Hierarchical memory with dedicated high speed buffers

摘要

A hierarchical memory for a data processing system which is comprised of a number of different independent storage modules and a main memory backing store. Each data handling element of the system has an independent storage module associated with it as a dedicated buffer. A larger high speed main storage is used as a backing store. Each data handling element presumes that any data it needs is located in its dedicated buffer. If the data is not in the dedicated buffer, the data handling element scans all the other buffers until the desired data is located.
