Title: Method for operating of buffer memory and related apparatus
Inventor: SUPENSAA WAAFUAN N
IPC: G06F12/08
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a system for adaptively managing a predicted buffer memory prefetch operation for optimizing buffer memory hit in a data storage system. SOLUTION: An arriving data access request(DAR) stream is monitored for a specific data access pattern, and when a successive access pattern(SAP) is detected, a buffer memory prefetch storage rule is switched to be in a cyclic overwriting mode (COM), and an optimal succesisve access performance can be attained. When the successive access pattern disappears, a non-successive access pattern(NAP) is detected, the buffer memory prefetch storage rule is switched to be in a non-successive or block overwriting mode(BOM) according to it, and the 'reuse' hit of a data block in a data buffer is maximized. The detection of the successive access pattern is attained by using a threshold value adapted to the size of the arriving DAR.
