I am using Virtex-5 XUPV5-LX110T. I want to implement Distributed Arithmetic and I will use Daubechies 9/7 filters. I want to decompose the LUT, which for computing the high pass coefficients has 9 entries. I want to decompose it in 2 parts to reduce the access time, with 4 and 5 entries. But does this make sense? is there a problem that the two LUTs will not have the same number of entries?
(The same for the low pass coefficients, I want to decompose the LUT with 4 and 3 entries )
