Right now I have a .NET object that I use to read data from some hardware. I also need to process that data in real time so I can perform other operations. I currently have the data acquisition take place in a timer callback and the processing take place in a while loop (both processes access the data from the same workspace).

However, this is not good enough for a real time system. I can sometimes see delays of up to 380ms since the data cannot be processed while the program is in the callback. So I have been looking into parallel processing (with parallel computing toolbox) to speed the process up. But, as you could imagine, I am having great difficulty doing so.

Is it possible for me to create too workers, one with the .NET object that does all of the data acquisition, and another that does all of the processing at the same time? If so, how should I go about this? Or if there is a different approach that I am not aware of? I would deeply appreciate any help that someone can offer.

Hi Evan,

Looks like there is some missing information in the 1st paragraph.

Also, not sure if it is related to your use case, but here is doc that can be a good start:

My appologies for the late response, I actually have seen this doc before. However I am still confused on how to acutally make the different workers perform the two functions I spoke of before
