Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic computer having a program execution time measuring means.

[Prior art]

Do electronic computers (hereinafter referred to as computers) used in control devices such as servo systems use sample values? It is controlled to execute relatively short-cycle refreshing time processing based on the li'II control theory, and performs coordinate transformation, filter calculation, extrapolation calculation, and %HI control of the signal converter and one-person output control.

All other processing of each food item is required to be performed within the specified time rdl.

Therefore, it is important to understand the program execution time, and a means to measure this is required.

One of the conventional methods to meet such demands.

There is a method of reading a timer used to obtain the time standard of the processing cycle before the start and after the execution of 10 grams to be measured, and calculating the time difference to obtain the execution time. This is simply done by appropriately distributing instructions before and after the instruction to read the timer and the instruction to calculate the total time difference, etc., and outputs a total of 111j results. There is also a programmatic method.

[Problem that the invention seeks to solve]

Conventional total of 1! The L machine is better! ! To measure the execution time using a method like this, if you want to measure the execution time of any program or part of a program, use #'
It was very inconvenient as the XIJlj program was very expensive.

This invention was made to eliminate these drawbacks, and is a computer that can measure the execution time of any program with simple operations. The purpose is to obtain.

[Means for solving problem f]

The tt calculator according to the present invention includes: address setting holding means for setting and holding arbitrary two addresses; measured program detecting means for detecting whether the program under test is being executed; It is equipped with a counter for counting.

[Effect]

In this invention, by setting a start address and an end address of a program to be measured, a color controller is operated while the program to be measured is being executed to measure the execution time.

〔Example〕

@1 Is Figure 1 an example of a computer program execution time measuring means according to the present invention? FIG. In FIG. 1, ill is an address setting saver i for setting and holding the start address and end address of the program under test.
means, +21ij program counter; f31ti program-under-test detection means for detecting whether the program under test is being executed; (4) is a reference clock generator; +51
V'i counter (61Fi display means).

FIG. 2 is a detailed view of the embodiment shown in FIG. In FIG. 2, address setting holding means 111, Fi maintenance panel αυ, address setting circuit 03. The address register 1 (13) and the address register 20J consist of the program under test detection means (31 is the comparison circuit ICII), the comparison circuit 2 (to) and the free lag flop field.The display means 16) includes the display control circuit M and the maintenance panel a
At υ! ! RIR.

Next, the operating pressure will be explained with reference to FIG. By adding Ω to the start address and end address of the program under test by operating a switch on the maintenance panel aLl, these are held in the address register i3 and the address register 2I, respectively. Now put the computer into running state.

Program color/re (the contents of 21 are address register 1)
When the contents of 03 match, the comparison circuit ill outputs a signal, thereby clearing the counter (5) and setting 7 lip 70 tsugro. As a result, the counter (5) is set to 1. - Pull and starts counting all the clocks output by the reference clock valve (41). Then, when the contents of the program counter (21) match the contents of the address register Q4, the comparator circuit 2ω outputs a signal, which causes the free lag flop G3 to output a signal. Reset the counter, +5125; Stop the count, and the count value will be transferred to the display IIN'! 1 and displayed on the maintenance panel αD. [7 Therefore, by visually observing this, the program can be executed. I can tell the time.

C Effects of the Invention] As explained above, this invention can easily and quickly reduce the execution time of any program or its minutes or the load time of one entire processing cycle by setting the start address and end address. It has the effect of being measurable.

[Brief explanation of drawings]

FIG. 1 is an overall configuration diagram showing an embodiment of a computer program execution time measuring means by this issuing EA, and FIG. 2 is a detailed diagram of FIG. 1.
i program counter, (3) is a program under test detection means, (4) is a reference clock generator, (5) is a counter, and 161i"! display means. In the figure, the same reference numerals Fi are the same or equivalent parts. .

Claims (1)

[Claims] An address setting holding means for setting and holding two arbitrary addresses, a program counter holding the execution address of the program, and the contents held by this program counter and the address setting holding means when the program under test is being executed. a reference clock generator; a counter that counts clocks from the reference clock generator under the control of the program-under-test detection means; and a counter that displays the count value of the counter. 1. A computer comprising display means, and configured to measure the execution time of the program by setting a start address and an end address of the program to be measured in the address setting holding means.
