A rank order filter and instantiation thereof in programmable logic is described. A maximum filter core frequency is determined for an input sampling frequency, a filter window height, and a number of input samples. The maximum filter core frequency is greater than the sampling frequency. The maximum filter core frequency may be insufficient for a word serial instantiation of the rank order filter in the programmable logic. The size of a fully parallel instantiation of the rank order filter may be excessive in programmable logic. Thus, a partially parallel filter core is instantiated for the rank order filter with overclocking.
