Abstract
A programmable hardware architecture and design methodology for the implementation of a sample rate conversion engine is presented. The conversion engine supports scalable filter taps and can be tuned to a range of interpolation and decimation requirements. The conversion engine can be used effectively in wideband systems to efficiently extract and process digital sequences with protocol specific sampling rate requirements. The conversion engine can also be used as a hardware accelerator for software defined radios and communication systems that require adaptive sampling rates.
