摘要： A system page is implemented to provide direct access to operating system data structures by user tasks. Frequently accessed data structures are located in the system page, and may be linked against during linking. The system page memory locations are mapped into user tasks as read-only memory locations, allowing read-only memory accesses during run-time. The system page reduces execution overhead without sacrificing system security.

摘要： A protection domain system is implemented to provide protection for applications executing in a computing environment. Protection domains are allocated system resources and may contain executing tasks. The protection domain system may allow tasks to access resources in other protection domains to which attachments have been made. Attachment is transparent to the software developer. The protection domain system provides flexibility in implementing operating system services and defining protection hierarchies.

摘要： A task stack and a context pointer in a task control block (TCB) are implemented to provide more efficient context switching. Additionally, multiple routines each of which saves or restores a certain combination of volatile registers is implemented. A task can store in its task control block a routine identifier to select from the multiple routines a set of routines for saving and restoring volatile registers during context switching. On the occurrence of an event that may lead to a context switch a scheduler selects based on the routine identifier a routine that only saves registers used by the task, thereby, reducing execution overhead. The registers are saved on the task stack and a context pointer to the registers is saved in the TCB. In the event a context switch is necessary, it is not necessary to copy the registers to the TCB because the context pointer is in the TCB. A non-volatile register indicator that indicates whether non-volatile registers are used is stored in the task control block. The non-volatile registers are only saved if used, also reducing execution overhead. Furthermore, a storage area is implemented for saving task context for the task when it is interrupted during context switch in. Upon the occurrence of an interrupt the task context is saved in the storage area. If the interrupt leads to a second task which has a higher priority being made ready, the second task is switched in without first returning to switch-in the task.
摘要翻译：实施任务堆栈和任务控制块（TCB）中的上下文指针以提供更有效的上下文切换。此外，实现了每个保存或恢复易失性寄存器的特定组合的多个例程。任务可以在其任务控制块中存储例程标识符，以从多个例程中选择用于在上下文切换期间保存和恢复易失性寄存器的一组例程。在可能导致上下文切换的事件的发生中，调度器基于例程标识符来选择仅保存由任务使用的寄存器的例程，从而减少执行开销。寄存器保存在任务堆栈中，寄存器的上下文指针保存在TCB中。如果需要上下文切换，则不需要将寄存器复制到TCB，因为上下文指针位于TCB中。指示是否使用非易失性寄存器的非易失性寄存器指示符存储在任务控制块中。非易失性寄存器仅在使用时才被保存，同时也降低了执行开销。此外，当在上下文切换期间被中断时，实现用于保存任务的任务上下文的存储区域。在发生中断时，将任务上下文保存在存储区域中。如果中断导致具有较高优先级的第二任务准备好，则第二任务被切换而不首先返回以切换任务。
