Patent number: 9400667Abstract: A method, system and computer program product for optimizing memory usage associated with duplicate string objects in a Java virtual machine. The method comprises scanning a heap of the Java virtual machine at the end of the start-up process of the virtual machine to identify duplicate strings associated with the virtual machine, storing the identified strings in a string cache file, and determining whether a new string that needs to be created during start-up already exists in the string cache file. The duplicate strings are added to an interned strings table. A reference to a duplicate string is returned if a string to be created is already in the string cache file.Type: GrantFiled: December 20, 2013Date of Patent: July 26, 2016Assignee: International Business Machines CorporationInventors: Curtis E. Hrischuk, Andrew Russell Low, Peter Duncan Shipton, John Joseph Stecher

Patent number: 8627303Abstract: A method, computer program product, and system for memory optimization by partitioning extraneous information from executable virtual machine code or interpreted code. The extraneous information may be stored separately, or accessed from the original code if needed for debugging or servicing the code in the field. This approach optimizes memory usage by reducing memory footprint while maintaining accessibility of the non-executable information for debugging and other processes necessary for servicing code in the field.Type: GrantFiled: November 30, 2009Date of Patent: January 7, 2014Assignee: International Business Machines CorporationInventors: Henry Walton Adams, III, Sean Christopher Foley, Curtis E. Hrischuk, Andrew Russell Low, Peter Duncan Shipton

Publication number: 20110276981Abstract: A runtime-resource management method, system, and product for managing resources available to application components in a portable device. The method, system, and product provide for loading one or more new application components into a portable device only if maximum runtime resources required by the one or more new application components are available in the portable device assuming loaded application components within the device are using the maximum runtime resources reserved by the loaded application components, reserving maximum runtime resources required by application components when application components are loaded into the portable device, and running loaded application components using only the runtime resources reserved for the loaded application components.Type: ApplicationFiled: July 21, 2011Publication date: November 10, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: KIM CLOHESSY, JOHN DUIMOVICH, TRENT GRAY-DONALD, BERTHOLD LEBERT, RYAN SCIAMPACONE, PETER DUNCAN SHIPTON

Patent number: 6446254Abstract: In typical Java and other interpreted programming language environments, the code is stored in ROM in a semi-processed state, .class files containing byte codes. When the device is turned on, a virtual machine resolves references and links the .class file in RAM to permit desired applications to be run. In the invention, the .class files are further pre-processed to select the data which will not change or require updating. This data is packaged into memory image files containing internal data pre-linking this data. The memory image files are stored in ROM and are accessible from ROM by the virtual machine at runtime. Only elements that will be updated, such as the objects themselves, must be instantiated in RAM at runtime. This reduces the amount of RAM needed to run the application. In an environment with memory constraints, the reduction in RAM requirements permits more RAM to be made available for application use.Type: GrantFiled: August 13, 1999Date of Patent: September 3, 2002Assignee: International Business Machines CorporationInventors: Graham Chapman, John Duimovich, Trent Gray-Donald, Graeme Johnson, Andrew Low, Peter Wiebe Burka, Patrick James Mueller, Ryan Andrew Sciampancone, Peter Duncan Shipton
