A kind of secure and trusted communication unit based on fpga chip

Technical field

This utility model relates to communication unit field, a kind of secure and trusted communication unit based on fpga chip.

Background technology

Along with the fast development of computer technology, information network technique has become as the important guarantee of social development.Information network relates to the numerous areas such as government, military affairs, culture and education.Storage, the many information transmitted and process relate to the important informations such as government macro-control decision-making, business information, bank finance, share certificate, scientific data.Wherein there are a lot of sensitive information, even state secret, so leakage of information, information stealth, data tampering equivalent risk can be faced unavoidably.The computer system particularly network system making us is faced with the biggest threat.Therefore, this problem of information network security is increasingly paid attention to by people, and achieves huge development in recent years.

CPCI(English full name is Compact Peripheral Component Interconnect, and translator of Chinese is compact Peripheral Component Interconnect standard) to have employed PCI(English full name be Peripheral Component Interconnect, translator of Chinese is Peripheral Component Interconnect standard) local bus technology, compare traditional PCI bus and add load capacity.Cpci bus has high opening, high reliability, hot-swappable, makes this technology be widely used in modularity and the applications of high-reliability such as communication, network, intelligent transportation, Aero-Space, water conservancy.Owing to CPCI has higher bandwidth, it is also applied for the field of high-speed data communication, including server, router, switch etc..

Communication unit based on CPCI standard is more and more applied to the communications field, but the security credibility how mentioning the communication unit of application CPCI standard is the technical issues that need to address.

Utility model content

It is Field Programmable Gate based on FPGA(English full name that technical assignment of the present utility model is to provide a kind of Array, translator of Chinese is field programmable gate array) the secure and trusted communication unit of chip, solve how to improve and there is the communication unit of CPCI standard lack safe and reliable problem.

This utility model solves its technical problem and be the technical scheme is that

A kind of secure and trusted communication unit based on fpga chip, including cpci bus interface, P3041 chip, VSC8244 chip, VSC8488 chip, fpga chip, RJ45 interface and SFP+ interface, cpci bus interface is connected to P3041 chip, connect on P3041 chip and have VSC8244 chip and VSC8488 chip, VSC8244 chip and VSC8488 chip are connected to fpga chip, and fpga chip connects RJ45 interface and SFP+ interface.

Described fpga chip includes that (English full name is Configurable Logic Block to configurable logic blocks, be abbreviated as CLB), configurable input output module (English full name be InputOutput Block, be abbreviated as IOB), configurable SRAM type memory module, configurable embedded multiplier (MUL), configurable digital dock manager (DCM) and abundant hierarchy type programmable interconnection.

Described P3041 chip includes 1 ten thousand mbit ethernet controller, 5 Gigabit Ethernet controller, 64 DDR3 Memory Controller Hub of 1 band ECC check and 1 multi-core Programmable Logic Controller.

Also include that DDR3 chip and FLASH chip, DDR3 chip and FLASH chip are connected to P3041 chip.

A kind of secure and trusted communication unit based on fpga chip of the present utility model is compared to the prior art, have the advantages that and have employed domestic FPGA secure and trusted chip, standard RJ45 and SFP optical fiber interface are externally provided, CPCI standard interface is internally provided, can be widely applied on the equipment such as server, storage；This utility model has reasonable in design, simple in construction, the features such as processing, little, easy to use, the one-object-many-purposes of volume that are prone to simultaneously, thus, have good value for applications.

Below in conjunction with the accompanying drawings this utility model is further illustrated.

Accompanying drawing 1 is the structured flowchart of a kind of secure and trusted communication unit based on fpga chip；

Accompanying drawing 2 is the schematic block circuit diagram of a kind of secure and trusted communication unit based on fpga chip.

Detailed description of the invention

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

Embodiment

A kind of secure and trusted communication unit based on fpga chip of the present utility model, its structure includes cpci bus interface, P3041 chip, VSC8244 chip, VSC8488 chip, fpga chip, DDR3 chip, FLASH chip, RJ45 interface and SFP+ interface, cpci bus interface is connected to P3041 chip, connect on P3041 chip have DDR3 chip, FLASH chip all, P3041 chip VSC8244 chip and VSC8488 chip, VSC8244 chip and VSC8488 chip are connected to fpga chip, and fpga chip connects RJ45 interface and SFP+ interface.

Fpga chip is homemade chip SMQ2V6000 series, can support that it is programmed by user according to design requirement.This chip is mainly made up of unit such as configurable logic blocks (CLB), configurable input output module (IOB), configurable SRAM type memory module (BRAM), configurable embedded multiplier (MUL), configurable digital dock manager (DCM) and abundant hierarchy type programmable interconnections.
