Memory management system for a data processing system

A method of operating a memory management system for processing data files, said system comprising an access flow regulator, a plurality of high speed low storage capacity memories and a lower speed high storage capacity bulk memory, said high speed memories have a first data rate, said bulk memory has a second data rate substantially lower than said first data rate, said method comprises the steps of:

• operating said access flow regulator for generating requests for the reading and writing of said memories;
• initiating the reading of a data file by transmitting a write request from said access flow regulator to one of said high speed memories, said data file has a first portion and an excess portion;
• transmitting a read request for a data file from said access flow regulator to a one high speed memory storing a first part of said data file;
• reading said first portion of said data file from said one high speed memory;
• transferring said excess portion of said data file from said bulk memory to said one high speed memory;
• reading out said excess portion of said data file from said one high speed memory;
• and
• transmitting said first part and said excess portion said data file to said access flow regulator.

A memory management system adapted to process data files, said system comprises:

• a plurality of low storage capacity high speed memories and a lower speed high storage capacity bulk memory, said high speed memories have a first data rate and said bulk memory has a second data rate lower than said first data rate;
• an access flow regulator for generating requests for the reading and writing of files by said memories;
• apparatus for operating said access flow regulator to initiate the writing of a data file stored in said memories by transmitting an access read request to the one of said high speed memories;
• apparatus for writing a first part and excess part of said data file into said one high speed memory;
• apparatus for transferring said excess part of said data file from said one high speed memory to said bulk memory while leaving the first part of said data file in said one high speed memory;
• apparatus for subsequently transmitting a read request for said data file from said access flow regulator to said one high speed memory;
• apparatus for reading said first part in said one high speed memory;
• apparatus for transferring said excess part of said data file from said bulk memory to said one high speed memory;
• apparatus for reading out said first part and said excess part of said data file from said high speed memory;
• and
• apparatus for transmitting said read out data file to said access flow regulator.
