摘　　要：基于IP核的设计方法,设计一种基于AMBA总线的EPA片上通信系统。系统以EPA通信IP核为核心,该IP不仅实现了通信调度、时钟同步等EPA的核心机制,同时实现EPA的动态组态、即插即用、支持普通以太网收发等功能。EPA通信IP核与片上CPU的软硬件协同工作,结合片上FLASH、片上SRAM以及GPIO等,形成为一款SOC芯片,不仅提高了EPA通信的实时性和灵活性,更使得EPA通信系统具有更高的集成度、安全性以及更广阔的市场。Based on IP core design method, designed an EPA on-chip communication system with AMBA bus. The system is centered with EPA contribute core. The core not only realize communication scheduling, clock synchronization and other EPA core aspects, but also realize EPA dynamic configuration, plug and play, support normal Ethernet IO functions. EPA communication core works with the software and hardware of on-chip CPU, integrated with on-chip Flash, on-chip SRAM, GPIO and other blocks to be one SOC chip. It enhances the instantaneity andflexibility of EPA communication in order to let the EPA communication system has better integration, safety and broader market.
