Are the Buffers Allocated in an IMAQ Buffer List Contiguous in Memory? Primary Software: Driver Software>>NI-IMAQPrimary Software Version: N/A Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I would like to know if the image buffers that are allocated in a buffer list using the NI-IMAQ driver are adjacent to each other in memory, or if there are gaps between the buffers. Solution: Buffer allocations are actually managed entirely by the operating system. Although it is guaranteed that a single buffer will have a contiguous block of memory, it is unknown where corresponding buffers will be located in memory. However, the relative location of these buffers in the buffer list has no performance impact on accessing the images because solid state RAM can access any physical address within the same amount of time.
