摘要
提出了一种嵌入式音频解决方案,该方案基于AC-link协议,数字逻辑采用Verilog HDL设计,支持多通道存储器直接存取(Direct Memory Access,DMA)传送,驱动程序采用了双缓冲机制.对系统方案进行了分析,介绍了主要硬件模块的实现方法和驱动程序的设计思路,在此基础上以43万等效门实现了整个设计并通过验证.
An embedded audio solution based on AC-link protocol that supports multi-channel （Direct Memory Access, DMA） transfer and dual-buffer mechanism is presented in this article. System solution is analyzed and the realization method of main hardware modules and software driver is introduced. The digital logic units of the audio system are designed by Verilog HDL and the whole design is realized and verified by 430 000 equivalent gates.
