Abstract: Systems and methods relate to performing address translations in a multithreaded memory management unit (MMU). Two or more address translation requests can be received by the multithreaded MMU and processed in parallel to retrieve address translations to addresses of a system memory. If the address translations are present in a translation cache of the multithreaded MMU, the address translations can be received from the translation cache and scheduled for access of the system memory using the translated addresses. If there is a miss in the translation cache, two or more address translation requests can be scheduled in two or more translation table walks in parallel.

Abstract translation: 系统和方法涉及在多线程存储器管理单元（MMU）中执行地址转换。 可以由多线程MMU接收两个或多个地址转换请求并并行处理以将地址转换检索到系统存储器的地址。 如果地址转换存在于多线程MMU的转换高速缓存中，则可以从转换高速缓存接收地址转换，并且使用转换的地址来调度系统存储器的访问。 如果翻译缓存中存在缺失，则两个或多个地址转换请求可以在两个或多个平移的平移表中进行调度。

Abstract: Systems and methods relate to managing shared resources in a multithreaded processor comprising two or more processing threads. Danger levels for the two or more threads are determined, wherein the danger level of a thread is based on a potential failure of the thread to meet a deadline due to unavailability of a shared resource. Priority levels associated with the two or more threads are also determined, wherein the priority level is higher for a thread whose failure to meet a deadline is unacceptable and the priority level is lower for a thread whose failure to meet a deadline is acceptable. The two or more threads are scheduled based at least on the determined danger levels for the two or more threads and priority levels associated with the two or more threads.

Abstract translation: 系统和方法涉及在包括两个或多个处理线程的多线程处理器中管理共享资源。 确定两个或更多个线程的危险水平，其中线程的危险等级基于线程由于不可用的共享资源而遇到期限的潜在故障。 还确定与两个或更多个线程相关联的优先级，其中对于不能达到期限的线程而言，优先级高于不能接受的线程，并且对于不满足截止期限的线程，优先级较低。 至少基于与两个或多个线程相关联的两个或多个线程的确定的危险等级和优先级，来调度两个或更多个线程。
