An adaptive filter is a filter that can adapt the given environment through self-learning process using optimization algorithm by adjusting the filter co-efficient of the input signal. Adaptive filter is the very essence for today’s different application such as Echo Cancellation, Noise Cancellation, System Identification and so on. In this paper we present the design and implementation of acoustic echo cancellation using the art of Xilinx Zynq platform Zed board and by applying a model-based design approach for hardware software co-simulation in Simulink. From the original signal echo generating model is designed for multiple path delay. The echo version of the original signal will be removed by using LMS adaptive filter algorithm which is a simple and robust in performance. RTL (Register Transfer Level) design is generated from the subsystem of echo cancellation design model by converting to intellectual property (IP) core for FPGA implementation using HDL workflow advisor in Matlab Simulink, finally the custom board reference design from Vivado will apply for real time audio output test that integrated with the model design. The hardware software cosimulation shows that the proposed FPGA implementation has cancelled the echo with high performance.
