MC43 RAM Utilized

ksilovich 4 years ago in IQANdesign updated by Gustav Widén (System support) 4 years ago 1

We just wrote our first program an MC43 and it is taking up 1.4 of the 1.5MB.  

I thought the days of watching RAM utilization was gone after the MD4 came out.

Our last 2 programs utilized the MD4 as the master.  


Will IQAN 5 help with decreasing RAM utilization or what is the best practice to try to reduce it in this program?

If an application is just updated from version 4 to IQANdesign 5, it will use up almost the exact amount of RAM. 

(I just did a small test myself, and saw on 6KB difference on an almost maxed out IQAN-MC43 application)


What IQANdesign 5 could possible help with is to structure the handling of machine variants differently. 


It is very hard to say anything about general about how to optimize the memory utilization of an application, but the starting point should always be to look at which function groups it is in the statistics that takes up most of the memory.
