基于SOPC的音频终端设计

音频终端基于FPGA外围电路设计和Nios Ⅱ系统设计。其中,Nios Ⅱ片上系统由Nios Ⅱ软核、以太网芯片控制器、CFI(Common Flash Interface,公共闪存接口)控制器、SDRAM控制器等IP构成,并详细介绍了各个IP的原理和设计说明。在设计中,用Altera公司的Quartus Ⅱ软件完成了所有的工作。设计的IP网络广播终端在PC和FPGA/SOPC开发平台上得到了验证,实验结果表明,设计的IP网络广播系统基本达到了预期目标,对实用化的IP网络广播系统开发具有一定的参考价值。

This paper introduces the principle and design each IP description.In the design,Using Altera company＇s QuartusⅡ software finished all the work.This IP network broadcasting terminal designed in this paper is verified in PC and FPGA/SOPC development platform,experimental results show that the design of the IP network broadcasting system basic goal,is expected to reach the IP network broadcasting to practical systems development to have the certain reference value.
