Abstract: In order to improve MP3s’ decoding speed,the IMDCT algorithm is decomposed and a NiosII soft-core-based IMDCT algorithm hardware structure is designed as a hardware accelerator module on the SOPC system for decoding. Experiments show the operation speed of the hardware accelerator is about 4.4 times that of software operation.
