Abstract

PURPOSE:To decrease the amount of fed data to an irreducible minimum and reduce an I/O occupying time by a method wherein a displaying device is composed of a memory access selector for a refresh controller and of a memory address decoder for specifying a specified address in a refresh memory. CONSTITUTION:As a fed data of a computer 1 is sent by an I/O control device 5 to a display data control device 6, the result of decision by a memory access selector 8 within a display control part 7 is expressed by an EF code, resulting in that a signal of refreshing only a part enclosed by EF-LOAD and EF-TERM is sent to a refresh controller 11. If it is a refresh memory address word, an address value within the refresh memory address word is analyzed by a memory address decoder 9 and then the address of this value is set at the head and the subsequent data is loaded to an address in a refresh memory 10. The data stored in the memory 10 is periodically refreshed by the refresh controller 11 and displayed in the CRT monitor 13 by a symbol generator 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application 'EF'1 This invention relates to a tactical large and small device for controlling the man-machine interface in the combat command system of a destroyer.

[Prior Art 1 No. 6''1IIJ is a diagram showing a conventional display device (display 17).

In Figure 6, the console-operated sorter operates a console panel (3) on which various buttons, switches, etc. are arranged, and the results of the operation are sent as function codes via the panel control device (4) and the input/output side control device (5). Calculator (
1).

The computer (1) decodes the operator's command using this function code and sends the response to the display console as transmission data.

The data sent by the computer (1) is first sent to the input/output side control device (5), and then sent as output data to the display data control device (6), which judges whether the data should be displayed on this console or not. Only the data to be displayed is sent to the display control section (7).

The data sent to the display control section (7) is stored in the rear I mesh memory (10) and periodically refreshed by the refresh controller (11).

The refreshed data is converted into tactical figures such as lines, circles, ellipses, route symbols, etc. by the symbol generator (12) and displayed on the CR'T' monitor (13).

Figure 2 shows the refresh memory (]0
) is an EF (external function) codeword format for loading into a file.

The I-F code is set by the EF-, -I, OA D command and the EFTI-F code according to the instructions of the pins 1, 8, ]-7.
Length M command 1 k is distinguished, and furthermore EF-L(tsuA]j
The command can be divided into two types: an I-tub town method in which data is written from the top of the freshco memory, and a volume-up method in which data is written from the bottom.

The part sandwiched between the E F-L OA, D command and the EF-TET≧M command is processed by the fresh controller (11), and the CRTJ is
The second symbol is displayed.

Note that refresh memory (]O) is a specific memoria]
You can specify <1 no., always at the top of memory.
Since the interface is designed to write from the lowest position or the lowest position, if one new symbol is sent as an output button, all the previously displayed figures will be erased from the CRT monitor (13).

In other words, the program processing within the computer ( ) is such that new data must be added to the previous data before being sent out.

[Problem to be solved by the invention] However, in the conventional tactical display device, all data is stored as EF-LOA I) and EF-TERM.
Because the refresh memory was loaded between commands using a top-down or home-up writing method, the amount of computer data sent at one time was enormous, and the time occupied by I10 due to data transfer was reaching the system's limit. , there were the following problems.

Periodic tasks within the computer may be skipped due to increased occupied time, causing system malfunctions.

In addition, the C I-'U load, which correlates with the hardware-related increase in ■／○ operation time, has increased, and the delay in response time to operator actions has become large, making it necessary to build a system that is even more complex than the current one (new connections with external devices). etc.) cannot be performed.

This invention was made with the aim of solving this problem, and by specifying a specific address in the refresh memory and writing only, the amount of computer data sent at one time can be minimized, and the I10 It reduces time, facilitates the construction of even larger systems in the future, and
- The vast amount of software resources in the past that displayed tactical information in either a bottom-down or bottom-up writing format.
The purpose is to be able to use the system without changing it at all.

[Means for Solving the Problems] The tactical display device according to the present invention has two display control units that identify whether it is an EF code or a refresh memory address word,
A memory access selector that instructs the refresh controller whether to refresh the entire refresh memory or refresh only the portion surrounded by the EF code.

The memory address decoder analyzes the address values of the refresh memory l<1 nowar1 and specifies a specific address in the refresh memory.

[Operation] In this invention, the memory access selector determines whether data sent from the data control device is an EF (external function) code or a refresh memory address word, and the memory address decoder uses the memory access selector to refresh the data. Analyze the address value of the word that is determined to be a memory address.

Determine at which address in the refresh memory the following data should be stored.

The refresh memory is specified by a two-legged memory address decoder, and actually holds the data sent out from the computer, and the refresh controller periodically refreshes the data in the refresh memory and sends it from the computer. Continuously displays data even if no data is sent.

[Embodiment] FIG. 1 is a functional diagram of a bar 1 (wear) in a tactical display device of the present invention.

The console operator operates the console panel (3) and the result of the operation is read into the computer (1) as a 32-bit function code via the panel control device (4) and the input/output side control device (5).

This function code is analyzed in the machine (1) to recognize what action the operator took.

The computer's response to operator actions is tactical information consisting of route symbols, lines, circles, ovals, etc.
This is a monitor display.

The computer (1) sends data to the display console for information display, but this computer sent data is first sent to the input/output side control device (5) and from there as output data to the display data control device (6). sent to.

The contour address in the EF code shown in Figure 2 or in the refresh memory address word shown in Figure 3 determines whether the data in question is data to be displayed on this console, i.e. the refresh memory this console has. It is determined whether the data is stored in the .

If it is determined that the data is display data, the memory access selector (8) in the display control unit (7) will load the data into the refresh memory using the I/bottom-down write method or bottom-up write method using the EF code. , a refresh memory address word determines whether data is to be loaded into a particular location in the refresh memory.

For EF code: E F-L OA, D and EF-T
A signal indicating that only the portion surrounded by the ERM is to be refreshed is sent to the refresh lnosh controller, and if there is no such signal, all data in the refresh memory is to be refreshed.

For refresh memory address words.

The memory address decoder (9) analyzes the address value in the refresh memory 1 to 1, and the subsequent data is loaded into a predetermined address in the fresh memory (10), starting from the address indicated by this value.

The data stored in the refresh memory is periodically refreshed by a refresh controller (11), and a symbol generator (2) displays route symbols, lines, circles, and ellipses on the CRT monitor (13). is displayed.

FIG. 2 is a word format of an EF code used to load data into refresh memory in conventional and inventive display consoles.

Depending on bits l-1, 8, and 17, the EF code becomes EF"-L, OA D command, or El"-
TEI or M command, or El”-LOAD
(Command) It is decided whether to load the data from the -L side of the spider refresh memory (L/bottom-down) or from the bottom-up (load from the bottom).

FIG. 4 is a diagram showing how data is loaded into a specific location in the refresh memory specified by the memory address coder.
