%X 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.
