Description

A kind of embedded real-time operating system

Technical field

The present invention relates to the communications field, relate in particular to a kind of embedded real-time operating system.

Technical background

TCL (Tool Command Language) was invented in 1980, was a kind of explanation execution script language (Scripting Language), had now become a popular descriptive language; It has an intrinsic core commands collection, supports the flow process control of class C: if control, cycle control and switch control etc., and the definition of supporting process and calling, and powerful array and character string processing capacity is provided.TCL is because of its ease for use, extensibility, and the fast characteristic of complete function and tempo of development has become industry member and tested one of the most frequently used language automatically.

Standard TCL only supports WINDOWS, UNIX/LINUX and three kinds of operating systems of MACINTOSH at present, for some embedded real-time operating systems, as VXWORKS, PSOS, it is not supported, the just impossible integration standard TCL of the system of many like this these embedded real-time operating systems of use; In addition, standard TCL only provides the interface of expansion, but the content of concrete expansion then needs user oneself definition.

Summary of the invention

Purpose of the present invention just provides an embedded real-time operating system that has TCL kernel explanation module, makes it can support most standard TCL functions.

For this reason, the following technical scheme of the bright employing of this law:

Embodiment

Below in conjunction with Figure of description the specific embodiment of the present invention is described.

As shown in Figure 1, it is the structural representation of embedded real-time operating system of the present invention, as seen from the figure, the present invention includes following major part: system interface module, TCL application extension interface module, the embedded TCL kernel explanation module that links to each other with system interface module and TCL application extension module is with the operating system adaptation module that links to each other with above-mentioned module.Wherein:

Described system interface module links to each other with embedded TCL kernel explanation module, and initialization embedded TCL kernel explanation module also starts the interface of embedded TCL task;

Described embedded TCL kernel explanation module links to each other with TCL application extension interface module, receives and handle and carry out the TCL order;

Described TCL expansion connection module provides the application extension of embedded OS;

The operating system adaptation module links to each other with above-mentioned module, finishes the adaptive of native system and other operating systems.

Described embedded TCL kernel explanation module further comprises: syntax check module, command analysis module, command execution module; Described syntax check module is ordered TCL and is carried out syntax check, and check result is sent to the command analysis module; Described command analysis module is ordered TCL and is resolved; Described command execution module is carried out the TCL order according to the command analysis result.

Described embedded TCL kernel explanation module also comprises the one or more combinations in file operation module, process action scope module, control flow module, regular expression module, character string list block and the hash processing module.

Described TCL expansion connection module further comprises: the one or more combinations in test command expansion module, command line interface expansion module, FTP/TFTP loading interface module and the binary file loading interface module.

The interface that described system interface module mainly provides in the embedded real-time operating system embedded TCL kernel of initialization and started embedded TCL task.

Embedded TCL kernel interpreter mainly provides following function: the syntax check of (1) TCL order; (2) parsing of TCL order; (3) definition of intrinsic TCL order and TCL built-in function; (4) execution of TCL order.Wherein file operation module, process action scope module, control flow module, regular expression module, character string list block and Hash table processing module all belong to the definition of intrinsic TCL order and TCL built-in function.Generally speaking, the basic function of embedded TCL kernel interpreter and realization and standard TCL are similar, no longer carefully describe here.

The operating system adaptation module provides the adaptive of embedded TCL and several operation systems, comprise VXWORKS, PSOS, DOPRA etc., make embedded TCL kernel portion and concrete operating system independent, user need only the modification configuration file and just embedded TCL can be used above-mentioned various operating system.

Embedded TCL also provides abundant application extension, comprising: (1) test command expansion module; (2) command line interface expansion module, embedded TCL can be under the situation of log-in command not direct fill order line command; (3) FTP/TFTP loading scripts interface module, embedded TCL can carry out by the script that FTP or TFTP agreement are obtained far-end; (4) binary file loading interface expansion module.

As shown in Figure 2, be embedded OS workflow diagram of the present invention, as seen from the figure, in the process of carrying out the TCL order, whether complete, command analysis, associative operation steps such as command execution if relating to the TCL order.

As shown in Figure 3, be the application synoptic diagram of embedded OS of the present invention in system, as we can see from the figure, system of the present invention can link to each other with physical layer interface and each module by expansion interface, has expanded the system business processing power.

The invention provides the TCL kernel that may operate on the embedded real-time operating system, compare with standard TCL, it can support most standard TCL functions, and its size of code still less, be adapted at using in the embedded real-time operating system, it also is provided at embedded system application extension commonly used: 1, the order line with company's product has level and smooth interface, makes things convenient for the configuration and the test of system; 2, the registration and the second development interface of TCL explosion command are provided, make things convenient for the user in test and diagnosis, to use; 3, provide embedded system binary file loading interface; 4, the function that provides FTP and TFTP loading scripts to carry out; 5, the explosion command of many testing and diagnosings is provided.
