摘要
随着通信系统对信号处理的要求不断提高,传统芯片难以满足高速处理的要求。FPGA以并行处理能力强、集成度高、可系统重构等特点得到了广泛应用。本文设计了以高性能FPGA为核心,具有嵌入式ARM的SOC功能,结合CPLD、DSP、ADC等技术,组合SDRAM、FLSAH存储器等外围电路构建一款中频数字信号处理和数据处理平台。经工程实践验证,系统设计可靠、运行稳定。
With the development of communication system,the requirement of signal processing is improved,traditional chip has been difficult to meet the requirements of high-speed processing.FPGA is widely used in parallel processing capability,high integration,reconfigurable system etc.This paper design the SOC function with embedded ARM based on high performance FPGA,combined with CPLD,DSP,ADC technology,including SDRAM,FLASH memory and other peripheral circuits,constructed an intermediate frequency digital signal processing platform.Through engineering practice,the system design is reliable and the operation is stable.
