    Abstract: Multiple parallel passive threads of instructions coordinate access to shared resources using "active" and "proactive" semaphores. The active semaphores send messages to execution and/or control circuitry to cause the state of a thread to change. A thread can be placed in an inactive state by a thread scheduler in response to an unresolved dependency, which can be indicated by a semaphore. A thread state variable corresponding to the dependency is used to indicate that the thread is in inactive mode. When the dependency is resolved a message is passed to control circuitry causing the dependency variable to be cleared. In response to the cleared dependency variable the thread is placed in an active state. Execution can proceed on the threads in the active state. A proactive semaphore operates in a similar manner except that the semaphore is configured by the thread dispatcher before or after the thread is dispatched to the execution circuitry for execution.

    Abstract translation: 指令的多个并行被动线程使用“主动”和“主动”信号量协调对共享资源的访问。 主动信号量将消息发送到执行和/或控制电路,以使线程的状态发生变化。 线程调度程序可以响应未解决的依赖关系将线程置于无效状态,这可以由信号量指示。 与依赖关系对应的线程状态变量用于指示线程处于非活动模式。 当依赖关系被解析时,消息被传递给控制电路,导致依赖变量被清除。 响应于清除的依赖变量,线程处于活动状态。 处于活动状态的线程可执行。 主动信号量以类似的方式运行,除了信号量由线程分派器在线程发送到执行电路执行之前或之后配置。

    Abstract: According to one embodiment, a computer system is disclosed that includes a memory and a memory controller coupled to the memory. The memory controller includes an arbitration unit that may be programmed to operate according to a first arbitration mode or a second arbitration mode. The computer system also includes a first device and a second device coupled to the arbitration unit. According to a further embodiment, the first device is assigned a higher priority classification than the second device for accessing the memory while the arbitration unit is operating according to the first arbitration mode. In addition, the first device and the second device are assigned equal priority classifications for accessing the memory while the arbitration unit is operating according to the second arbitration mode.

    Abstract: A first processor 101, such as a central processing unit (CPU), is in a cache coherency domain with a first set of coherency rules 109. Another processor 105, such as a graphics processing unit (GPU), is in a different coherency domain 111 with a second set of coherency rules. The first processor has a level 1 processor cache 103 (L1 cache) and a lower level processor cache 107. The second processor has a level 1 graphics cache 104 (L1 cache) and a lower level cache 108. The first processor uses the first set of coherency rules with the lower level graphics cache. The second processor uses the second set of coherency rules with the lower level graphics cache. The lower level graphics cache may be a mid-level or last level cache. The first processor may snoop the lower level graphics cache.
