Soft real-time scheduling of the hardware tasks is one of the key factors which affect the performance of dynamic reconfigurable systems.This paper presents a scheduling algorithm MSSA(minimun space scheduling algorithm) based on the minimum space between the hardware tasks of the vertex list.The algorithm constitutes a three-dimensional resources model according to the length,width and the activation time to reach the adjacent degree of the task and the task placed in the three-dimensional space to construct the cost function,which obtains t...
