    Story

    It provides the system call interface entering privileged mode as a user task runs in user(unprivileged) mode.

     

    Two types of task are handled: normal and real time tasks. Round-robin scheduler for normal tasks while priority scheduler for real time tasks. Each task is given a priority which can be dynamically changed. For a real time task a higher priority task always preempts lower priority tasks while the same priority tasks take place in turn under round-robin scheduling.

     

    The concept of virtual file system is implemented. The embedded flash in SoC can be mounted as the root file system while a ramfs is mounted as a devfs for a device node.

     

    And there are some more features. Please check it out. Any feedback on improvements, suggestion, or whatever would be appreciated.
