摘　　要：提出了一种基于CKCore RISC处理器和Spock DSP处理器的异构双核系统芯片平台(GEM-SoC)。该平台通过提供可配的功能IP模块和灵活完善的软硬件架构,使得异构双核SoC设计更为准确高效。实验证明,GEM-SoC平台可以有效地加快Ogg解码应用的双核软件程序设计开发。原型芯片在37.68 MHz时钟频率时运行,即可实现实时Ogg音频解码播放,具有较好的功耗性能比。The paper presents a new heterogeneous dual-core GEM-SoC platform based on CKCore RISC processor and Spock DSP processor. This platform is able to provide eonfigurable functional IP and flexible software/hardware architecture to improve the efficiency of heterogeneous dual-core SoC design. The experiment shows that the GEM-SoC platform can efficiently speed up the development of dual-core software programs for Ogg audio decoder. The prototype chip of GEM-SoC can fulfill real-time Ogg decoding at 37.68 MHz clock frequency so as to obtain good tradeoff between performance and power.
