- 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
为此，对一种由常用的dsp芯片组成的多处理器系统的处理器利用率进行了分析，提出了多处理器系统互连网络设计的基本原则；本章使用遗传算法作为实现多处理器调度的工具，提出了一种新的任务调度算法，该算法主要是为了解决在任务数任意、任务计算时间不相等、任务前趋关系任意、以及任务间存在通信和考虑任务存贮器要求的情况下，如何优化任务在各个处理器上的分配和执行顺序，使得多处理器系统总的执行时间最小；最后对一个目标识别算法进行了硬件实现优化分析，根据分析结果，将算法映射到由dsp芯片组成的环形网络连接的处理器拓扑结构上，得到了多处理器系统的原理框图。 - In designing or selecting a topology for a parallel processing system , one fundamental consideration is system - level fault tolerance . in order to improve the fault tolerance , the paper analyses from the two following sides : one is by adding the less links related to the original networks , modifying the topology of the original one , we get higher fault tolerance of the new network ; the other is under the same topology network , ignoring the likelihood of one processor and ail its neighbors failing at the same time , or considering the distribution of the faulty nodes , that is studying the fault tolerance under the conditional connectivity or cluster - fault - lolerance
本文以提高网络的容错度为目的，从两个方面分析互连网络的容错性质：一是在原网络基础上增加少量连接，使新型网络具有更高的连通度(容错度为连通度减1 ) ；二是在给定互连网络拓扑结构下，考虑故障处理器发生的概率和故障处理器的分布状况，在其中的某一具体条件下，即在条件连通度和簇容错下分析互连网络的容错性能，从而得到更高的网络容错度。 - Finally discusses several class different multi - dsp extended architecture based on vvp platform . chapter 3 analyzes the significance of dynamic reconfiguration of multi - dsp parallel processing system , introduce run - time reconfiguration technique of fpga . with comparison of the common used dynamic communication network in parallel processor system , proposes the new dynamic reconfigurable multi - dsp system architecture based on run - time reconfigurable fpga
