Abstract

The program enables operators to terminate a running program at any time, and execute several debugging commands in the multi program running state, at the on-line remote sites. The operating principle comprises: an input character is examined whether a special character which is assigned as a character to re-prompt the debugging monitor. If not, check whether it is a terminating character, and them, terminates an interrupt process. This debugging monitor is useful in the multiprocessor based ESS (electronic switching system) for the effective control and maintenance.

The present invention relates to a method in which a ROM resident monitor debugger (hereinafter referred to as a debugger) mounted on and operated by a board of a high-level processor and a low-level processor of an electronic switchgear receives and executes its own instructions.

The debugger mounted on each board verifies the function of the board at startup and allows the user to load the user program into the main memory using debugger commands, or the user directly enters the program into the main memory, and then executes and executes the user program. Create an environment where you can search for errors.

Conventionally, the instruction execution control of a debugger having a command interpreter driven in a polling manner in this form has been configured in such a manner that it is ready to accept a new debugger instruction after the processing for the currently executing debugger instruction is completed. When using the polling method, once the user has executed a user program using the debugger command, the execution of the user program has reached the end of the execution breakpoint already specified using the debugger command or the execution of the user program is terminated. In the former state, that is, while the user program is running, there is no way to input a debugger command or stop the running user program except by pressing a mechanically configured reset button.

Accordingly, an object of the present invention is to solve the problems of the prior art, and to change the character input method of the debugger mounted in the electronic switchboard to the interrupt method, thereby recognizing the command input items and driving the command interpreter. The present invention provides an online method of operating a debugger command interpreter that enables a debugger command interpreter to accept and execute another debugger command even when one command of the debugger is being executed. In other words, even if the user program is infinitely executed, the user can input the debugger command and control the execution of the user program during execution of the user program without waiting for its execution to be completed. To make In addition, when a user program detects a malfunction of the program and wants to stop the execution, the distant board can be simply processed by the user inputting the special character promised without pressing the restart switch.

In order to achieve the above object, the present invention will be described in detail with reference to the accompanying drawings. 1 is a hardware configuration diagram to which the present invention is applied. In the drawing, (1) is a high level processor (MP), (2) is a low level processor, and (3) is a signal message processor for processing a NO.7 signal message. SMHP), (4) Main Board (MPMA), (5) Lower Level Board (PPPA), (6) CPU, (7) Multi-Function Peripheral (hereinafter referred to as MFP), 8 denotes a debugger, 9 denotes a main memory, and 10 denotes a monitor.

The upper level processor (MP) 1 includes a matching exchange processor (ASP), a number translation processor (NTP), an internal network processor (INP), an input / output control processor (MMP), an operation and maintenance processor (OMP), and the like. There are the same things. The low-level processor 2 includes time division switch processor (TSP), space division switch processor (SSP), voice service processor (GSP), analog subscriber matching processor (ASIP), analog relay network processor (ATIP), and digital. Trunk Line Processor (DCIP), Digital North American (T1) Trunk Processor (DTIP), Signal Service Processor (LSP), Line System Maintenance Matching Processor (ASMP), Central Control Maintenance Matching Processor (CCMP), Synchronous Processor (NSP) ), Central link matching processor (CLIP), network maintenance matching processor (INMP), and link matching processor (LLIP). In each board 1, 2, 3, the CPU 6 has arithmetic and control functions of the MFP 7, and a reference function for the main memory, and the MFP 7 has board input / output and interrupt activation. Has the function of determining the presence or absence. The use of the main memory 9 has a function of storing user programs and data.

2 is a flowchart of a debugger using a conventional polling scheme. When power is supplied to the board, the debugger 8 is automatically operated to check the function of the central processing unit 6 (11). If abnormal, the start of the debugger 8 is stopped. If the state of the central processing unit 6 is normal, the read / write function of the main memory 8 is checked and the contents of the main memory 9 are erased (12). Thereafter, the MFP 7 is initialized to perform character input / output in a polling manner (13), the initialization of the execution data of the debugger 8 and the execution environment (14), and the user inputs a debugger (8) command. While waiting (15) for a full sentence debugger (8) command is input (16), the debugger (8) to perform the function of the debugger (8) corresponding to the input debugger (8) command is performed ) Drive the command interpreter (17). After the execution of the user input debugger 8 command is completed, the debugger 8 is ready to accept the next command and goes back to the debugger 8 command input state. As can be seen in the above process, it is inconvenient to input another command in a state before the execution of the command input by the user is terminated, that is, the debugger 8 command is being executed.

3 is a flowchart of the debugger 8 to which the present invention is applied, which shows that the operation of the debugger 8 command interpreter is brought online by supplementing the problems of the prior art.

The function of the central processing unit is checked (31). If abnormal, the start of the debugger 8 is stopped, if normal, the main memory is initialized (32), and the character input is performed by using an interrupt. Initialize the function (33). The environment of the debugger 8 is then initialized (34) and enters a state waiting for the user to enter text (35). At this time, when one character is inputted, a character input interrupt is generated to start the interrupt processing routine, and after the character input interrupt processing routine is completed, the character input interrupt is returned to the execution point at the time when the character is inputted. When an input character is generated, the debugger recognizes it (36), checks whether the input character is a special character requiring restart of the debugger 8 (37), and if it is a restart request character, processes the matter for restart (38). ), Branch to MFP 7 initialization step 33 and restart debugger 8. That is, after the user inputs a certain debugger 9 command to start its function, it has a function of forcibly canceling its execution while performing the function of the debugger 8 command. If the input character is not a character requiring a restart, it is determined whether the character indicates the end of the command line (39), and if it is not the end character, the debugger (8) keeps the input character in an area for storing the command line (40). The character input interrupt processing function is terminated (41). If a character indicating the end of the command is input, the debugger 8 command interpreter is notified of the area in which the previously entered letters are stored to execute the command interpretation and the function corresponding to the input command (42). When the function execution of the input command ends, the character input interrupt processing function is also terminated. The execution point then returns to the point where the command termination character was entered.

Accordingly, the present invention made up of the above-described processing procedure enables the user to load the program into the main memory device and to execute the program by inputting a debugger command for controlling the execution of the program or checking the execution status even while executing the program. There is an application effect that can increase the convenience and efficiency of the debugger.
