摘要
从1981年第一个商业嵌入式实时操作系统VRTX/OS的出现,嵌入式实时操作系统已经过三十多年的发展。本文对嵌入式相关的文献进行了调研,发现随着嵌入式芯片多核技术的日趋成熟和广泛应用,嵌入式实时操作系统对多核处理器提供了一定的支持,包括对称多核(SMP)和非对称多核(AMP),但也仍然存在多核并发控制、任务调度等问题。在分析RTOS的研究现状后,得出了今后RTOS的研究热点有异构多核支持和物联网应用。
The RTOS has been developed over three decades till now after the first available commercial RTOS which namedVTRX/OS.After the study on embedded related literatures, it shows that with the development of Multi-core technology and widelyuse of Multi-core chips, the RTOS is becoming to support the Multi-core features include SMP and AMP, in order to fully use thepotential of hardware, but still have some problem such as concurrency control and task allocation. So the next hot research filed ofRTOS is the support of Heterogeneous multiprocessor. Besides the IOT also could be an important application filed for RTOS.
