This study explores the idea of building a library of VHDL con gurable components for use in digital radar applications. Con gurable components allows a designer to choose which components he or she needs and con gures those components for a speci c application. By doing this, design time for ASICs and FPGAs is shortened because the components are already designed and tested. This idea is demonstrated with a con gurable dynamic pipelinable fast fourier transform. Many FFT implementations exist, but this implementation is both con gurable and dynamic. Pre-synthesis customization allows the FFT to be tailored to almost any DSP application, and the dynamic property allows the FFT to calculate di erent length FFTs run-time. Three objectives will be accomplished design and characterization of the aforementioned FFT analysis of the error involved in the FFT calculation using di erent twiddle factor bit widths and nally an analysis of all the con gurations for the synthesized design using a 90nm technology library. Speeds of up to 225 MHz have been simulated for a length-1024 FFT using the 90 nm technology.
