Hello Ashwin,

The CIC and FIR compilers support configurable rate change in sysgen.

Re: dynamicallty configurable resampler

Thanks for your reply.

I checked CIC filter, it has the option of dynamically configuring rate change... BUt not FIR compiler..

But CIC does not meet performance characteristics, so i am looking for anyway with which i can use FIR compiler with on-fly rate change option.

Sorry about that; I was mistaken about the FIR.
