Design and Implementation of MPEG Audio Layer III Decoder using Graphics Processing Units

摘要：

This paper describes a new implemented method for the MPEG audio layer III (MP3) decoder. The proposed architecture is based on a graphic process unit (GPU)using CUDA environment, where it can effectively take advantage of modern GPUs parallel computing power. The implemented system with this architecture employs a multi-thread, model and memory optimization to process MP3 decoding in parallel, so it is significant to minimize the computational overhead. Experimental results on a GTX260+ graphics card showed that the proposed architecture is over five times faster than traditional MP3 library based on CPU.
