Description
Technical field
The present invention relates to a kind of programmed method in the computer realm.
Background technology
A variety of programming languages and the programmed method that adopts this language are arranged in the prior art, and like the C language, C++ etc. all have the characteristics of himself; Yet publication number is the computer system that discloses a kind of Chinese programming monolithic processor in the one Chinese patent application of CN1100543, and wherein single-chip microcomputer Chinese programming system has a Chinese dictionary unit, and the explanation of system is accomplished in this Chinese dictionary unit, compiling and operation; Contain the driving of the due equipment of operating system in the dictionary unit, equipment control, file management, order management, explanation, compiling, editor, trace debug etc.; The dictionary identify unit of Chinese neologisms can be multiplied according to the legal inlet flow of text of user's input in this Chinese dictionary unit, and this dictionary identify unit also can be multiplied the new compound word that to comprise this function in read write memory module; That this system adopts is soft-and hard; Integrated design is connected the component address of a readable memory bank and a read-write memory bank overlapping on hardware; Whether reading through bus arbiter decision of the data of two memory banks, this bus arbiter utilize the address on system's " solid speech-＞" unit pointer to judge in two memory banks of selection; Can the dictionary in the read-write memory bank partly be transferred in the only readable memory bank in the application system, simultaneously bus arbiter can select to read and write one of two memory banks according to new mode with " Gu speech-＞".The disclosed programmed method of above-mentioned computer system can't be implemented in the equipment with different CPU and use, and therefore can't realize striding hardware platform, causes the application of this programmed method extensive inadequately.In addition, adopting the programmed method of C and CC++ is at first to compile, and translates into machine code at last, because different CPU has different translation criterias, can't unify, and therefore adopts C and C Plus Plus can't be implemented in the equipment with different CPU and programmes.
Summary of the invention
For this reason, the technical matters that the present invention will solve is to propose a kind of can in having the equipment of different CPU, the use, can realize striding the programmed method of hardware platform.
A kind of programmed method may further comprise the steps:
A. before system initialization, synthesize the interface function object code information of interface function earlier in advance through the instruction of cpu instruction system, the more basic mould of define system;
B. set up dictionary,, and system carried out initialization the basic mould of the said system dictionary of packing into;
C. the dictionary generator with have in the program source code with the speech of said system basic mould same data structure as the expanded mode said dictionary of packing into, in said dictionary, set up information index then, and generate the expanded mode index information to this expanded mode;
D. translater is translated program source code information according to the expanded mode of the said dictionary of packing into;
E. assembler travels through said dictionary, the line data of going forward side by side assembling;
F. after the data assembling, the physical location of pressing the function object code is revised machine call instruction reference address.
Above-mentioned programmed method; Said interface function object code information comprises the interface function index information; With the interface function machine code information that becomes mapping relations with said interface function index information, the data structure of the basic mould of said system is for comprising the basic mould title of system, the basic mould input parameter of basic mould attribute of system and system; The data structure of said interface function index information is interface function object code entry address, interface function attribute, interface function input parameter and the interface function status indicator that comprises the interface function name, is used to represent said interface function object code information space position; The basic mould of said system has the basic mould member function of system; The basic mould member function of said system has system's basic mould member function index information, and the data structure of this index information is to comprise system's basic mould member function name, system basic mould member function object code entry address, system's basic mould member function attribute and the basic mould member function of system's basic mould member function input parameter and the system status indicator that becomes mapping relations respectively with said interface function name, said program function object code entry address, said interface function attribute, said interface function input parameter and said interface function status indicator.
Above-mentioned programmed method; Among the said step b system is carried out the information index that initialized step is specially the member function of in dictionary, setting up the basic mould of said system; And the corresponding system of the interface function index information basic mould member function index information described in generation and the step a, more said program function object code entry address is stored in the relevant position of information index.
Above-mentioned programmed method; Said expanded mode comprises expanded mode member object and expanded mode member function, and the data structure of the member function of said expanded mode is for comprising and system basic mould member function name, system basic mould member function object code entry address, system's basic mould member function attribute, the basic mould member function of system's basic mould member function input parameter and system status indicator corresponding expanded mode member function name, expanded mode member function object code entry address, expanded mode member function attribute, expanded mode member function input parameter and expanded mode member function status indicator respectively; Said expanded mode member function comprises operational symbol and/or generic function; The data structure of said expanded mode member object is expanded mode member object data entry address, expanded mode member object attribute and the expanded mode member object status indicator that comprises expanded mode member object name, is used to store the expanded mode member object.
Above-mentioned programmed method; The translation steps of translater is specially: translater is according to expanded mode member function entity text position address information in the said dictionary; From the program source code text, transfer the entity text, said entity text is the said contamination in the said dictionary of packing into; And said entity text translation become the code information of expanded mode member function target machine; The interim storage space of in computing machine, opening up simultaneously, and be that base unit deposits said interim storage space in the program file with the code information of said expanded mode member function target machine; Said interim storage space has interim storage space entry address information, makes said interim storage space entry address information become mapping relations with said expanded mode member function object code entry address information;
