FIR Accelerator window size more than 1024

Dear Team,

       I would like to perform FIR accelerator with 8192 Taps & window size with 2048.

For Taps size more than 4096 , I understand that Taps can be split into two times but how to handle window size more than 1024 in FIR accelerator?

Regards,
