We need to build an imaging system on 64 bit hardware and Pco Edge camera is connected through their special PCIe card. As this application is a real-time or near real-time imaging system, we would like to know if there is any difference in performance between 32 bit Windows 7 and 64 bit Windows 7 for PCIe communication. As for the camera PCIe card, it has 64 bit driver.
I understand 64 bit OS can handle more memory and little faster than 32 bit one but I searched on web about PCI communication but couldn't find any related material. Any clue or hint would be welcome.
