几十年前,“嵌入”(embedded)一字大多还仅见于军事应用。例如,战斗机的对抗电子设备中嵌入了计算机板,在坦克火控系统中置有嵌入微处理器等。 随着集成电路的成本不断降低,性能日益提高,嵌入式系统在消费类产品、汽车、工商业设备和通信设备等部门迅速普及。因此,委托设计人员不仅要接受技术性能要求的挑战,同时还必须了解最终用户的各种应用,办公室和家用fax、银行柜员机、工厂生产线上复杂的控制器彼此是绝对不同的。家庭被认为是嵌入式微控制器未来的巨大潜在市场。据估计,目前一个中等家庭在各类应用器具中共有30个左右的嵌入式微处理器,预计这一数字将迅速增长。
Decades ago, the word “embedded” was mostly used only in military applications. For example, fighter confrontation electronic equipment embedded in the computer board, embedded in the tank fire control system embedded microprocessor. As the cost of integrated circuits continues to decrease and performance increases, embedded systems are rapidly gaining popularity in consumer products, automotive, industrial and commercial equipment, and communications equipment. Therefore, commissioning designers not only to meet the technical performance requirements of the challenge, but also must understand the end-user applications, office and home fax, bank teller machines, factory complex controller on the production line are absolutely different from each other. The family is considered a huge potential market for the future of embedded microcontrollers. It is estimated that a medium-sized family currently has about 30 embedded microprocessors in various types of appliances, and this number is expected to grow rapidly.
