CONSTITUTION:A host machine 1 and a target machine 7 of a minicomputer which contains a CPU 3, a main storage device 4, a large capacity storage device 5, etc., and has a function for a data generation and a compiler of a program are connected by a bus 12 through the respective inter-device connecting devices 2, 8 and allowed to take an interface to an address bus. In such a state, data and a program of a compiler language generated by the machine 1 at high speed without using an external storage device are supplied to the machine 7 and the machine 7 operates without using a machine language. On the other hand, based on the data from the machine 7, an operating state of the machine 7 is verified in a real time by the machine 1. As a result, operation of the system at high speed, improvement of a data quality by a real time verification of the operation of the machine 7 are executed, and to the debug processing of the machine 7 is executed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a four-host target machine system that integrates a separate host machine and target machine.

[Prior Art] Conventionally, in a system consisting of a host machine and a target machine, programs and data created on the host machine are supplied to the target machine via an external storage device such as a magnetic tape or a disk pack. was.

[Problem to be solved by the invention M] However, in conventional systems, it takes time to transfer programs and data created on a host machine to a target machine via an external storage device.
It took a lot of time to modify programs and data. In addition, when debugging on the target machine, since the programs and data on the target machine are in machine language, it is not possible to immediately modify the programs and data created with a compiler in the form of a source image. However, since verification cannot be performed immediately on the target machine, shortening the debugging period and improving the quality of the software cannot be expected.

[Means for Solving the Problems] The technical means of the present invention for solving these drawbacks is a host/target machine system that integrates a host machine and a target machine, in which, as the host machine, data A minicomputer is used that has the function of creating programs and compiling programs, and the host machine and target machine are each equipped with an inter-device connecting device that is connected to each other and interfaces with the address bus of the target machine. A host/target machine system that supplies data and programs created by a computer to a target machine via an inter-device connection device.

[Embodiment] Hereinafter, a host/target machine system according to an embodiment of the present invention will be explained based on the accompanying drawings. FIG. 1 is a configuration diagram of a host/target machine system according to an embodiment of the present invention. In the figure, 1 is a host machine, and a minicomputer is used. 2 is an inter-device connection device on the host machine 1 side, and is connected to the target machine 7.
It has the ability to interface with the address bus of 3 is the central processing unit of the host machine 1 which is connected to the inter-device connection device 2 via the bus 13 and processes programs and data; 4 is the main memory of the host machine 1 for programs and data; and 5 is the main memory of the host machine 1 for programs and data. A large capacity storage device of the host machine 1 stores data, and 6 is an input/output device of the host machine. 7 is the target machine, and the bus 12 is connected to the inter-device connection device 2 of the host machine 1.
The target machine 7 has an inter-device connecting device 8 connected thereto to interface with the address bus of the target machine 7. Reference numeral 9 denotes a central processing unit of the target machine 7 connected to the inter-device connecting device 8. 10 is a main storage device of the target machine, and 11 is an auxiliary storage device of the target machine, which are connected to the inter-device connection device 8 and the central processing unit 9, respectively.
via a bus 14.

Next, the functions of the host/target machine system according to this embodiment will be explained according to a flowchart. When transferring programs and data from the host machine 1 to the target machine 7, as shown in the flowchart shown in FIG. (2-1). Next, in the central processing unit 3, the program and data are sent to the inter-device connecting device 2 via the bus 13 (2-2). Thereafter, the program and data are sent from the host machine 1 to the target machine 7 via the inter-device connection device 2.8 (2-3). As a result, the inter-device connection device 8 of the target machine 7 fllll+ stores programs and data in the main storage device 10 or the auxiliary storage device 11 according to instructions from the host machine 1.

FIG. 3 is a flowchart showing the procedure for collecting the operation contents of the target machine 7 without affecting the operation of the target machine 7, transferring it to the host machine 1, and displaying the operation status of the program. . In this case, first, the register contents and memory contents, which are the operating status of the central processing unit 9 of the target machine 7, are collected by the inter-device connection device 8 on the target machine 7 (3-1
). Next, this collected information is transferred to the inter-device connection device 8.2.
(3-2). The host machine 1 transfers the information from the target machine 7 to the central processing unit 3 on the host machine 1 (
3-3). In the central processing unit 3, this information is stored in the main storage device 4 or mass storage device 5 (3-4)
Thereafter, the central processing unit 3 displays the stored information via the input/output device f6 (3-5).

[Effects of the Invention] As explained above, according to the host/target machine system of the present invention, the modification or creation of information in machine language on the target machine can be handled using the compiler language on the host machine. I can do it. In addition, by collecting the operating status of the target machine on the host machine and comparing it with the source image on the host machine, debugging can be performed in a compiler language that is easier to understand for humans than machine language, improving the efficiency of debugging. You can expect it. Furthermore, for systems exported overseas, programs and data can be easily created on-site, making it possible to significantly shorten the construction period.
