As another hint, the adaptive software process guarantees the agility of information, which is intercrossed by architecture refactoring . the u-w-a hierarchical model of software process, analyses of task process model and entity process model, and of contents and contexts of cooperation, are discussed, which proves the complexity of software process and necessities of adaptive and cooperative software process . in the last, some constructive suggestions of building cooperative platform are given 论文通过对软件过程模型建立u-w-a层次模型,对任务过程模型与实体过程模型的对比分析及协同内容与过程上下文的对比分析,论述了软件开发过程自身的复杂性及建立一个可适应协同开发过程的必要性,最后对过程所必需工作平台的搭建给出了几点建设性的意见。
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。
