Heterogeneous Multi-Core SOC Architecture for MPEG Decoding
To deal with nowaday multi-standard audio and video processing,a heterogeneous multi-core SOC architecture is presented in this paper,which is composed of a general purpose RISC processor,an audio processing enhanced DSP and dedicated video processing accelerators. To exploit the task level concurrency among audio-video media decoding,an efficiency and flexible HW/SW cooperating architecture is provided for video decoding,a DSP core is integrated for audio decoding individually,and special mechanisms are designed for inner cores communication and data exchange. The proposed architecture is proto-typed on a FPGA system,which can achieve the MPEG-1/2/4 ASP audio-video real-time decoding in the case of 33MHz system frequency.
