嵌入式实时通讯控制器设计与实现

Embedded Realtime Communication Controller Design and Implementation

目前系统间通讯问题已经成为制约嵌入式系统性能提高的瓶颈。基于目前嵌入式系统对实时性和系统开销的要求,文章提出了一种嵌入式实时通讯控制器设计,用FPGA实现了同步串行通讯,集成了中断和DMA控制器及双端口存储器,实现了可配置的通讯控制和数据存储功能,并已在某通信产品样机中应用。

In this paper, we present a hardware scheme for Embedded Realtime communication circuit, describe it using VHDL and synthesize it using ISE6.2. The circuit we design contains interrupt control module, DMA module and dual-port RAM. It is configurable and it has been used in a communication product.
