Research on Embedded Data Acquisition and Processing Based on ARM

摘要

With the rapid development of the computer computing, the embedded system has been widely used in industrial control, home appliances, mobile communications and other industries. This paper mainly studies the data acquisition and processing of embedded data. First, it introduces theintegrated development environment of ARM, and analyzes the operation process of LINUX on ARM. Then, it studies the data processing of the embedded system based on the principles of embedded system and presents the butterfly algorithm according to discrete Fourier transform (DFT) Principle,which is realized on the basis of S3C2410X microprocessor. Finally, the decimation-in-time radix-2 FFT computation block diagram is established, which lays a foundation for the future programming.
