基于SoC嵌入式片上系统应用研究

Application Research on Embessed System on Chip Based on SoC

以片上系统(SoC)为代表的嵌入式应用系统拉开了嵌入式系统发展的大幕,极大的推动了IT产业的发展,给人们的生产、生活带来深远的影响。嵌入式系统用在一些特定专用设备上,通常这些设备的硬件资源(如处理器、存储器等)非常有限,而且对成本敏感,有时对实时性要求较高等。常见的嵌入式系统如手机、PDA、电子词典、掌上电脑、VCD/DVD/MP3 Player、数码相机、游戏机、机顶盒、路由器等,这类嵌入式应用系统对成本比较敏感。还有一些对性能和实时性要求比较高,如通信系统,医疗仪器,航空航天设备以及军事武器上的一些嵌入式应用系统。

In system on chip （SoC） as the representative of the embedded application system of embedded system development was pulled open big screen, which greatly promoted the development of the IT industry, to the production of people, life brings far-reaching influence Embedded system used in a number of specific equipment, usually these hardware resources （such as CPU, memory, etc） is very limited, but also for cost sensitive, sometimes the real-time etc.. Our common embedded systems such as mobile phone, PDA, electronic dictionary, PDA,VCD / DVD / MP3 Player, digital cameras, gaming machines, routers, set-top box, this kind of embedded application system on cost sensitive. Some of the properties and high real-time requirement, such as communication system, medical equipment, aerospace equipment and weapons on a number of embedded application system.
