flowchart showing part of the processing contents of the instruction execution unit 3. When the program 2 instructs the operator to wait for the next action for a predetermined time T, the command execution section 3 sets the waiting time T in the timer 6 in step 10.

In step 20, this waiting time T is stored in the register 7. Proceeding to step 30, the contents of the register 7 are edited and output to the cRT[m circuit 8. As a result, CRT9
As shown in FIG. 3 (al), T is displayed to inform the outside that the program 2 has entered a waiting state for T seconds.Next, in step 40, timer 6 is started. This is done by opening the gate circuit 5 by a and supplying the clock signal from the clock generator 4 to the timer 6.

When the supply of the clock signal is started, the timer 6 subtracts its contents in accordance with the clock signal, and every second, that is, its contents are subtracted as shown in FIG. 3 (bl, tc+).

..., rT-IJ, rT-2J, as shown in (n),
....

An interrupt signal is output every time rOJ is reached.

When the interrupt signal is output from timer 6, step 6
Control is transferred to 0. In step 60, the contents stored in register 7 are decremented by 1. That is, the contents of register 7 will indicate the remaining waiting time. In step 70, the contents of the register 7 are edited and added to the CRT control section 8.
Display the remaining waiting time (remaining waiting time) on RT9. In step 80, it is checked whether the contents of register 7 are "0".

At this time, if the contents of register 7 are not rOJ, it is necessary to continue waiting, so the process returns to step 50 and is set to "0".
”, it means that the waiting time T has elapsed, so the operation of the timer 6 is stopped in step 90.

Therefore, every second after starting timer 6,
That is, the contents of timer 6 are as shown in FIG. 3 (fbl, fc).

..., rT-IJ, rT-2J, as shown in (n),
....

An interrupt signal is generated every time it becomes "0", and step 60
．． Since the process 70 is performed, the display contents on the CRT 9 become as shown in (b) and (C1,..., (n)) in the same figure.

Although not explained in the above embodiment, it is also possible to use an interval timer as the timer 6. However, in this case, it is necessary to provide the interval timer with a function of generating an interrupt every time a predetermined time elapses.

〔Effect of the invention〕

As explained above, the present invention allows the remaining waiting time to be
Since the information is displayed on a display device such as 9, the operator can work efficiently and systematically.
