Wow!!! Thank you for helping me to sort this out!!! Now, I am very happy with the speed I am achieving !!! First thing which had to be done: re-entrants, not only the interp 1d but absolutely all other sub-vi-s. The last trick suggested by Andrey basically almost doubled the speed .....
Now, to finalise my program I have to save the images I am generating. As I am very fast now (around 20 frames per second), saving the images on the hard drive doesn't sound like a good ideea (I'm using IMAQ Write PNG File, image size 512x512). Is there a way to save the images into the RAM (!??!) memory let's say,and "move" them on the hard drive at the end of the aquisition? I'm using a NI1428 board.
Welcome! That was first case where threading "fine tuning" was really useful. Never used these settings before.
If you need to save images more fast that IMAQ Write PNG, then I will suggest to take look into AIPD file format. This is uncompressed format, where you can save every type (even complex), and this really faster than PNG. You will not found this function on the palette. IMAQ WriteFile located here: C:\Program Files\National Instruments\LabVIEW 8.6\vi.lib\vision\Files1.llb\IMAQ WriteFile. Just connect AIPD string to the File Type Input. Otherwise you can create array of the images, then drop this array to the disk after acquisition.
