With the development of the information technology, single digital signal processor (DSP) cannot meet the requirements of massive data processing. Multi-DSP parallel processing mode has been commonly used in real-time information processing system. New technology is also making it much easier to integrate multiple DSPs into a single silicon chip.  However, designers of a new multi-DSP system and software are confronted with problems such as short product life-time. Meanwhile, product verification is indispensable before launching into the market. In this paper, a multi-DSP simulation platform is developed to solve these problems. The designed multi-DSP platform is based on an ISS-SystemC structure and has three common interconnect interfaces. An AMBA bus-shared memory model is designed for the expansion of the simulation system. A thread-agent method is proposed to optimize the performance of SystemC thread and the experiment results show that the multi-DSP parallel processing mode can improve the processing performance of the system significantly.
