Abstract: In this work, a new run-time reconfiguration multi-DSP system architecture was given. In this system, combining the characteristic of the multi-processor parallel computation and worm arithmetic, a mixed architecture that can be adaptively expanded based on shared bus and linkports was constructed. And the system was designed and discussed from the point of measurability. Self-Adaptive operating system, a feasible project was proposed for the high speed Self-Adaptive signal processing platform. The hardware debugging, system testing and the software loading methods were introduced. These works may offer some meaningful reference and guide for some similar systems developed in the future.
