摘要: 在嵌入式处理器上提出一种基于硬件操作系统(HOS)的设计结构,将以往依靠操作系统复杂软件代码实现的系统调度、控制等处理过程通过可编程微码执行方式由处理器硬件执行。通过在51处理器内核的基础上添加任务调度等HOS设计,实现了一款针对家电嵌入式系统带有HOS支持的处理器。将该设计下载到FPGA芯片中替换空调控制器中的嵌入式处理器,测试结果表明,与原系统相比较,该处理器执行效率更高。

Abstract: This paper proposes a kind of embedded processor with Hardware OS(HOS) architecture. In this processor, the task scheduling and management can be achieved by the hardware. An HOS processor with i51-core is designed and downloaded to the FPGA to test. Experimental results show that the efficiency of scheduling is improved by using the HOS processor.
