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(jì)的基本原則;本章使用遺傳算法作為實(shí)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(jì)算時(shí)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(gè)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(shí)間最??;最后對一個(gè)目標(biāo)識(shí)別算法進(jìn)行了硬件實(shí)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。
