LogiCORE Fast Fourier Transform (FFT) v6.0 - When I target a Radix-4 implementation, the resource count in the GUI is more than what I see in the MAP report. Why?

説明

When I target a Radix-4 implementation, the resource count in the GUI is more than what I see in the MAP report. Why?

ソリューション

There is a problem with the resource estimation, when targeting a Radix-4 implemenation, where the resource estimation can be off by a factor of 2. (i.e. , The GUI might say 104 DSPs, but the final implemenation is only 54.) 

 

To find the correct resource usage, see the MAP report.
