    Correct me if I am wrong but there appears to be the capability of 32 hardware assisted FIR filters each with 1024 taps.
    
 
    Is it possible to build larger filters by cascading these filters together ?? For example if I wanted an 8192 tap FIR filter could I cascade eight of these filters together ??
    
 
    regards

      Hi David,
      
 
      Yes, all the iterations are done in one sample interval one after another and the good thing is that these iterations are taken care by the accelerator automatically. The user have to program the accelerator in the same way whether the number of taps are less than or equal to 1024 or whether it is more than 1024. 
      
 
      Thanks,
