摘要
在无人值守的网络实验环境下,传统DSP实验程序的下载方法无法解决程序代码的远程下载问题。结合网络实验室的特点,应用串行引导加载技术,将用户程序通过串口远程加载至DSP片外RAM。这种方法降低了硬件成本和开发难度,提高了实验系统的性能。给出了Netlab DSP实验系统的框架、串行引导加载的硬件电路和软件实现,为远程监控、网络实验及设备远程升级等应用提供了一种有效的设计思路。
Under the unmanned experimental environment of Netlab, several conventional methods are incapable of remotely loading user＇s code. According to the requirement of DSP Netlab system, a serial bootloader technology was introduced, which can remotely load the user＇s code into DSP＇s external RAM through the serial port. It consequently reduces the cost of hardware, simplifies the system development and improves the performance. The framework of DSP Netlab system, and the hardware circuit and software implementation for serial bootloader were described, providing an effective method for design and development of remotely monitoring, experimenting and facility updating.
