请教Keystone 架构POR、Hard reset、soft reset以及local reset区别

Hi,

      看了相关芯片资料,对这几种复位的区别还是模棱两可,能否用简单的语言描述它们的区别。

     另外,对于soft reset和local reset,是否要在DSP要做特殊配置才能生效,因为复位引脚与Hard reset、POR一样?

     谢谢!

 

 

  • POR reset是Power On Reset,整个芯片下电复位;

    Hard Reset和Soft Reset通过管脚或寄存器配置区分,区别在于有些模块在Soft Reset不会被Reset;

    Local Reset只针对DSP的某一个核,需要通过管脚指定某一个核进行Reset。
