Abstract

PURPOSE:To eliminate an intermediate medium and at the same time to save labor by extracting the prescribed information out of information transmitted from a host computer. CONSTITUTION:The control signals, i.e., a command and data which are transmitted from a host computer and then written to an EPROM are received by an interface 7 and stored temporarily in a buffer memory 8. A command analyzing part 9 recognizes both control signal and data which are written to the EPROM and supplies the control signal to an EPROM control part 15. The part 15 stores the data to an RAM 16 from the memory 8 in accordance with the given control signal. At the same time, the part 15 writes the data stored in the RAM 16 to an EPROM 17.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a data processing system, such as a TSS system, which has a function of connecting a terminal device to a host computer and performing interactive processing.

Extracts predetermined information from the host computer's output information,
This relates to a terminal device that directly stores the data in a FROM (Fixed Memory Element).

(B) Background and Problems of the Invention In general, the process of designing using a terminal color simulation system connected to a post computer and writing the obtained results to FROM is often performed.

However, conventionally, as shown in FIG.

The method of designing while communicating with a host computer 1 using a terminal device 3 having a Te3 (time shearing) function and storing the results in a FROM is generally performed offline. in this case.

Information data after designing and simulating etc.

The terminal device 3 records the information on a paper tape or floppy disk, which is an intermediate medium 4, and the contents of this paper tape or floppy disk.

A separate dedicated PROM writer 5 was used to store the data in a FROM, such as an EPROM. The FROM created in this way was mounted on the controlled device as shown in 6, tested, and the above process was repeated as necessary.

As mentioned above, the content designed via the terminal device is first recorded on the intermediate medium, and then recorded on the FROM (2). There were other problems.

(q Object and Structure of the Invention The present invention is a data processing system having a host computer and a terminal, in which predetermined information is extracted from information sent from the host computer, and the data is directly transferred to FROM +
By storing information, the purpose is to eliminate the need for intermediate media such as paper tapes and floppies, and to save time and effort. Therefore.

The present invention provides a data processing system having a terminal function connected to a host computer, in which the terminal device includes a receiving section that receives control information and data sent from the host computer, and a command signal from the signal received by the receiving section. υ characterized by comprising a command analysis section for detecting a command, and a storage control section having a function of storing the data in FROM based on a signal from the command analysis section.
).

0 Embodiments of the Invention The present invention will be described in detail below with reference to nine drawings.O FIG. 2 shows the configuration of one implementation of the present invention, FIG. 3 shows a control data information diagram according to the present invention, FIG. 4 shows a processing flow diagram according to the present invention.

In FIG. 2, the terminal device is a transmitting/receiving interface 7.
The computer is connected to a host computer 1 having T88 functions via a communication line, etc., and processes such as simulations are performed in a conversational manner.

The signals sent from the host computer are sent via the interface 7) (sofa memory (or register) 8 (
2.The command analysis unit 9 analyzes the content and converts it into the analyzed result; 5X, the control signal is sent to the corresponding display control unit 10. Keyboard control unit 13. The data is also supplied to the EPROM control unit 15 and the like according to the present invention. The display control section 10 displays information sent from the host computer 1 and the like and data input from the keyboard control section 13 on the CRT 12 . The keyboard control unit 13 sends data input from the keys 14 to the display control unit 10, and
:c - Send 1fff to the host computer by Suffu
Ru. The EPROM control unit 15 writes data to the RAM 16 or EPROM 17 of the storage element. RAM16
This is the case when the EPROM control unit 15 repeatedly writes data to the EPROM 17i.

It also stores information for write control.

4 Design is done interactively with the computer 1 using the CRT 12 and keys 14).

The contents are simulated using simulation program 2 (2).The results obtained in this way are
The OM control unit 15 can record the data in the BP and ROM 17.

The control signals, ie commands and data for EPROM+-framing sent from the host computer are:
It is received from the interface 7C2 and temporarily stored in the sofa memory 8. The command analysis unit 9
It recognizes that the control signal and data are for OMc writing, and supplies the control signal to the EPROM control unit 15.

Based on the given control signal, the EPROM control unit 15
Data from the buffer memory 8 is stored in the RAM 16, and data b) stored in the RAM 16 is stored in the BP
ROM1 7 +-Write.

As explained above, according to the present invention, after designing and simulating the TSS system while talking to the host computer 1 using the terminal device of the TSS system, the contents are transferred to EP and RO.
M etc. (= can be memorized easily and quickly.

FIG. 3 shows the format of control data according to the present invention.Start command 19. It consists of data 20° and end command 21. command.

When the analysis unit 9 detects the start command 19, the analysis unit 9
PROM control unit 15 (supplies two control signals).

The EPROM control unit 15 stores the start command 19 and the data 20 received in succession in the RAM 16f. Next, when the command analysis section 9 detects the end command 21, it stops supplying the control signal to the EPROM control section 15. As a result, the EPROM control unit 15 stores the data signal and stores it in the EPROM 17 according to a predetermined procedure.

FIG. 4 is a processing flow diagram according to the present invention.

A flowchart is shown when the command analysis section 9 performs the operation described in connection with FIG. 3.

The command analysis unit 9 receives identification information 9 which is a start command 19, for example 'DATA RECEIVESTAR
If TED,,'FF...F F is detected (YES), the identification information ■ which is the end command 21.

For example, until 1) is detected (YES), the data is stored in the RAM and the stored data is written into the BFROM. The storage and EFROM write ends when an end command is detected. After completion, conventional processing is performed. Further, if the identification information that is the start command 19 is not detected (No), conventional processing is performed.

Note that the present invention is not limited to storing in EPROM, but may also be stored in other types of FROM. can be detected and the contents can be written directly to FROM.This eliminates the need for intermediate media such as paper tape as in conventional methods, allows for simple and quick writing, and allows only the information required by the terminal device to be written. This has the effect of not impairing other TSS functions.Specifically (- direct FRO without intermediary medium)
Since writing is performed in M, there is a great effect that errors in written information are reduced and no human intervention is required.
