【摘要】：处理器的计算能力越来越强,各种嵌入式计算平台也是层出不穷。不同平台间的实时通信协议变得多种多样,如RocketIO、PCIe和光纤通道(Fibre Channel,FC)等。为了促进不同系统平台间的高速互连,研究实时数据包重组和多协议传输技术具有非常重要的意义和现实价值。本文主要目标为设计支持PCIe、RocketIO、FC三种通信协议的嵌入式系统,实现PCIe与RocketIO、PCIe与FC协议之间数据包实时重组和传输的功能。本文在深入研究FC、PCIe、RocketIO三种通信协议特征的基础上,提出了针对这三种协议传输的数据格式与转换机制。此外,本文还设计了自定义控制信息数据包,实现了对PCIe转FC、PCIe转RocketIO动态重构和传输协议动态切换。然后,本文在高性能硬件FPGA平台上设计了数据包按地址区分接收模块、DDR存储控制模块、数据流控和组包模块,完成了协议间的数据包重组功能,建立了PCIe协议和RocketIO协议、FC协议和PCIe协议互相转换的通路,并支持FC网络登陆认证和网络管理功能。最后,本文对设计的模块进行了仿真和实测,对数据包实时重组和传输系统的功能和性能进行了验证。最终仿真和测试结果表明:PCIe数据包能够高效的实时重组和通过RocketIO协议发送出去;RocketIO转PCIe速率为240MB/s。PCIe数据包转化成FC帧发送,带宽可达382.34MB/s。PCIe转FC、PCIe转RocketIO两种功能可在自定义控制信息控制下实现动态切换。
[Abstract]:The computing power of processors is becoming stronger and stronger, and various embedded computing platforms are emerging in endlessly. Real time communication protocols between different platforms such as RocketION PCIe and fiber channel fibre Channel (FC) have become diverse. In order to promote the high speed interconnection between different system platforms, it is of great significance and practical value to study the technologies of real-time packet reassembly and multi-protocol transmission. The main goal of this paper is to design an embedded system that supports three kinds of communication protocols of PCIe RocketIOF FC, and realize the function of real time data packet recombination and transmission between PCIe and RocketION PCIe and FC protocol. On the basis of deeply studying the characteristics of three kinds of communication protocols, the data format and conversion mechanism for these three protocols are put forward in this paper. In addition, this paper also designs the self-defined control information packet, realizes the dynamic reconfiguration of PCIe to FCU PCIe to RocketIO and the dynamic switching of transmission protocol. Then, this paper designs DDR storage control module, data flow control module and packet formation module on high performance FPGA platform. The PCIe protocol and RocketIO protocol, FC protocol and PCIe protocol conversion path are established, and FC network login authentication and network management functions are supported. Finally, the module is simulated and measured, and the function and performance of the real time data packet recombination and transmission system are verified. The final simulation and test results show that the 1: PCIe packet can be efficiently reorganized in real time and sent out through RocketIO protocol. The rate of RocketIO to PCIe is 240MB / s. PCIe data packet is converted into FC frame transmission. The bandwidth can reach 382.34MB / s. PCIe to FCU PCIe to RocketIO can be dynamically switched under the control of custom control information.
