With the growth in high performance multimedia applications, specialized hardware for certain tasks is desirable. While ASICs provide a solution addressing performance, they are unable to provide an optimal solution for a given problem instance. FPGAs can be used with run-time reconfiguration to dynamically customize a circuit. Optimizations leading to faster circuits and reduced logic can result. The paper discusses the implementation of a run-time parameterizable 2D Discrete Wavelet Transform core using the JBits tool suite. The motivation for such a core is discussed, as well the benefits afforded by dynamic circuit specialization.
