Abstract: For each access request received at a shared cache of the data processing device, a memory access pattern (MAP) monitor predicts which of the memory banks, and corresponding row buffers, would be accessed by the access request if the requesting thread were the only thread executing at the data processing device. By recording predicted accesses over time for a number of access requests, the MAP monitor develops a pattern of predicted memory accesses by executing threads. The pattern can be employed to assign resources at the shared cache, thereby managing memory more efficiently.

Abstract translation: 对于在数据处理设备的共享高速缓存处接收到的每个访问请求，如果请求的线程是唯一的线程，则存储器访问模式（MAP）监视器预测访问请求将访问哪个存储体和对应的行缓冲器 在数据处理装置执行。 通过针对多个访问请求记录对时间的预测访问，MAP监视器通过执行线程来开发预测的存储器访问的模式。 可以使用该模式来在共享高速缓存上分配资源，从而更有效地管理存储器。
