Title: Coalescing memory accesses from multiple threads in a parallel processing system
Inventor: NYLAND LARS
IPC: G06F9/38
Filed: 2009-03-04
Abstract: A parallel processing system receives an application memory access request 400. The request contains a number of separate thread memory access requests to be carried out by separate threads in a thread group. The system generates a physical memory access request 430 for the first thread access request. The physical access request is set to the maximum size possible. The system then identifies any other thread access requests that can be satisfied by the same physical access request. The system uses a thread mask 446 to identify the thread access requests satisfied by the physical access request. This is then repeated for the other thread access requests until sufficient physical access requests have been generated to satisfy the all the thread access requests. A pending request table 410 may be used to hold entries 412 identifying the thread access requests.
