The FIR IP takes arrays as arguments. It has a parameter that specifies the length of those arrays.
I am wondering if it is possible to run this function sample by sample? That would be something like the fir function
in the first chapter (Introduction) of the HLS tutorial. In that example there is a static array which preserves the content
of the delay line between function calls. The reason I want to run the FIR IP in this mode is because I want to add a function after it
that works on individual samples. It would be unnatural to take a whole array from the FIR.
