介绍一种利用微控制器动态配置CPLD器件的方法。将配置文件存放在存储器中,配置文件中的控制代码驱动在微处理器中运行的配置引擎;将配置文件中的配置信息通过JTAG口移入CPLD,实现器件的动态配置;通过更换存储器中配置文件,达到同一器件实现不同功能的目的。这种方法为嵌入式系统升级重构提供了一种新的思路,将来一定会得到广泛应用。
Describes a method for dynamically configuring CPLD devices using microcontrollers. The configuration file is stored in the memory, the control code in the configuration file drives the configuration engine running in the microprocessor; the configuration information in the configuration file is moved into the CPLD through the JTAG port to realize the dynamic configuration of the device; the configuration file is changed by replacing the configuration file in the memory , To achieve the same purpose of the device to achieve different functions. This method provides a new idea for the upgrade and reconstruction of embedded systems and will certainly be widely used in the future.
