After analyzing the characteristic of the parallel processing system, some problems about design missile - carrying processing system are pointed out ; network in the parallel processing system has become bottleneck and affect the performance of system, so the processing efficiency is analyzed in a multiprocessor system based on cluster - bus and some rules in designing the network in the multiprocessor system are brought out ; genetic algorithm is used for scheduling in the multiprocessor system, and a scheduling algorithm is described to suit arbitrary number of tasks, unequal task processing time, arbitrary precedence relation among tasks and arbitrary number of parallel processor, so that the schedule length will be minimized ; finally, an atr algorithm is mapped to a ring multiprocessor system, and a block diagram using dsp device is constructed. in chapter 4, the study is performed on real - time system hardware realization of atr. tms320c80 is selected as the kernel processor in multiprocessor system
為此，對一種由常用的dsp晶元組成的多處理器系統的處理器利用率進行了分析，提出了多處理器系統互連網路設計的基本原則；本章使用遺傳演算法作為實現多處理器調度的工具，提出了一種新的任務調度演算法，該演算法主要是為了解決在任務數任意、任務計算時間不相等、任務前趨關系任意、以及任務間存在通信和考慮任務存貯器要求的情況下，如何優化任務在各個處理器上的分配和執行順序，使得多處理器系統總的執行時間最小；最後對一個目標識別演算法進行了硬體實現優化分析，根據分析結果，將演算法映射到由dsp晶元組成的環形網路連接的處理器拓撲結構上，得到了多處理器系統的原理框圖。 -
