Realtime replacement mechanism of internal and external memory in limited resources system applicating 5G communication module in distributed grid terminal

System level software need read and write hardware memory, and some hardware system with limited resources such as 5G communication terminal in distributed grid application could not provide enough memory space for specified system application minimum demand. Some current method such as hardware expansion or software compression, to some extent, take effect, but could not solve the problem. Base on contrast between internal and external memory and single task independence, this article propose a realtime replacement mechanism to face on the situation and solve the problem met in high speeding data transfer distribute gird function as usual between running memory and limited resources. Experiment show that it could support limited resources system to run memory-needing task, and running efficiency is 90.2% about to hardware expansion.
