Embodiment Construction

[0051] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, and therefore are only examples, and cannot be used to limit the protection scope of the present invention.

[0052] figure 1 Shown is the realization flowchart of the data processing method based on the server multiprocessor board device provided by the present invention, which specifically includes the following steps:

[0053] In step S101, the bus controller uses the address signal of the board device to periodically poll the slave devices mounted on the bus sequentially, and judge whether there is a data read and write request from the board device mounted on the bus.

[0054] In step S102, when it is determined that the board device mounted on the bus has a data read / write request, the bus controller controls ...

Abstract

The invention relates to the technical field of multi-processor systems. The invention provides a data processing method between board card devices based on a server multiprocessor, and the method comprises the steps: enabling a bus controller to sequentially carry out the timing polling of slave devices mounted on a bus through a board card device address signal, and judging and detecting whetherthe board card device mounted on the bus has a data read-write request or not; when it is judged that the board card device mounted on the bus has a data read-write request, using the bus controllerfor controlling and distributing bus control power, controlling commands between board cards and reading and writing of data, and providing a high-performance bus structure which is good in expansibility, convenient for increasing and decreasing nodes and good in system elasticity, and the data are directly transmitted on equipment, so that time delay and bandwidth are guaranteed, and fewer resources are occupied.

Description

technical field [0001] The invention belongs to the technical field of multiprocessor systems, and in particular relates to a data processing method based on server multiprocessor board devices. Background technique [0002] Distributed multiprocessor system is an important architecture in the field of high-performance servers, and how to communicate easily and efficiently between multiprocessor boards is an important content of research. [0003] At present, the mainstream high-efficiency communication methods between multiprocessor boards include crossbar switch, bus, PCIe, and MAC, etc., but these efficient communication methods have more or less defects: [0004] The performance of the crossbar switch is high, but due to the limitation of the expansion of the crossbar switch due to chip pin resources and large-scale logic resource overhead, its expansion capability is insufficient; [0005] Currently, there are switching chips that support the PCIe interface on the mark...
