摘　　要：Webit是一个独立的、低成本的网络服务器,由东大新业技术股份有限公司研制成功.iDCX 51是Intel公司开发的实时操作系统,在工业控制等领域已成功应用,为使其能在Webit中也能够运行,以增强Webit的性能,对此本文以Webit内部单片机AT90S8515为例介绍iDCX 51往Webit中移植的设计与实现,并对移植后的时间性能进行了测试与对比分析,得知其任务切换时间与最大中断禁止时间这两项关键的时间性能指标分别减少33.3%和31.9%,表明系统移植后实时性得到了提高.Webit is a independent Web Server with a low cost, it has been developed successfully by Neu-Era L.D. iDCX 51 is a real-time operating system developed by Intel corporation, it was successfully used in industrial control and so on, in order to make sure that it can also be operated in Webit, and enhance the Webit＇s performance, so the design, implementation of transplanted process about iDCX 51 to the Webit are introduced in this paper detailedly by taking Webit＇s singlechip （AT90S8515） as an example, and also the test and compared analysis about the time capability after transplanting to Webit, knowing that the two key time capability of switching task time and max banning interrupt time have separately decreased by 33.3% and 31.9% after calculating, which indicates the real-time capability of the system has improved after transplanting.
