基于ADSP-21369的浮点DSP实验教学系统设计

摘要

This paper focused on the research and design of Floating-point DSP Experimental Teaching System based on ADSP-21369. It was implemented the control of SDRAM, FLASH, ADC, DDS and other external memory by ADSP-21369 and other analog devices. LCD, UART and keyboard could be controlled by using ADSP-21369's inherent resources and the digital peripheral interface (DPI). The digital application interface (DAI) could be used to control the audio, S/PDIF and LED.%本文研究并设计出一套基于ADSP-21369的浮点DSP教学实验系统.采用ADSP-21369处理器,辅以其它模拟器件,实现对SDRAM,FLASH,ADC和DDS等外部存储器的控制.利用ADSP-21369的固有资源,通过数字外设接口(DPI)完成对LCD,UART及键盘控制,通过数字应用接口(DAI)完成对音频,S/PDIF和LED灯等的控制.
