摘要
在智能间隔装置中提高系统的主频,装置的发热与成本会急剧地增加,但性能并不会成倍地提高。阐述了在智能间隔装置中使用多核处理器其硬件及软件上的优越性。通过一个应用实例,分析了多核装置的内核引导顺序及引导方式,解析了内核间内存分配模式,剖析了多核的中断处理方式、多核操作的软件可靠性和数据安全性,并详细说明了智能间隔装置中内核间任务分解的方式。相对于单核处理器而言,在智能间隔设备中使用多核处理器,通过合理的任务分解和中断向量的分配,会极大地提高系统的运算速度,但系统的发热及功耗相对增加很少,可以大大提高设备的性能,降低设备的成本。
By improving system frequency in smart bay equipment,the device heating and cost will increase sharply,but the device performance would not increase doubled.This paper analyses the hardware advantage and software advantage of multicore processor used in smart bay quipment.Through an application example,this paper analyses the multicore boot mode and boot sequence,parses the memory arrangement among cores,probes the multicore interrupt dealing mode,construes the software security and data reliability about multicore operation,and expounds the task distribution among cores in smart bay equipment.Relative to a single core processor,when multicore processor is used,the calculation speed can be greatly increased by logical task arrangement or interrupt distribution,but the system heating and power consume increase relatively little,and then the performance improves greatly,and the equipment price reduces significantly.
