摘要
使用实时内核来进行多任务的管理是目前嵌入式应用的一个趋势,面向设备的嵌入式应用由于其资源受到严重限制,具有针对性强的特点,本文在一个8位嵌入式芯片上设计并实现了一个面向设备的抢占式实时多任务内核WebitV,它在总体上保留了传统内核的主要特性,但在任务调度,优先级分配以及存储器管理等几个方面进行了改进,使它更适合于设备计算,为普适计算提供了一个底层平台。
It is a trend to use real-time kernel in embedded application- Because of its serious scarcity resources the application of device level is different from other embedded application. A new preemptive multi-task kernel-WebitV based on an 8-bit embedded chip is presented in this paper. It remain the main character of traditional embedded kernel but have been improved in several portion, such as task schedule, priority assignment and memory management. After the redesign WebitV are more fit for device level computing and it can provide a low platform for ubiquitous computing.
