基于AHB总线的DMA控制器的实现与应用

Implementation and application of DMA controller based on AHB bus

通过对AMBA2.0总线结构的介绍以及AHB总线的分析,结合在第三代移动通信终端基带芯片的开发和设计的实际应用,给出了在AHB总线上设计实现DMA控制器的一种方法,并用硬件描述语言(Verilog HDL)实现对DMA控制器的设计,同时用仿真工具进行了仿真分析,并通过可编程逻辑器件(FPGA)完成对设计的验证,形成完整可复用的IP软核,最后该设计成功应用于第三代移动通信终端基带芯片。

Based on introducing the structure of AMBA2. 0 bus and analyzing the AHB bus, a new method which considers the application of the third generation mobile communication terminals base band chip was developed to implement the DMA controller in the AHB bus. The Verilog hardware description language （HDL） was used to design the DMA controller, and the simulation analysis was completed using simulation tool. The designb verification was finished by the programmable logic device （FPGA）, and a complete reusable IP Soft-core was formed. Finally, the design was successfully applied in the third generation mobile communication terminal base band chip.
