A General Software Design for High-speed Bandwidth Data Communication in VPX Architecture

在高速带宽数据通信系统中,同时存在多处理器的应用环境下,网控器需要完成复杂的多路协议切换以及对无线网络进行实时管理,数据传输量大,硬件接口十分复杂。文章提出一种基于VPX架构的高速带宽数据通信平台的通用软件设计,VPX总线可以为PCIe,RapidIO以及万兆以太网等高速总线提供更高的背板带宽。该通用的软件设计,屏蔽了IO物理接口的区别,方便移植,同时也能够满足实时数据通信中大计算量、大数据量以及高带宽传输的需求。

In a multi-processor communication system which has high-speed bandwidth,the network controller needs to complete the complex multi-link protocol conversion and real-time management of the wireless network where the volume of data transmission is large and the hardware interface is very complex.This paper proposes a general software design for the high-speed bandwidth data communication platform based on VPX architecture.The VPX bus supports higher backplane bandwidth for high-speed buses such as PCIe,RapidIO and 10-gigabit Ethernet.The general software design not only shields the difference of IO physical interface,which is convenient for transplantation,but also meets the requirements of large computation amount,large data volume and high bandwidth transmission in real-time data communication.
