Detailed Description
The detailed description of the embodiments of the present invention is provided in conjunction with the summary of the invention and the accompanying drawings.
Firstly, system topology design: the data exchange bus topology of the invention is shown in figure 1, the SRIO bus network topology in the unmanned command control network is a star-shaped distributed architecture taking a high-speed real-time SRIO switch as a center, each node is equal, and the network can be accessed through a terminal provided with an SRIO node card.
Second, SRIO switch design
The module for realizing the switching function in the SRIO switch is called as the SRIO switching core module for short. The SRIO switching core module needs to provide a 24-way SRIO switching function to the outside. A single switch chip does not fulfill such a requirement. Therefore, the number of the switching ports is expanded by adopting a cascading mode to realize 24-path SRIO switching.
The scheme is designed by adopting a 2-chip second-generation SRIO switching chip CPS1848(18 ports). The 24 port SRIO switch is initially designed. The block diagram of the SRIO switch design is shown in fig. 2:
the CPS1848 switching chip is designed to realize the antithetical couplet through 2 sets of SRIO links at 5Gbps for cascading extension.
Each CPS1848 switching chip is designed to externally lead out 12 paths of SRIO, 2 CPS1848 switching chips realize 24 external SRIO ports in total, and the speed of each SRIO link is 1.25 Gbps. Each SRIO port is interconnected with 1 optical module inside the module. The 24 optical modules are placed on a panel of the SRIO switch, and connection is convenient.
The SRIO switch is designed by adopting a 2U rack type 19-inch standard rack-mounted chassis, and the height is multiplied by the width and multiplied by the depth to be 88.9mm multiplied by 482.6mm multiplied by 500 mm. The function of the switch is split by considering the height and the width of a panel of the case, and the switch is designed to be composed of an SRIO switching core module, an optical fiber IO board, a back board, a power supply module and the case.

The SRIO exchange core module mainly completes the exchange of the SRIO protocol packet and realizes the unicast and multicast functions of 24 ports. The module adopts a VPX 6U card structure, is convenient to install and disassemble and is convenient for function upgrading.
The 24 paths of SRIO interfaces are led out to the VPX connector in an electric signal mode and are interconnected with the optical fiber IO board through the VPX back board.
b) Optical fiber IO board
The optical fiber IO board mainly realizes the conversion between SRIO high-speed serial electric signals and optical signals. Each IO board can be designed to realize 12-path single-mode optical modules. 2 fiber IO boards need to be designed.
A26-core J599 series optical fiber connector with the model number of J599/20KE26A1N-G is selected, and 2 optical fiber connectors are used. The shell number E of the J599/20KE26A1N-G connector can be provided with 26 cores 16# of optical contacts. Each connector is designed to provide 12-way integrated transceiver fiber links. The J599 series fiber optic connector is mounted on the rear panel of the SRIO switch. External interconnection is facilitated.
And the optical fiber jumper is customized to realize the optical fiber interconnection of the optical fiber IO board and the J599 connector (aerial plug) of the rear panel.
c) VPX back plate module
The VPX backplane mainly realizes interconnection of an SRIO switching core module or an optical fiber rear rotating plate and provides +12V power supply.
d) Power supply module
The power supply module meeting the CPCI standard is selected as an internal power supply of the SRIO switch, the power supply conversion from AC220V to DC +12V can be realized, the conversion efficiency is generally 75%, and the installation and the disassembly are convenient.
Third, SRIO node card design
The SRIO node daughter card has the main function of realizing protocol bridging between PCIe and SRIO. The card is connected with an X86 host module through a VPX connector (interface is PCIe); the other end is connected with the SRIO switch through an optical fiber.
The functional block diagram of the SRIO node daughter card is shown in fig. 3:
the SRIO node daughter card is implemented by the FPGA of Xilinx. The switching and processing from PCIe protocol to SRIO protocol can be completed through FPGA, and the design is flexible. According to the scheme, a Xilinx high-performance Kintex-7FPGA (XC7K325T-2FFG900I) is selected as an SRIO node main chip, and the line rate of a high-speed GTX interface of the FPGA chip can support 6.6Gb/s at most. And the speed requirements of the second generation SRIO and the second generation PCIe are met.
A1-path PCIe interface is led out from the FPGA, the speed is 1.25Gb/s, and the PCIe interface is connected to a VPX connector of an SRIO node daughter card and used for being connected with an X86 host to enable the X86 host to receive and send data or instructions.
A1-path SRIO interface is designed to be led out from the FPGA, the speed is 1.25Gb/s, the SRIO interface is connected to an optical module, and the optical module is used for realizing the mutual conversion between electric signals and optical signals. And finally, the SRIO switch is connected through the optical fiber to realize the optical fiber link of the SRIO protocol.
The FPGA is designed to be externally connected with 1 x16 or x32 DDR3SDRAM memory for data caching.
Inside the FPGA, corresponding logic is developed to implement bridging of the PCIe protocol to the SRIO protocol.
Four, self-defined frame format
In order to ensure the stability of data transmission, all ports in the SRIO switching network use a uniform data message format to perform data transmission. The self-defined frame format is composed of a data header FrameHead and data Payload, and the maximum transmission length is (64Byte +4032 Byte). The data per transmission cannot exceed the maximum transmission length. The frame format is shown in fig. 4:
from a design implementation perspective, the maximum data length is supported up to 4 KByte. The maximum length of each packet data is 256 bytes due to the SRIO. If the data length exceeds 256 bytes, the 4KB data message is split into data sizes which accord with an SRIO protocol to be transmitted and received, and the specific unpacking function is realized by an FPGA of the terminal.
a) Message header format
In order to conveniently expand the functions of the Data message, the length of a Data message header is defined to be 64 bytes, and the effective fields involved in the scheme are four fields of source ID, Dest ID, flag and Data length. Fig. 5 is a header format definition:
b) field definitions
a) source ID: the device ID of the sender;
b) dest ID: receiving the device IDs of all devices;
c) flag: marking the state and the attribute of the current message;
d) reserve: reserving fields for expansion;
e) data length: and marking the effective data length of the current data message, wherein the unit is Byte.
Fifth, the configuration of the switch
a) Route configuration
In the RapidIo network, the key parameters of the route configuration include: the device ID, often denoted DevID, that needs to access the device; the number of routing hops, denoted hop count. Wherein DevID is the unique identification of the device in a RapidIO network, corresponding to the MAC address in an IP network, and the same DevID cannot be found in the same network. The hop count is the number of switches which a data packet in the RapidIO network needs to pass through when being sent from the original DevID to reach the destination, and the hop count is automatically reduced by 1 when passing through one switch until the number is zero, and the transmission is terminated.
In the process of configuring the Route, it is actually a resident controllable specific memory block in the write switch, and it is a one-to-one correspondence two-dimensional index Table of the memory block and the PORT of the switch where it is located in some way, usually described as LRT (Look-up Route Table) in the switch manual. In a small network, this is a 256byte block of memory where the relative 0 to 255 addresses correspond to the DevID of the endpoint and the PORT number corresponds to the value of the relative address to the DevID.
b) Multicast configuration
In order to solve the problem that a data sender sends one copy of data to a plurality of SRIO receivers at a time in the SRIO, a multicast mechanism is required. The SRIO switch supports multicast routing configurations. A Multicast Dest ID belongs to a Multicast group and is forwarded to any member of the Multicast group. Thus, the data sender only needs to transmit the data once, and the data sender can automatically transmit the duplicated copies to other members in the multicast group by the switch. Using the multicast function, one or more multicast groups need to be created first, and then members are added to the multicast groups to complete the establishment of the multicast groups. When a specific source in a multicast group sends data, if the switch detects that the data is multicast data, the switch will not route the data, but copy the data into the data of the multicast group members and send the data to corresponding node cards respectively.
c) SRIO network configuration
The switch scans the whole rapidio network according to a predicted rapidio network topological graph planned in advance and configures the equipment ID of each node;
configuring a switch multicast group and distributing multicast ID;
the node card completes the filling of the self-defined frame header content to realize the multi-functional multicast function of the user.
Sixthly, a data receiving and transmitting mode example: according to the transmission flow direction of various messages and data in the unmanned command control system, the unmanned command control information exchange mode is divided into unicast and multicast, wherein, taking the establishment of 4 multicast groups as an example, each group distributes one type of data. The SRIO data transceiving block diagram is shown in fig. 6:
a) port 1-3 to port 18, 19 data transmission
Any one of the ports 1-3 sends multicast data to the multicast group 1;
after receiving the data, the multicast group 1 distributes and respectively sends srio data messages to the ports 18 and 19 according to the configuration of the multicast group;
the ports 18 and 19 receive srio data; and forwards the data to the upper computer.
b) Port 18, 19 to port 1-3 data transfer
Any port of the ports 18 and 19 sends multicast data to the multicast group 2;
the multicast group 2 distributes and respectively sends srio data messages to ports 1-3 according to the configuration of the group;
port 1-3 receives srio data; and forwards the data to the upper computer.
c) Data transmission from port 4-17 to port 18, 19
Any one of the ports 4-17 sends multicast data to the multicast group 3;
the multicast group 3 distributes and sends srio data messages to the ports 18 and 19 respectively according to the configuration of the group;
the ports 18 and 19 receive srio data; and forwards the data to the upper computer.
d) Port 18, 19 to port 4-17 data transfer
Either of the ports 18, 19 sends multicast data to the multicast group 4;
the multicast group 4 distributes and respectively sends srio data messages to ports 4-17 according to the configuration of the group;
port 4-17 receives srio data; and forwards the data to the upper computer.
