This paper describes the features of Embedded Real-time OS,μC/OS-Ⅱ,and discusses the realization of porting μC/OS-Ⅱ to DSP TMS320C6416 in detail.It also presents the most important and difficult problems in porting μC/OS-Ⅱ,tests the core of the ported system,and cuts the latter as well.Multi-tasks running in the ported system shows that the ported program works steadily and reliably,many performance parameters meet the basic demands of embedded development.
