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.
