Software Design Based on PLD High-Speed Data Acquisition System

Abstract

Data collection in the important position of modern industrial production and scientific research is increasingly outstanding, as well as the real-time collection, real-time transmission and real-time processing of high speed data acquisition requirements are constantly improve. In addition, for different occasions, the data acquisition system of data sampling parameters are different. PLD as a universal integrated circuit, its logic function according to user's programming on the device, this paper introduces the high-speed data acquisition system based on PLD, mainly expounds the software design of the system, this paper introduces a simple PLD system, using FPGA as the data acquisition chip, the main measure the infrared remote control code acquisition, based on EDA technology to design a core, using DMA access to data, to achieve high-speed system requirements.
