【摘要】 提出一种嵌入式DSP系统的存储优化方法 该方法利用遗传算法求得存储需求量较少的同步数据流 (Syn chronousDataFlow ,SDF)图顶点调度序列 ;使用TPFIFO(Two PortFIFO)数据缓冲模型来实现顶点输入边和输出边的存储共享 ,以进一步提高数据缓冲的利用率 实验结果证实了该方法的有效性更多还原

【Abstract】 An approach for reducing memory requirementf of embedded DSP systems is presented Such an approach is based on a genetic algorithm to efficiently explore the exponential search space of actor firing orders A two-port FIFO buffer model is applied to improve the buffer utilization by allowing two simultaneous accesses to the same buffer Experimental results prove the significance of the proposed approach更多还原
