Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention Specific embodiment is described in further detail.
Fig. 1 show the twinbridge piece configuration diagram of domestic Feiteng processor, as shown in Figure 1, domestic Feiteng processor Twinbridge piece framework, comprising: domestic Feiteng processor A1, low speed bridge piece B1, high speed bridge piece B2, SATA interface D1, network interface D2, USB interface D3 and PCI-E expansion slot D4-D6.
As shown in Figure 1, domestic Feiteng processor is different from existing X86-based processor, its own extended resources is less, Also without matched north and south bridge scheme, the peripheral expansions resouce controllers such as the common USB of computer, storage all fail to integrate.It is domestic Only integrated high-speed PCIE3.0 interface, all peripheral resources are required to be extended by PCIE resource inside Feiteng processor.
Generally high performance 16 core or the 64 core Feiteng processors configured in server, internal integrated two groups of high speeds The interface of PCIE3.0 × 16, every group interface can be split as two groups of interfaces of the PCIE3.0 individually controlled × 8.Server generally needs The function card to be extended such as RAID card, ten thousand Broadcoms and HBA card are the interface of PCIE × 8, certain that display function is wanted The independent display card configured required for the application asked is then the interface of PCIE × 16.
Therefore, consider for above-mentioned extension requirement and upstream and downstream port bandwidth equilibrium, Feiteng processor A1 in the present embodiment Directly go out one group of interface of PCIE3.0 × 16, for the expanded configuration of the interface cards of PCIE × 16 such as independent display card, another set The interface of PCIE3.0 × 16 is split as two groups of interfaces of PCIE3.0 × 8 individually controlled, respectively with low speed bridge piece B1 and high speed bridge piece B2 interconnection, at a high speed with low speed PCIE resource carry out parallel-expansion mode, guarantee upstream data bandwidth while will not be because of bridge piece Between be connected in series and cause performance loss even influence system run all right.
As shown in Figure 1, wherein low speed bridge piece B1 and domestic Feiteng processor A1 is bi-directionally connected by PCI-E2.0 signal, High speed bridge piece B2 is bi-directionally connected with domestic Feiteng processor by PCI-E3.0 signal, and Feiteng processor A1 is corresponding by control PCIE controller realizes the control of corresponding bridge piece.Low speed bridge piece B1 is controlled with SATA controller C1, network controller C2 and USB respectively Device C3 processed is bi-directionally connected by PCI-E2.0 signal;SATA interface D1 and SATA controller C1 is bi-directionally connected by SATA signal; Network interface D2 and network controller C2 is bi-directionally connected by network signal;USB interface D3 and USB controller C3 is believed by USB It number is bi-directionally connected;High speed bridge piece B2 and PCI-E expansion slot D4 and D5 pass through PCI-E3.0 signal respectively and are bi-directionally connected.
As shown in Figure 1, the external I/O interface of low speed includes SATA interface in the twinbridge piece scheme of domestic Feiteng processor A1 D1, network interface and USB interface D2 pass through the PCI-E2.0 signal and domestic Feiteng processor A1 of PCI-E2.0 low speed bridge piece B1 It is bi-directionally connected, realizes the peripheral apparatus of low speed and the communication interaction of domestic Feiteng processor A1;High speed external interface PCI-E extension Slot D4 and D5 is bi-directionally connected by the PCI-E3.0 signal of PCI-E3.0 high speed bridge piece B2 with domestic Feiteng processor A1, is realized The communication interaction of high-speed expansion card and domestic Feiteng processor A1.
As shown in Figure 1, domestic server not only has external I/O interface abundant, can by SATA interface, network interface and USB interface realizes the communication interaction with common peripheral hardware, also offer PCI-E expansion slot, supports standard PCI-E high-speed interface card Extension meets different application environment requirements.Domestic Feiteng processor is different from traditional X86-based processor, its own extension Resource is less, while the north and south bridge nest plate not matched again, all peripheral resources are required to be expanded by PCIE resource Exhibition.
Feiteng processor directly goes out one group of interface of PCIE3.0 × 16 in the present invention, for interfaces of PCIE × 16 such as independent display cards The expanded configuration of card, the interface of another set PCIE3.0 × 16 are split as two groups of interfaces of PCIE3.0 × 8 individually controlled, respectively with Low speed bridge piece and the interconnection of high speed bridge piece guarantee that performance will not be caused because being connected in series between bridge piece while upstream data bandwidth Loss even influences system run all right.Wherein, low speed bridge piece and domestic Feiteng processor are two-way by PCI-E2.0 signal Connection, high speed bridge piece are bi-directionally connected with domestic Feiteng processor by PCI-E3.0 signal, and Feiteng processor is corresponding by control PCIE controller realizes the control of corresponding bridge piece.Low speed bridge piece is logical with SATA controller, network controller and USB controller respectively PCI-E2.0 signal is crossed to be bi-directionally connected;SATA interface is bi-directionally connected with SATA controller by SATA signal;Network interface and net Network controller is bi-directionally connected by network signal;USB interface and USB controller are bi-directionally connected by usb signal;High speed bridge piece with PCI-E expansion slot is bi-directionally connected by PCI-E3.0 signal.
In the twinbridge piece scheme of domestic Feiteng processor, the external I/O interface of low speed include SATA interface, network interface and USB interface is bi-directionally connected by the PCI-E2.0 signal and domestic Feiteng processor of PCI-E2.0 low speed bridge piece, realizes low speed The communication interaction of peripheral apparatus and domestic Feiteng processor;High speed external interface PCI-E expansion slot passes through PCI-E3.0 high speed bridge The PCI-E3.0 signal of piece is bi-directionally connected with domestic Feiteng processor, realizes the communication of high-speed expansion card and domestic Feiteng processor Interaction.
The present invention from hardware view by parallel low speed bridge piece, high speed bridge piece extend respectively low speed external I/O interface and The PCI-E growth data interface of high speed realizes the independent communication of low speed external I/O interface and high-speed expansion interface, both reduces hardware Design cost, and the flexibility of hardware design is promoted, hardware resource is adequately and reasonably utilized, the globality of server is improved Can, there is very strong popularity and practicability.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations Also it should be regarded as protection scope of the present invention.
