嵌入式的发展(中文4500字,英文2700字)
近年来，随着计算技术、通信技术的飞速发展，特别是互联网的迅速普及和3C（计算机、通信、消费电子）合一的加速，微型化和专业化成为发展的新趋势，嵌入式产品成为信息产业的主流。嵌入式产品的发展，往往要求嵌入式操作系统有网络和图形的功能。利用源代码开放的Linux搭建的嵌入式操作系统，由于强大的网络功能和低成本，近来得到了越来越多的应用。主要体现在以下几个方面[1]。
① 嵌入式应用软件的开发需要强大的开发工具和操作系统的支持
随着因特网技术的成熟、带宽的提高，ICP和ASP在网上提供的信息内容日趋丰富、应用项目多种多样。像电话手机、电话座机及电冰箱、微波炉等嵌入式电子设备的功能不再单一，电气结构也更为复杂。为了满足应用功能的升级，设计师们一方面采用更强大的嵌入式处理器如32位、64位RISC芯片或信号处理器DSP增强处理能力；同时还采用实时多任务编程技术和交叉开发工具技术来控制功能复杂性，简化应用程序设计、保障软件质量和缩短开发周期。
The development of Flushbonading
In recent years, with the rapid development of computing technology, communication technology, especially the rapid popularization of Internet and 3 c (computer, communications, consumer electronics) the acceleration of unity, become a new trend in the development of miniaturization and specialization, embedded products become the mainstream of information industry.The development of embedded products, often require an embedded operating system have the functions of network and graphics.Built using open source Linux embedded operating system, due to the powerful network function and low cost, has been more and more used recently.[1] is mainly embodied in the following several aspects.(1) the embedded application software development need strong development tools and operating system supportWith the improvement of the Internet technology maturity, bandwidth, ICP, and the content of ASP provides information on the Internet has become increasingly rich and varied applications.As phone fixed phone, telephone and refrigerators, and microwave ovens embedded electronic equipment function is no longer a single, electric structure is more complex.In order to satisfy the application upgrade function, the designers on the one hand, a more powerful embedded processors, such as 32-bit and 64 - bit RISC chips or signal processor DSP enhance processing capacity;Also USES the real-time multitasking |
