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 computer system is provided comprising a core operating system and a system space having a number of memory locations. The core operating system creates a number of protection domains to partition the system space. Each of the partitions includes a partition operating system and a partition user application. Each partition operating system provides resource allocation services to the respective partition user application within the partition.

摘要： A computer system and method for operating a computer system is provided which comprises a core operating system and a system space having a number of memory locations. The core operating system is arranged to create a number of protection domains to partition the system space into a core operating system space and a plurality of partitions. A partition operating system, a partition user application, and a partition alarm handler is provided in each partition. Each partition operating system provides resource allocation services to the respective partition user application within the partition. An alarm dispatcher and a system alarm handler is provided in the core operating system space. The alarm dispatcher is configured to receive alarms and to dispatch the alarms to one of the alarm handlers.
摘要翻译：提供了一种用于操作计算机系统的计算机系统和方法，其包括核心操作系统和具有多个存储位置的系统空间。核心操作系统被设置成创建多个保护域以将系统空间划分为核心操作系统空间和多个分区。在每个分区中提供分区操作系统，分区用户应用程序和分区警报处理程序。每个分区操作系统向分区内的相应分区用户应用提供资源分配服务。在核心操作系统空间中提供了一个报警调度器和一个系统报警处理程序。报警分配器配置为接收报警，并将报警发送到其中一个报警处理程序。

摘要： A system and method donates time from a first process to a second process. The method includes determining a time slice for each of a plurality of processes to generate a schedule therefrom. The method includes determining a time donation scheme for the first process, the time donation scheme indicative of a donation policy in which the execution time of the first process is donated to the second process. During execution of the processes, the method includes receiving a request from the first process for a time donation to the second process and executing the second process during the time slice of the first process.
摘要翻译：系统和方法将时间从第一个进程提供给第二个进程。该方法包括确定多个进程中的每一个的时间片以从其生成日程表。所述方法包括：确定用于所述第一过程的时间捐赠方案，所述捐赠方案指示将所述第一处理的执行时间捐赠给所述第二进程的捐赠策略。在执行过程期间，该方法包括从第一进程接收对第二进程的时间捐赠的请求，并在第一进程的时间片段期间执行第二进程。

摘要： A system and method deterministically switches context in a real-time scheduler to guarantee schedule periodicity. The method includes determining a time slice for each of the plurality of processes. The method includes determining a time slice switch duration between consecutive ones of the time slices. The method includes determining a starting point for each time slice. The method includes generating a schedule as a function of the time slices, the time slice switch durations, and the starting points of the time slices. The schedule includes an order for each of the time slices for a respective one of the plurality of processes. Each of the time slices and each of the time slice switch durations are required to run for their entire duration to guarantee a periodicity of the schedule.
