Preferably, the step for of described confirmation video card initialization program, the main interface by providing in firmware, obtain initialization program entry address integrated on video card, program length is obtained, by whole initialization program copy to standby in region of memory by analyzing the 3rd byte of this section of program.
Preferably, by in whole video card initialization program copy to region of memory, first apply for that at least 256K memory headroom is for simulating the 256K memory address in X86 platform BIOS, at video card initialization program copy to this section internal memory side-play amount 0xC000, and state that several variablees and array are for simulating X86 CPU depositor, 0xC000 is assigned to the CS segment register of simulation, and the IP depositor of simulation is set to 0x03.
Preferably, the 4th byte that described code parsing module is responsible for from video card initialization program proceeds by parsing；According to the binary data read, search operation code synopsis, confirm the function needing to call and the data needing operation, and the IP pointer of mobile simulation carries out data read operation.
Preferably, described internal memory operation analog module is responsible for the operation of X86 platform internal memory is converted into the corresponding internal memory operation of platform；Call internal memory operation analog module, corresponding handling function call internal memory operation analog module, coordinate incoming parameter to complete the read or write operation of internal memory.
Preferably, described I/O operation analog module is responsible for being converted to X86 I/O operation the corresponding I/O operation of target platform；Call I/O operation analog module, respective function call I/O operation analog module and complete I O read or write operation.
Preferably, if JMP skip command, then call the program execution registers variable that CS, IP simulate by internal memory operation analog module and operate.
A kind of method being applied to realize on domestic non-X86 platform video card initialization of the present invention compared with prior art has the beneficial effect that the present invention passes through simulation X86 CPU on target platform and runs, the program (being provided by video card manufacturer) being stored in advance on video card is provided, complete initialization and the configuration of video card, make domestic non-X86 platform can also be booted up the stage, video card is used to carry out display output LOGO, configuration menu etc., can fundamentally solution during X86 platform computer system is booted up by no means, cause showing the problem such as LOGO and configuration menu because video card cannot be carried out initialization, solve video card initialization and display afunction problem.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, a kind of method being applied to realize on domestic non-X86 platform video card initialization of the present invention is further described.
The present invention proposes a kind of method being applied to realize video card initialization on domestic non-X86 platform, run by simulating X86 CPU on target platform, perform the program being stored in advance on video card, complete initialization and the configuration of video card, make domestic non-X86 platform use video card to carry out display output LOGO, configuration menu etc. in the stage that is booted up, solve initialization and the problem of display afunction of video card in non-X86 platform boot start-up course.
Embodiment:
A kind of method being applied to realize video card initialization on domestic non-X86 platform described in the present embodiment, its key step includes: first confirm that video card initialization program, then by whole video card initialization program copy to region of memory, and call code parsing module, carry out resolving video card initialization program, calling I/O operation analog module, internal memory operation analog module and register analog device, video memory address is mapped in system the most at last simultaneously, by realizing display output function to video memory write data.
This realizes in the method for video card initialization, the step for of described confirmation video card initialization program, the main interface by providing in firmware, obtain initialization program entry address integrated on video card, program length is obtained by analyzing the 3rd byte of this section of program, 3rd byte is the length of this section of program, by whole initialization program copy to standby in region of memory.
This realizes in the method for video card initialization, the step for of by whole video card initialization program copy to region of memory, specifically include that and first apply for that at least 256K memory headroom is for simulating the 256K memory address in X86 platform BIOS, at video card initialization program copy to this section internal memory side-play amount 0xC000, and state that several variablees and array are for simulating X86 CPU depositor, 0xC000 is assigned to the CS segment register of simulation, and the IP depositor of simulation is set to 0x03.
This realizes in the method for video card initialization, described the step for call code parsing module, main contents refer to, the 4th byte that described code parsing module is responsible for from video card initialization program proceeds by parsing, due to the fixed value that the first two byte is specification definition, for verifying, the 3rd byte is program length.
