    • A method and system according to the present invention provide for sharing memory between applications running on one or more CPUs, and acceleration co-processors, such as graphics processors, of a computer system in which the memory may retain its optimal caching and access attributes favorable to the maximum performance of both CPU and graphics processor. The method involves a division of ownership within which the shared memory is made coherent with respect to the previous owner, prior to handing placing the shared memory in the view the next owner. This arbitration may involve interfaces within which ownership is transitioned from one client to another. Within such transition of ownership the memory may be changed from one view to another by actively altering the processor caching attributes of the shared memory as well as via the use of processor low-level cache control instructions, and/or graphics processor render flush algorithms which serve to enforce data coherency. Embodiments of the invention facilitate maximal access efficiency for all clients which share the data, without the incurring the overhead of moving or replicating the data between the clients.
    • 根据本发明的方法和系统提供了在一个或多个CPU上运行的应用程序和计算机系统的加速协处理器(例如图形处理器)之间共享存储器,其中存储器可以保持其优化的缓存和访问属性 达到CPU和图形处理器的最大性能。 在将视图中的共享存储器放置在下一个所有者之前,该方法涉及对共享存储器相对于先前所有者进行一致的所有权分割。 这种仲裁可能涉及所有权从一个客户端转移到另一个客户端的接口。 在这种所有权转移中,通过主动地改变共享存储器的处理器高速缓存属性以及通过使用处理器低级高速缓存控制指令和/或图形处理器渲染刷新算法,可以将存储器从一个视图改变到另一个视图, 用于强制数据一致性。 本发明的实施例便于共享数据的所有客户端的最大访问效率,而不会招致在客户端之间移动或复制数据的开销。
