Embodiment

[0045] Take a new generation of VPX ruggedized computer developed by a company as an example. The system includes multiple computing units, GPU units, radar data processing units, image processing units, and so on. Such as Figure 4 As shown, according to the use method of the present invention, the module types are first classified according to the functions and performance of all resource modules, and the use requirements of each module in the system are clarified. Using CPS1848DS as the main chip, designing SRIO switching modules, building a star topology switching architecture in the system, and integrating various resource modules on the physical layer. According to the step method of the present invention, each resource module is assigned a unique identification number, from slot 1 to slot 16. After completion, the integrated management module is operated in accordance with the IPMI standard, and the size of the physical address space that needs to be allocated and exchan...

Abstract

The invention discloses a data distribution method based on SRIO global memory sharing, which adopts an SRIO exchange mode based on a star architecture and is mainly applied to systems such as a multi-unit server, a multi-computer module group, a multi-computing unit workstation, a multi-computing unit graphic workstation, a multi-resource data sharing platform and the like. Distributed calculation of big data calculation is mainly realized, a global memory is shared, the resource utilization rate and the calculation efficiency are improved, and the high efficiency and the real-time performance of data and image processing in the system are effectively improved.

Description

Technical field [0001] The invention relates to a data distribution method based on SRIO global memory sharing. Background technique [0002] Embedded rugged equipment designed based on computer systems has now been widely used in various occasions. With the increase in system complexity, the demand for computing speed, capacity storage, and function expansion is also increasing, especially in military applications. , Aviation, aerospace, telecommunications and other fields. In this case, the traditional independent unit computer architecture can no longer meet the current system requirements. Therefore, a new computer system based on serial bus technology is quietly emerging. There are many types of serial buses. Traditional serial buses include PCI, CPCI, VME, etc. However, with the increase in circuit design density and the emergence of multi-master control requirements, traditional buses can no longer meet the needs of use and reach a bottleneck. Therefore, a computing pro...
