Hardware Design And Signal Analysis Of Data Acquisition System Based On DSP

Data acquisition is an important method to gather outside information. With the development of electronic technology, data acquisition technology also has been more widely used. Gradually penetrated into the industrial control, telemetry, remote sensing and other areas of human life.Data acquisition (Data Acquisition), refers to collect the outside world information and process. With the acceleration of electronic devices operating frequency and the increase amount of data collected, the data acquisition system requirements are more stringent. In this paper, we research and design a high-speed data acquisition system based on DSP.The system is based on the structure of DSP and FPGA. System uses high-speed A/D conversion chip to capture the outside information and do the analog-digital conversion, the use of FPGA to complete the system timing control and data caches, the DSP device as the core data processing unit, and finally built through the DSP's PCI bus interface to send data into the PC, for further processing, display and printing.The main contents are:1. The background research in the field of data acquisition, technology development and basic principles are explored and elaborated.2. The data acquisition system design analysis and summary types, and identified the system based on DSP + FPGA integrated design program.3. Complete high-speed data acquisition system hardware system design.4. Analyze signal integrity of the high-speed data acquisition system.
