摘要
为解决大容量存储设备数据传输速率低、长距离传输的稳定性差以及现有千兆以太网硬核MAC控制器移植性低,可操控性差和在特定结构功能下资源浪费等问题,提出FPGA与物理层芯片相结合方法。通过对MAC层组成结构和工作原理的理解,提出FPGA与物理层芯片相结合方法,来完成数据高速传输。由于使用FPGA实现所以MAC控制器具有可控性强,移植性强,资源用量小和适应性强等特点。在自主研发平台基础上对其验证:表明该MAC控制器具有可行性和可控性。
In order to solve the problems of low data transmission rate of large-capacity storage devices, long-distance transmission stability, low portability of existing gigabit ethernet hard-core MAC controllers, poor maneuverability, and waste of resources under specific structure functions, FPGA and physical layer chip combination method. Through the understanding of the structure and working principle of the MAC layer, a method of combining FPGA and physical layer chip is proposed to complete high-speed data transmission. Due to the FPGA implementation, the MAC controller has the characteristics of strong controllability, strong portability, small resource usage and strong adaptability. It is verified on the basis of a self-developed platform: it shows that the MAC controller is feasible and controllable.
