摘要:
文中研究了一种基于傅立叶变换和Nios软核控制器的硬件音频信号分析方法,并构成一种音频信号分析仪。该仪器通过Avalon—ST总线有效的把FFT IP核与Nios软核处理器有机的结合起来,在FPGA芯片上配置NiosⅡ软核处理器和相关的接口模块来实现嵌入式系统的主要硬件结构,该结构使得软件和硬件集成到一片可编程逻辑器件平台上,使设计同时获得软件的灵活性以及硬件的高性能优势。设计中,在AlteraEP2C35系列FPGA芯片中嵌入NiosⅡ软核处理器,使之集成在一片FPGA上,开发效率高、灵活性强,能较好地满足的市场需求
Abstract:
A technique for realizing audio signal analyzer based on the NioslI that utilizes NiosU soft-core processor to achieve the real-time measurement and analysis is presented. The FFT IP core and NioslI soft-core processors are combined effectively through the Avalon-ST bus in the instrument. By configuring NiosⅡ soft-core and interface module on the FPGA chip the main hardware structure of the embedded system is constructed. Software and hardware are integrated into a single programmable logic device platform, therefore the instrument has advantages in flexibility and high-performance both. In the design, Altera EP2C35 series FPGA chip is chosen and embed- ded with the NioslI soft-core processor. The instrument is able to better meet market demand with its efficiency and flexibility
