20160098200 | IN-MEMORY POPCOUNT SUPPORT FOR REAL TIME ANALYTICS - A Processing-In-Memory (PIM) model in which computations related to the POPCOUNT and logical bitwise operations are implemented within a memory module and not within a host Central Processing Unit (CPU). The in-memory executions thus eliminate the need to shift data from large bit vectors throughout the entire system. By off-loading the processing of these operations to the memory, the redundant data transfers over the memory-CPU interface are greatly reduced, thereby improving system performance and energy efficiency. A controller and a dedicated register in the logic die of the memory module operate to interface with the host and provide in-memory executions of popcounting and logical bitwise operations requested by the host. The PIM model of the present disclosure thus frees up the CPU for other tasks because many real-time analytics tasks can now be executed within a PIM-enabled memory itself. The memory module may be a Three Dimensional Stack (3DS) memory or any other semiconductor memory. | 04-07-2016 |
