Design and Implementation of Embedded Data Acquisition and Processing System Based on DSP Technology[HS)]

摘要:

为了解决数据采集速度慢以及任务量大等问题,提出了一种基于DSP技术的嵌入式数据采集与处理系统方案；方案充分利用了DSP技术的运算能力强优点,从而实现了系统的快速运算以及有效控制;文章主要以系统的硬件设计和软件设计来对系统进行详细设计；在系统硬件设计部分,根据系统的需求以及DSP芯片的选型原则,系统选用了TI公司的32位定点DSP芯片—TMS320F2812,参数按照标准设置,并确定系统的总体设计方法,完成了控制 AD芯片的采集模块设计；在系统软件设计部分,主要是对外扩芯片的控制,其中包括了控制 AD采集时序以及DSP读写数据程序等。

Abstract:

In order to solve the problem of video monitoring system in the data acquisition speed is slow and heavy task of problem, put forward a scheme of embedded data acquisition and processing system based on DSP technology. Scheme makes full use of the powerful calculation of the advantage of DSP technology, to realize fast operation system and effective control. In this thesis, the hardware design and software design are oriented to complete detailed design of the system. In the hardware design part, according to the principle of selection of system requirements and DSP chip, the system chooses the TI 32 bit fixed point DSP chip TMS320F2812, and the method for determining the overall design of the system, completed the design of data acquisition module to control AD chip; in the system software design part, mainly is to control the external expansion of the chip, which including the control of AD and DSP to read and write data acquisition timing program etc..
