基于TMS320F2812的红外信息处理硬件平台设计
|
摘要
在红外信息处理系统中,硬件平台的设计是非常重要和关键的工作。介绍了一种基于TMS320F2812的红外信息处理硬件平台的设计方法,该平台有10路A/D采样通道,具备自动增益调节电路和多路D/A转换电路。讲述了TMS320F2812的性能和工作原理,及其外围接口电路和底层软件的设计。最后对该平台进行了相关实验,实验表明,该平台满足了系统处理速度更快、系统功能便于扩充的要求,具有较好的稳定性和可靠性。
The design of hardware platform are very important for processing infrared information.The paper introduces a designing method of infrared information processing hardware platform which is based on TMS320F2812.The platform has ten sampling channels,automatic gain control circuit and kinds of D/A conversion circuit.This paper discusses the capability and elements of TMS320F2812,and gives the designing of peripheral and external interface circuits,and the designing of driving program.The last give the experiments of the platform.The results of the experiment show that the platform can satisfy the requirement of system.The platform has good stabilization and dependability.
