Any way to save data in loop without using shift register or feedback loop

[tombech]

Hello all

I was thinking, is it possible to save data in a loop to next iteration without the use of a shift register or a feedback loop?

I need the possibility to reload data within a loop from a lvm file, but I want to use the same data until i load some new ones.

The reason why I don't want to use the shift register or feedback node is due to speed, even though I am not sure if the shift register

actually moves all the data from one register to another, or if it is stationary until a change in the data occur.

The data I want to reuse is medium-large (6 force measurements, 2 pressure, 1 flow channels)of about 10sec data in each file with samplingsrate of 2kHz..

In my analysis program I have many CPU demanding calculations and 3D graphs, so I just want to minimize the CPU load as much as I can for each part of the

software..

I have attached a small VI to explain what I am talking about.

I now I shouldn't use the express VI, and I am going to change that as well - this is just a proof of concept! 

Hope you guys can help me understand this shift register better...

Thanks!

If speed is the name of the game, go with the (data)flow and stick to shift registers or the feedback node.  No data is moved around, their job is to do pretty much exactly what you are describing.  Any other solution, controls/locals/globals will involve copying data and then you will have problems with speed.

 Tommy,

shift register are the fastest you can ever get...........
