| Abstract: | This paper proposes a method for Controllable Digital Filter design.Taking the FIR as an example,we implement a digital filter with variable spectral characteristics by customizing embedded MPU,constructing FIR with confirmable-coeffs and other modules.The design examples,based on Modelsim post-routed simulation and onboard running on XUPV5-LX110T,are provided to demonstrate the effectiveness of the proposed method and the online-adapability of digital filters. |

| Keywords: | controllable digital filter field programmable gate array embedded MPU Configurable FIR Filter |
