基于MicroBlaze软核处理器的Bootloader设计

文章介绍了基于MicroBlaze软核处理器的Bootloader程序的设计,详细介绍了适用该程序的FPGA嵌入式系统的硬件配置及Bootloader程序设计的硬件逻辑设计流程和软件设计流程。该程序是在FPGA硬件配置完毕之后,在内部处理器上运行的一段启动代码,用来将FLASH中的用户程序传输至外部RAM,并引导嵌入式系统从用户程序中开始运行。它解决了使用大规模复杂应用程序的嵌入式系统的引导问题,已在实际中应用,具有良好的适应性。

Design of Bootloader Based on MicroBlaze Soft Core Processor

The paper introduced a design of Bootloader program based on MicroBlaze soft core processor,and described hardware configuration of the FPGA embedded system which is suitable for Bootloader program and flow of hardware logic design and software design of the program.The Bootloader program is a set of start-up codes which runs in the internal processor after hardware configuration of the FPGA is completed.It is used to transmit user's application program from FLASH to external RAM and boot the embedded system.It solved the boot problem of embedded system with large complicated applications.It has applied in practice and has better adaptability.
