I attach my program. my program has two loop. I assign to two 2 core of chip. the first loop simulates a moving rectangle. the second loop connect to webcam usb. the webcam captures image. program in second loop process image to determine position of rectangle. the frame rate of webcam is 30 fps. period of processing image is about 33ms. I compare the result from processing image and first loop. I expect processing image delayed 33ms but I receive 100ms. I think problem when grab image. I don't know IMAQ grab.VI, acquired the most new frame. I have two monitor as picture. I have a question, why processing image was delayed 100ms instead of 33ms?
Thank you!
