Hi,
I read giant binary files (up to 40Gb) which are films of an industrial process (the total number of images is known). I simply use the Read from Binary File function inside a FOR loop and read it in slices of 76800pixels of 2 bytes each to reshape everything in an array of 320x240. Here is where I use IMAQ Create before IMAQ Array to Image, still inside the FOR loop, to create the array of images that I need.
I avoid memory allocation problems (even if the binary file is huge) by using IMAQ Array to Image inside the for loop, but the VI is "a bit" slow. I did a test for 1GB (around 5000 to 6000 images) and the results are :
-memory (array of images only out of the loop) : 390ko
-time of execution : 20seconds and IMAQ Create represents for a third.
I would like to diminish that time of execution and I thought I could get IMAQ Create out of the loop. Are parallel loops a good option ? And do you see anything else that I could do ?
Thanks for your valuable answers!
PS: I did not post the VI because of the binary file. Screenshot attached
