Abstract :
Based on the reference model of the multiplication removal quick second-order low-pass filter and state machine implementation through timing sequence instruction, the paper proposes the designing method of the state machine for multi-frequency point IIR low-pass digital filter. Thus, it sets to meet the requirements of multi-frequency and quick filtering in the digital digital processing system. It then verifies the correctness and feasibility of the functions of filter state machine through ModelSim simulation. At last, it optimizes the performance of quick second-order low-pass filter through cascading method and realizes sound application in the silicon micro-machined gyroscope digital measurement and control system.
