Abstract


With the rapid development of FPGA technology, advantages of FPGA in the signal acquisition and processing are increasingly evident. FPGA chip, not only has a very strong logic control, but also has a strong digital signal processing capability. Now a new type of FPGA generally are integrated DSP blocks, and even embedded in the soft/hard-core processor, coupled with FPGA parallel processing in the signal strengths, allowing FPGA-based signal acquisition control and signal processing is completely possible.In this paper, signal acquisition and processing technology based on FPGA is researched. FPGA is the core of the signal acquisition and processing systems, it controlled each module to complete signal acquisition and processing tasks. The article mainly researched and designed of FPGA-based control and processing systems, including FPGA-based signal acquisition module, FPGA-based signal processing module and FPGA-based storage control module. Acquisition and control module is mainly for controlling channel selection switch and A/D converter to work that generate multi-channel selection logic control signals and A/D conversion timing control in order to complete the multi-channel analog input signal acquisition control; Signal Processing Module mainly for through the A/D converted digital signal to FFT processing; storage control module’s role is to control the memory work, that is, memory logic control signals generated, in order to achieve control of the processing results of store.Signal acquisition control and processing system based on FPGA has a short development cycle, design flexibility, low cost and high reliability, so FPGA is the ideal framework of signal acquisition and processing. Signal acquisition and processing technology based on FPGA has a very wide range of applications prospects.
