Partial Reconfigurable FIR Filtering System Using Distributed Arithmetic

Table 1

Fir filter implementation savings due to the use of filter blocks.

Implementation	Resource requirements
1 Filter block of size 𝑀 (LUTs have 𝑀 inputs)	size𝐼×2^𝑀 words
𝑀/𝐿 filter blocks of size 𝐿 (LUTs have 𝐿 inputs)	size𝐼×2^𝐿×𝑀/𝐿 words
