Is NI GigE Driver compatible with either (a) Mobile Intel HM77 Express Chipset or (b) Mobile Intel QM77 Express Chipset?

[larry2]

NI high seed Image Acquisition From GigE Vision Cameras uses NI Driver software that is compatible certain hardware, i.e.. like NI PCIe-8231 (1-port PCI Express board) that uses Intel 82572EI Ethernet interface chip. i have a desktop system using such stuff that works excellent. i would like to use a notebook. Dell says that their notebooks have either (a) Mobile Intel HM77 Express Chipset or (b) Mobile Intel QM77 Express Chipset. Is the NI Drive compatible with either of those chipsets? thanks for your time and efforts.

I am not sure about these chips but you can actually use imaqdx through a regular Gigabit driver assuming the chip supports jumbo packets (not all chips work but some do).  The NI driver is preferable since it is optomized and offloads some if the work to the chipset instead of the CPU (not as important as it used to be because the cpu are so fast).  There is a chance that you can still get the camera to work correctly even if NI driver is not supported.  What camera are you using?

i believe the camera is a Basler acA640-100gm. operating at 640x240, 380 fps. on an I7 desktop PC. Labview running 2 parallel vi's. one with 24/7 video input, compression, storage (my compression algorithm). second vi is doing particle id... Matlab is running in parallel (time delayed) and tracking particles, computing particle velocity, and computing\displaying\storing size distributions.

i understand that the camera will likely work with other ethernet hardware, however i'd like to use the NI-driver to ensure max image thru put... i think the NI driver does some packet stuff that reduces per image packets from 3 to maybe one... and thus the speed enhancement.

you comments are certainly appreciated.

Compares the Universal to High performance driver,

specifically both provide the same max bandwidth of 125MB but the high performance driver takes advantage of the intel pro1000 chipset to offload some of the CPU load, again this is less important as processors become faster.

"Advantages
While the high performance driver provides better CPU performance compared to the universal driver, it will only work on Gigabit Ethernet cards with the Intel Pro 1000 chipset. The universal driver can work on any Gigabit Ethernet card recognized by the Operating System. CPU usage during acquisition will affect the CPU cycles available for image analysis. So if your application requires in-line processing, it is better to invest in a Gigabit Ethernet card with the Intel Pro 1000 chipset like the NI PCIe-8231. While your choice of driver affects the CPU usage, it does not limit the maximum bandwidth possible. Either driver will be able to achieve the maximum bandwidth of 125 MB/s."
