    • Requests from a plurality of different agents (10) are passed to a request handler via a request concentrator. In front of the request concentrator the requests are queued in a plurality of queues (12). A first one of the agents is configured to issue a priority changing command with a defined position relative to pending requests issued by the first one of the agents (10) to the first one of the queues (12). An arbiter (16), makes successive selections selecting queues (12) from which the request concentrator (14) will pass requests to the request handler (18), based on relative priorities assigned to the queues (12). The arbiter (16) responds to the priority changing command by changing the priority of the first one of the queues (12), selectively for a duration while the pending requests up to the defined position are in the first one of the queues (12). Different queues may be provided for read and write requests from the first one of the agents. In this case, the priority raising request from the agent may be used to raise the priority level of the write queue temporarily to the level of the read queue, until all write requests issued before the priority raising command from the agent have been passed to the request handler.
    • 来自多个不同代理(10)的请求经由请求集中器传递给请求处理程序。 在请求集中器前面,请求被排队在多个队列(12)中。 代理的第一个被配置为发布具有相对于由代理(10)中的第一个发起到队列(12)中的第一个的未决请求的定义位置的优先级改变命令。 仲裁器(16)根据分配给队列(12)的相对优先级,对请求集中器(14)进行连续选择选择队列(12),将请求发送到请求处理器(18)。 仲裁器(16)通过选择性地改变队列(12)中的第一队列(12)的优先级来响应优先级改变命令持续一段时间,而直到定义的位置的待决请求在队列(12)中的第一队列中, 。 可以为来自第一代理的读写请求提供不同的队列。 在这种情况下,可以使用来自代理的优先级提升请求将临时写入队列的优先级提升到读队列的级别,直到来自代理的优先级提升命令之前发出的所有写请求已经被传递到 请求处理程序。

    • A method (60) for controlling multiple tasks in a real-time operating system (110, 170) assigns priorities to two or more tasks (114, 115; 174, 175). A first task (114; 174) is assigned to be a More Important Task. A second task (115; 175) is assigned to be a Less Important Task. Each task is explicitly informed of its budget allocations. A Guaranteed Budget Margin is then allocated to the More Important Task along with a More Important Guaranteed Budget. A Less Important Guaranteed Budget is also allocated to the Less Important Task. At some point during execution, the higher priority or More Important Task (114; 174) may then determine that the More Important Task no longer requires the Guaranteed Budget Margin, in which case, a Conditionally Guaranteed Budget Margin is then allocated to the Less Important Task (115; 175).
    • 用于控制实时操作系统(110,170)中的多个任务的方法(60)将优先级分配给两个或多个任务(114,115; 174,175)。 第一个任务(114; 174)被分配为更重要的任务。 第二个任务(115; 175)被分配为不重要的任务。 每个任务明确地通知其预算拨款。 然后将保证的预算保证金分配给更重要的任务以及更重要的保证预算。 较不重要的保证预算也分配给不重要任务。 在执行期间的某个时间点,较高优先级或更重要任务(114; 174)可能会确定“更重要任务”不再需要保证预算保证金,在这种情况下,有条件保证的预算保证金将分配给不太重要 任务(115; 175)。
