Problems solved by technology

Especially in the storage system with high-speed backplane interconnection, many storage interfaces need to be connected, but the resources of the existing system are insufficient, and the interface needs to be expanded. The expansion of the high-speed bus interface of the existing aurora protocol is insufficient

Abstract

The invention discloses a high speed bus interface expansion structure based on the aurora protocol. The high speed bus interface expansion structure based on the aurora protocol comprises a host_aurora (host computer terminal aurora interface) module, a host_user_app (host computer terminal user application interface) module, an exp_aurora (expansion board terminal aurora interface) module and an exp_user_app ( expansion board terminal user application terminal) module.The high speed bus interface expansion structure based on the aurora protocol ensures stable transmission of high speed data and achieves highly-efficient, flexible and convenient expansion of the storage interface through customization of a proprietary protocol which achieves expansion of a storage interface through a high-speed bus light weight interface function of the aurora protocol.

Description

technical field [0001] The invention relates to the field of bus interface and storage technology of a computer system, in particular to an extended architecture of a high-speed bus interface based on the aurora protocol. Background technique [0002] Aurora protocol is an open and free link layer protocol provided by Xilinx, which can be used for point-to-point serial data transmission, and has the characteristics of efficient data transmission and ease of use. Aurora is a relatively simple protocol, controlling only the link and physical layers. Aurora's design philosophy is to enable other high-level protocols, such as TCP / IP and Ethernet, to easily run on top of Aurora. The Aurora protocol uses one or more high-speed serial channels to form a higher-speed channel. The RocketIO hard core is encapsulated inside Aurora, allowing devices to communicate through multiple GTX channel bonding in the backplane. A single GTX channel can realize communication transmission of 750M...
