Hello,
I am using the function 'getdata' from the Image Acquisition Toolbox in a project. However, the data transfer speed is about 1.5 GB/s. It is my understanding that the data are logged in a Buffer localized on the CPU RAM. Hence, when using 'getadata' to bring the data to the CPU RAM as a variable, the speed should live up to the RAM speed - in my case 21,3 GB/s.
How can I increase this speed?
Any help will be appreciated, please.
Thanks

Hey,
getdata supports multicore.If you have multiple cores you can try using them to increase the speed.
Please refer the following documentation on getdata for further assistance:
Hope this helps!

Great! Could you point toward ressources to dig this matter, and check that this suggestion is working for my issue, please?
Or better, if you could write a bit of code to demonstrate the methodology with 'getdata', I would be very grateful.
Thanks,
Tual
