本文对一种基于FPGA和软核CPU的嵌入式系统设计的方法进行了描述,整个系统以FPGA和NIOS为中心进行设计,外围接口包括JTAG、串口、USB口等。系统选用ALTERA公司的Cyclone系列的芯片作为核心处理芯片,配合ALTERA公司推出的NIOS软核嵌入式处理器构成整个系统的核心。操作系统采用μC/OS嵌入式系统,并移植到FPGA平台上。
This paper describes an FPGA-based and soft-core CPU-based embedded system design approach described, the entire system FPGA and NIOS as the center of the design, peripheral interfaces include JTAG, serial port, USB port. System uses ALTERA’s Cyclone series of chips as the core processor chip, with the introduction of ALTERA NIOS soft-core embedded processors form the core of the entire system. Operating system using μC / OS embedded system, and ported to the FPGA platform.
