摘要

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.
