Description
Technical field
The utility model relates to a kind of large-screen image treatment facility.Be specifically related to a kind of giant-screen processor of the PCI-E of employing bus.
Background technology
Bus is to transmit the common communication main line of information in the computer system between the various functional parts.Bus can be divided into by slot-type: isa bus, pci bus, AGP bus and PCI-E bus.The key technical indexes of bus:
1, bus width (bus data transfer rate)
Bus width refers to the data volume that transmits on the unit interval internal bus, the maximum steady state data transmission rate that promptly every paper money clock transmits.
2, the bit wide of bus
The bit wide of bus refers to the figure place of the binary data that bus can transmit simultaneously, or the figure place of data bus, the notion of highway widths such as promptly 32,64.The bit wide of bus is wide more, and p.s., data transmission rate was big more, and bus width is wide more.
3, the frequency of operation of bus
The working clock frequency of bus is unit with MHZ, and frequency of operation is high more, and the bus operating rate is fast more, and bus bandwidth is wide more.
PCI-E (PCI-Express) bus is up-to-date bus and interface standard, and it is proposed by Intel, transfers to PCI-SIG authentication issue.This new standard replaces existing PCI and AGP comprehensively, finally realizes the unification of bus standard.PCI-E has adopted at present popular in the industry point-to-point connected in series; Shared parallel architecture compared with PCI and more early stage computer bus; Each equipment all has the special use of oneself to connect; Need be, and can bring up to a very high frequency to data transmission rate to whole bus request bandwidth, reach PCI the high bandwidth that can not provide.In the single time cycle, can only realize one-way transmission with respect to traditional PCI bus, two single worker of PCI-E connects the transfer rate and the quality that can provide higher, and the difference between them is similar with half-duplex and full duplex.PCI-E is that a kind of bidirectional linked list connects.Its bus itself is divided into several passages (LANE) again, and each passage is supported the bidirectional data transfers speed of 2.5GbpS.
The PCI-E bus mainly contains following technical advantage:
(1) be universal serial bus, carry out point-to-point transmission, each transmission channel exclusively enjoys bandwidth.
(2) the PCI-E bus is supported transmitted in both directions pattern and data subchannel transmission mode.Wherein data subchannel transmission mode is that x1, x2, x4, x8, x12, x16 and x32 hyperchannel are connected, and x1 one-way transmission bandwidth can reach 250MB/s, and the transmitted in both directions bandwidth more can reach 500MB/s.
(3) the PCI-E bus make full use of advanced point-to-point interconnection, based on the technology of exchange, realize new bus performance and characteristic based on the agreement of bag.
(4) the PCI-E bus makes full use of advanced point-to-point interconnection, has reduced the complicacy and the difficulty of system hardware platform design, thereby has greatly reduced the exploitation designing for manufacturing cost of system, greatly improves the cost performance and the robustness of system.
DVI (Digital Video Interface), i.e. digital visual interface.DVI is based on TMDS (Transition Minimized Differential Signaling; Conversion minimum differential signal) technology is come transmission of digital signals; The encryption algorithm of TMDS uses advanced is encoded to 10bit data (comprising capable field synchronization information, clock information, data DE, error correction etc.) to 8bit data (the every roadbed chrominance signal among R, G, the B) through minimum transition; After the DC balance; Adopt the differential signal transmission data, it has compared Electro Magnetic Compatibility preferably with LVDS, TTL, can use the long distance of private cable realization cheaply, high-quality digital data transmission.The connection transmission structure of TMDS technology is as shown in Figure 1.Digital visual interface (DVI) is a kind of international open interface standard, on equipment such as PC, DVD, high definition television (HDTV), high-resolution projector, is widely used.
VGA (Video Graphics Array) is a Video Graphics Array.It is the computer display standard of using simulating signal that IBM proposed in 1987.The VGA interface is a kind of D type interface, has 15 pin holes above, is divided into three rows, five of every rows.Wherein, except 2 NC (Not Connect) signal, 3 video data buses and 5 GND signals, important is 3 RGB color component signals and 2 scan-synchronized signal HSYNC and VSYNC pin.Chrominance component adopts the RS343 level standard in the VGA interface.The peak of RS343 level standard is 1V.The VGA interface is to use interface type the most widely on the video card, and most video cards all have this kind interface.
CVBS (composite video broadcast singal), it is that an analog television program (picture) signal is combining with voice signal, and is modulated to a kind of form before the radio-frequency carrier.CVBS is the standard that is widely used, and also is called base band video or RCA video, is the conventional image data transmission method of (U.S.) NTSC (NTSC) TV signal, and it transmits data with analog waveform.Composite video comprises aberration (color harmony saturation degree) and brightness (light) information, and with them synchronously in blanking pulse, with same signal transmission.In the ntsc television of scanning fast, very high frequency(VHF) (VHF) or ultrahigh frequency (UHF) carrier wave are the employed adjustment amplitudes of composite video, and this makes the nearly 6MHz of signal of generation wide.Some closed-circuit television systems are used concentric cable short range transmission composite video, and some DVD players and video tape recorder (VCR) provide the composite video input and output through phono jack, and this socket also is called the RCA connector.In the composite video, the interference of aberration and monochrome information is inevitably, particularly in weak output signal.
SDI is " a digital component serial line interface ", i.e. the acronym of digital component serial line interface (Serial Digital Interface).Can be divided into by speed: SD SD-SDI (270Mb/s), high definition HD-SDI (1.485Gb/s) and 3G-SDI (2.97Gb/s).
Giant-screen processor major function is to distribute to N video display unit (like the rear-projection unit) after a complete picture signal is divided into the N piece, accomplishes with a plurality of ordinary video unit and forms a jumbotron dynamic image display screen.Insert when can support various video equipment, as: DVD, video camera, DVB, STB, computing machine.The giant-screen processor can realize that the output of a plurality of physics is combined into a ultrahigh resolution after the resolution stack and shows output, make screen wall constitute a ultrahigh resolution the virtual logical display screen, accomplish kind of signal source windowing on screen wall, move, the Presentation Function of variety of way such as convergent-divergent.
