Design and implementation of EPA communication scheduling based on FPGA

通过分析EPA通信调度原理,提出一种采用硬件方式实现确定性通信调度的方法,避免了EPA通信调度算法受CPU中断和操作系统等因素的影响,并设计出基于FPGA的EPA通信调度系统。本文着重对EPA通信调度功能模块以及通信调度控制算法进行设计,形成了EPA通信调度算法的IP核。并编写testbanch测试文件,通过建立实验验证模型,对该IP核进行逻辑功能验证。测试结果证明了该系统能够实现EPA通信调度算法的调度功能。

In this paper,analyzing the EPA Communication Scheduling theory,propose a method that can be achieved by hardware for communication scheduling function,avoid the interruption of CPU and operating system and other factors,and design the method of EPA communications scheduling system based on FPGA.This paper focuses on design the EPA communication scheduling function module and communication scheduling control algorithm,and formed the EPA communication scheduling algorithm for IP core.And write testbanch test file,through the establishment of experimental verification model,the logic function verification of the IP core.Test results prove that the system can achieve scheduling capabilities of the EPA communication scheduling algorithm.
