Partial Reconfigurable FIR Filtering System Using Distributed Arithmetic

Table 5

Reconfiguration time for both DPR system realizations. the 43 kb bitstreamcorresponds to coefficient-only reconfiguration case. The 83 kb bitstream corresponds to full-filter reconfiguration.

Scenario	Reconfiguration speed	Reconfiguration time
		43 KB bitstream	83 KB bitstream
(1) Current	3.28 MB/s	13.10 ms	25.30 ms
(2) Custom [20]	295.4 MB/s	0.145 ms	0.280 ms
(3) Ideal	400 MB/s	0.107 ms	0.207 ms
