 note = {This paper presents an implementation of a stereophonic acoustic echo canceller on nVIDIA GeForce graphics processor and CUDA software development environment. For ef.ciency, fast shared memory has been used as much as possilbe. A tree adder is introduced to reduce the cost for summing thread outputs up. The performance evaluation results suggest that Even a low-cost GPU's with a small number of shader processor greatly helps the echo cancellation for low-cost PC-based teleconferencing. ©2009 IEEE.., 金沢大学理工研究域電子情報学系},
