Layout Aware Optimization of High Speed Fixed Coefficient FIR Filters for FPGAs
Figure 14
Resource utilization and performance implementation results for various filters using add and shift method (this paper) relative to that of SPIRAL automatic software. SPIRAL shows a saving of 72% in FFs, 11% in LUTs, and 59% in slices at the cost of 68% drop in performance. (a) Resource utilization in terms of # of FFs, LUTs, and SLICEs. (b) Performance (Msps).
