VPX computer processing board based on VITA series standard

Abstract

The invention discloses a VPX computer processing board based on VITA series standards. The VPX computer processing board comprises a COM Express module, a VPX function carrier plate, a panel and a VPX connector, wherein the COM Express module, the panel and the VPX connector are all mounted on the VPX function carrier plate; a VGA signal output from the COM Express module is led to the panel through a VGA interface; the COM Express module is connected with the panel; the COM Express module is connected with the VPX connector through a PCIE bridge; a RaidIO bridge chip is further connected between the COM Express module and the VPX connector; PCIE can be converted into a RapidIO bus through the RapidIO bridge chip; 1 path of PCIE x4 can convert 1 path of RapidIO x4 and is compatible with 1 path of PCIE x1 and converts 1 path of RapidIO x1; conversion of 4 paths of PCIE to 4 paths of RapidIO buss can be achieved at most; 1 path of PCIE3.0 x16 can be converted into 5 paths of PCIE x16 through the PCIE bridge at most; the PCIE bridge is further compatible with PCIE1.0 and PCIE2.0. On the basis of the principle, diverse demands of users can be met, the development period is shortened, and the research expenditure can be lowered.

Description

technical field [0001] The invention relates to the field of computer processing boards, in particular to VPX computer processing boards based on VITA series standards. Background technique [0002] Under the background of the existing technology, there is a growing demand for computer processing boards with large data, large bandwidth and high integration. Currently, there are various technical standards to solve this technical problem. However, in industries such as military and telecommunications that require high reliability, high integration, miniaturization, and strong vibration resistance, the more mainstream solution is the VITA series standard based on the VPX bus architecture. [0003] The VPX bus is based on the VITA series of standards. This standard has implemented multiple versions, and defines multiple versions of different bus and interface resources. Users can choose any version or a part of the interface defined in a certain version for design and use. For...

Problems solved by technology

[0004] However, VPX computer processing boards on the x86 platform are slowly being promoted in the market. Some mainstream x86 computer processing board design companies have only launched 1 or 2 products (usually 3U and 6U each). Or a foreign company

Therefore, even if most of the companies have launched their products to the market, they cannot meet the diverse needs of users, and at the same time, the prices are relatively expensive.

[0005] Since VPX is the mainstream solution for high-speed and large-bandwidth data transmission, but there are many versions of the VITA standard, and the interfaces and buses are extremely rich, large design manufacturers cannot meet so many types of needs, and the controllability of price and cycle time is also very low.
