Summary of the invention
The present invention proposes a kind of computer organization that hyperchannel shows single whole desktop that is used to export, can realize that the output of computing machine ultrahigh resolution hyperchannel shows a complete desktop picture picture, guarantee that simultaneously system resource takies seldom when showing the ultrahigh resolution whole desktop, whole computing machine speed of displaying can be therefore not slack-off.
The present invention is achieved by the following technical programs: a kind of computer organization of many output display channel single whole desktops, comprise,
Empty screen processor, be used for computer desktop resolution retention system main memory according to required generation, in described system main memory, generate and preserve the virtual computer desktop bitmap, and after described virtual computer desktop bitmap is carried out piecemeal and is compressed into compressing image data, described compressing image data is transferred out by the contact medium;
The contact medium is used to finish the communication between each output channel of described empty screen processor and each video-stream processor;
The video-stream processor of many output channels more than two, each video-stream processor is respectively applied for and receives the described compressing image data corresponding with this video-stream processor, and by showing counterpart in the described virtual computer desktop bitmap in a plurality of output channels of this video-stream processor behind the decompress(ion).
The present invention proposes a computing machine and generate virtual multi-screen desktop, other many computing machines show respectively, realize that the output of computing machine ultrahigh resolution hyperchannel shows a complete desktop picture picture, picture surpasses the 100M pixel, output channel can reach more than 130; Guarantee that simultaneously system resource takies seldom when showing the ultrahigh resolution whole desktop, the speed of whole computing machine can be therefore not slack-off.

Embodiment
Empty screen processor generates a virtual computer desktop bitmap in its system's main memory, by the general transmission agreement virtual desktop data transmission is gone out after to Image Data Compression and piecemeal.Empty screen processor is a computing machine that abundant system main memory has been installed.System's main memory is mounted in the memory bar on the computer motherboard, the necessary storer that is computer operating system when operation.The highest virtual desktop resolution of requirement generation and operating system were to the basic need decision of amount of memory when the system's main memory quantity that need install was moved by void screen processor.Such as, on an empty screen processor, moved WINDOWS XP professional version operating system, needing to produce highest resolution is 32 color depth virtual desktops of (1024x26) x (768x5), then need 390MB system main memory and be used to preserve the virtual desktop bitmap, use 256MB to calculate during according to operating system, the system's main memory quantity that need install is 646MB (being 390+256) much.
Utilize the memory management mechanism of WINDOWS operating system, operating system is only operated on the part system main memory, simultaneously, virtual desktop resolution as required keeps system's main memory of sufficient amount (computing method as previously mentioned).This part system's main memory is used to the computer desktop bitmap of storing virtual, by display driving software management and use.
The display driving software that can produce the ultrahigh resolution virtual desktop is followed the USBDI standard of WINDOWS operating system, and main development tools is WINDOWS 2000/XP DDK and Visual C++, is designated hereinafter simply as virtual display driver.Virtual display driver and other display driving softwares have clear and definite difference technically, and as virtual display device, and other display driving softwares are at the exploitation of specific graphic display card to virtual display driver with system's main memory.Virtual display driver calls kernel function MmMapIoSpace when initialization, system's main memory that will be used for virtual demonstration is mapped to virtual address space, afterwards, realizes the display driving software interface function of oneself with the same method of normal display driving software.When realizing each display driving software interface function, to make to be saved on system's main memory by the demonstration desktop picture that the display driving software interface function generates from virtual address space address that system's main memory maps out as the display memory pointer by operating system.
Virtual display driver is preserved and is shown desktop picture in system's main memory, and has realized being used for the DrvEscape interface function supply routine call of Image Data Compression and piecemeal.Application program is compressed and piecemeal the virtual demonstration desktop picture of the ultrahigh resolution in system's main memory data by calling the DrvEscape interface function of virtual display driver, by the general transmission agreement virtual high resolving power desktop is transferred out again.
Video-stream processor receives from carrying out decompress(ion) behind the compressing image data on the void screen processor, then the parts of images that has changed is refreshed, and the part that does not change will not carried out refresh operation.Because video-stream processor only carries out the part and refreshes, so refresh rate is very fast, has effectively guaranteed the image display performance of computing machine.
Fig. 2 is a kind of computer organization instance graph that utilizes the present invention to realize, empty screen processor is a common computer based on WINDOWS operating system among the figure, by generate the desktop of a width of cloth 100M pixel graphics resolution behind the virtual display driver at internal memory, these desktop data are through overcompression and piecemeal, by ICP/IP protocol, on network, transmit (also can come communication as the physical medium that USB or i1394 have host-host protocol) with other through the gigabit networking switch.
Each video-stream processor is a computing machine with hyperchannel Presentation Function, each video-stream processor can have 1 to 32 (even more a plurality of) output channel, after each video-stream processor receives the control signal that empty screen processor sends, begin to receive the compressing image data corresponding that empty screen processor transmits with each video-stream processor from network, and by on 1 to 32 output channel of each video-stream processor, showing away behind the decompress(ion), like this, the figure of the 100M ultrahigh resolution of empty screen processor generation will complete the showing by the output terminal of all video-stream processors.
