基于多核处理器的弹载嵌入式系统设计研究

Research about designing of missile-borne embedded system based on multicore processor

基于实现目标探测识别以及高精度目标信息测量等复杂处理算法的目的,采用单片多核DSP TMS320C6678构成弹载高速多任务实时嵌入式处理平台,通过数据流处理模式的并行软件设计方法,将系统处理任务均衡分配到各处理器内核,以实现实时并行处理,提升弹载信息处理系统的功能和性能。开展基于多核处理器的并行软件研制、充分发挥多核处理能力将成为弹载嵌入式系统软件设计的新课题。

For the purpose of implementing complicated algorithms such as target detection, target recognition and high-precision target information measurement, the missile-borne embedded real time processing platform will be constructed with the muhicore DSP TMS320C6678. By the parallel software design based on data flow model, the system processing components can be split and mapped to each core to keep the processing pipeline well-balanced and flowing regularly, that is to achieve multi-task real time parallel processing and improve the ability of the missile-borne embedded system. The introduction of muhicore processors to the missile-borne embedded system provides a new challenge for the software developers,who must now master the programming techniques necessary to fully exploit muhicore processing potential.
