Abstract

PURPOSE:To enable high-accuracy debugging operation by providing a memory which is stored previously with data consisting of block-specified address and data parts and a means which outputs transfer data read out of the memory through an arithmetic control means. CONSTITUTION:Through the arithmetic control means 1 such as a CPU mounted on equipment itself, a specific block number is specified for the memory 2 which is stored previously with block-specified data, e.g. data consisting of an address part and a data part. Then, data stored in a memory address specified with a specific block is read out of the memory address by a certain number of bytes through the arithmetic control means 1 and this data is transferred to an output means 3 and outputted. Consequently, real data under the influence of noises, etc., in operation is obtained for a real machine as a completely assembled product and the high-accuracy debugging operation is performed with efficiency.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for outputting debugging data from a memory, and more specifically, the present invention relates to a method for outputting debugging data from a memory. The present invention relates to a method for outputting debugging data from a memory in instruments such as measuring instruments, which are equipped with a means for outputting debugging data and are particularly required to be compact.

[Conventional technology] Shi! Regarding various data such as programs stored in memory installed in various instruments dedicated to measuring instruments, see 5.
By performing debugging work before shipping, i11 is processed to ensure that it is as complete as possible as a product before it can be delivered.

Regarding the debugging work performed in this case, 1.
1j by intervening an emulator which is an external device;
A command is sent in response to the first step, and the data read by this command is sent to the CI on the emulator side.
) The data is loaded into a memory such as a RAM owned by an arithmetic control means such as an LJ, and then the contents of this memory are sequentially checked by an emulator to determine whether the data is good or bad.

[Problems to be Solved by the Invention] By the way, the debugging work described in 1 above, which is performed via an emulator, is excellent in that it allows for smooth tracing as a result.

On the other hand, when it comes to memory that is installed together with arithmetic control means such as a CPU in equipment such as measuring instruments, it is necessary to take into account the effects of noise etc. after it is installed in the housing, so it is necessary to take into account the effects of noise etc. It has also been done to output the data of the memory, which is the contents of the memory, under the condition of depletion, and to examine the contents.

However, it is not possible to connect an emulator that requires an intervening connector to such a finished device, and therefore it is virtually impossible to check the contents of the memory after it is installed. As a result, highly accurate debugging becomes difficult.

This invention was made in view of the above-mentioned problems with the conventional method when outputting data for debugging work. To provide a method for outputting debugging data from a memory, which allows data to be outputted immediately and debugging work to be performed with high efficiency. .

[Means for Solving the Problems] In order to achieve this more specific objective, the present invention is configured as follows. .

That is, the present invention provides transfer data read from 1); and an output means for outputting the
The data stored in the Takabori is inputted via the arithmetic control means (a specific block in the memory is designated according to No. 8, and the content of the data read from this designated block is input to the output means). The feature of the structure is that the control code and result data are outputted to the debug function by making them correspond to each other.

[Example] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram showing an example of the main configuration of equipment such as a measuring instrument used to implement the method of the present invention.

That is, the equipment used for carrying out this invention includes C.
I) Centering on the arithmetic control means 1 such as tJ, in addition to the input terminal T, in addition to the input terminal 2, which is controlled by the arithmetic control means 1 such as 1<AM, etc.

and A/1 which converts the data taken in through the measurement unit 4 into a digital signal] conversion means 6 and arithmetic control means 1
An output signal generator 7 converts output data from the converter into an analog signal and outputs the converted signal, and its output terminal T2. Furthermore, printers and CRTs.

An output means 3 consisting of seven segments LED, etc. is provided. Of these, the arithmetic control means 1
A second device is capable of reading data by specifying an address from the main device 2, which is made of M, etc., and sequentially transfers the data to the output device 3, which is a printer or the like, and outputs the data. The figure is a flowchart showing the processing procedure when the method of the present invention is applied to a device having such a configuration.

In other words, arithmetic control means such as a CPU installed in the device itself! First, a process is performed to designate a specific block number for the block 2 in which predetermined data designated as a block in advance, for example, data consisting of an address part and a data part, is stored. In this case, the specific method for specifying the block number is to input a numerical value according to a predetermined program by key input, etc., and specify the address.

After passing through such processing steps, from the memory address specified by the specified block, the arithmetic control means 5 calculates a certain number of bytes of data stored in the memory address.
6, the data is read out via the output means 3 and outputted by transferring it to the output means 3.The specific output data obtained in this case is as follows.

For example, in addition to the address of a designated block, the data held at that address, for example, data consisting of a control code and result data! It is preferable to output a hexadecimal number and an ASCII notation corresponding thereto by printing a predetermined number of bytes using a printer.

The method of this invention is capable of outputting debugging data from the memory, for example, data consisting of a control code and result data, through such processing steps.
Therefore, by verifying the data consisting of the control code and result data, for example, if rNGJ, which means an error, is output from the output means 3, it is possible to find a clue as to why. Or, if data is output that shows the circuit is open when it is actually closed, this can be used as a clue to find out the cause of the error information displayed in the output data. It is relatively easy to find out which program is being used based on the relationship with the program that is set to F.

In addition, since such debugging data can be output without going through an external device such as an emulator, the actual machine as a finished product can be easily affected by noise during operation. It can be obtained as the actual data below, and furthermore, it can be easily outputted as data for analysis by the user where the equipment is actually installed, allowing for quick response. .

E Effects of the Invention] As stated above, according to the method of this invention, c p u
Even in the state of an actual machine, which is a finished product by incorporating a device equipped with a memory controlled by a calculation control means such as Since the contents can be immediately output as data, debugging data can be obtained under actual operating conditions exposed to the influence of noise M, such as at the actual installation site of the device, allowing for highly accurate debugging. Able to perform work efficiently.
