The Research Of The Embedded Real-time Operation System

The embedded real-time operation system is the base and the development flat of the embedded application, relates to many techniques about hardware and software o The kernel of the embedded real-time operation system lies in the port (adapting a real-time kernel to a different microprocessor or microcontroller) of the embedded real-time operation system create tasks extend function and the research on the kernel and the basal function of the embedded real-time operation system, which are the difficulties of the embedded real-time operation system oBase on the expatiate on the concept and the characteristic about the embedded real-time operation system, in an instance of μ C/OS-II; the kernel of μ C/OS -II is discussed, the task scheduling of μ C/OS-II and the interrupts under μ C/OS - II are analyzed; μ C/OS - II's clock tick and the process about the initialization and starting of μ C/OS-II are described; the basal function of μ C/OS - II including task management time management memory management and intertask communication and synchronization is introduced Base on the sufficient cognition of μ C/OS -II, the condition and the process about the port of μ C/OS -II are analyzed, try to porting μ C/OS-II to TMS320C24x DSP and succeeded?Besides these, create tasks and extend function are attempted Research achievement as below:The research on the kernel and the basal function of μ C/OS-II?It is the base of the application of μ C/OS-II The research on the port of the μ C/OS-II the condition and the process about the port of μ C/OS-II are analyzed, with the example that porting μ C/OS-II toTMS320C24 x DSP, the detailed process about the port of μ C/OS-II are explainedthe configuration constants used in μC/OS-II and how to override the defaultconfiguration supplied in UCOS2.LIB are introduced, With two example , we realizethe necessary steps to get an application running Extend the function of μC/OS-II The disposal of ARP message and IP message , lookup the PCI equipment and driving serial port are actualized in μC/OS-II...
