Dynamically-adjusted host memory buffer
Dell Products, Lp
October 12, 2017 - N°20170293562

Host memory buffer is dynamically adjusted based on performance. As memory pages are accessed, one or more counts of the memory pages are maintained. If the counts indicate some of the memory pages are identical, then a portion of host system memory allocated to buffer cache may be reduced or decremented in response to repetitive access. However, if the counts ...
Reducing memory access bandwidth based on prediction of memory request size
Qualcomm Incorporated
