   將施工搭接網(wǎng)絡(luò)的每一搭接關(guān)系改用新增的工序相連，并將該搭接關(guān)系的時距定義為這新增工序的持續(xù)時間，把這一新工序稱為時距工序。
2. 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芯片組成的多處理器系統(tǒng)的處理器利用率進(jìn)行了分析，提出了多處理器系統(tǒng)互連網(wǎng)絡(luò)設(shè)計的基本原則；本章使用遺傳算法作為實現(xiàn)多處理器調(diào)度的工具，提出了一種新的任務(wù)調(diào)度算法，該算法主要是為了解決在任務(wù)數(shù)任意、任務(wù)計算時間不相等、任務(wù)前趨關(guān)系任意、以及任務(wù)間存在通信和考慮任務(wù)存貯器要求的情況下，如何優(yōu)化任務(wù)在各個處理器上的分配和執(zhí)行順序，使得多處理器系統(tǒng)總的執(zhí)行時間最??；最后對一個目標(biāo)識別算法進(jìn)行了硬件實現(xiàn)優(yōu)化分析，根據(jù)分析結(jié)果，將算法映射到由dsp芯片組成的環(huán)形網(wǎng)絡(luò)連接的處理器拓?fù)浣Y(jié)構(gòu)上，得到了多處理器系統(tǒng)的原理框圖。
