  • Patent number: 8627303
    Abstract: 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.

  • Publication number: 20120017204
    Abstract: 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.

  • Patent number: 7715307
    Abstract: Communication connection control systems and methods are disclosed. If a control failure recovery function is to be enabled for a data communication connection established by a communication connection controller by communicating control information with a remote controller, an indication that the control failure recovery function is supported at the controller is included in the control information communicated with the remote controller. Each of the controller and the remote controller may support, for example, either or both of a local control information recovery function or a resynchronization function to reduce the amount of time that the data connection is interrupted during a temporary failure of one of the controllers.

  • Publication number: 20090300054
    Abstract: A system is disclosed for formulating structure descriptions from data. In some embodiments, data arrives with an unknown format. The data may be ad hoc data that is considered semi-structured. Disclosed embodiments analyze chunks of the data to determine tokens. Tokens are analyzed to identify base types and compound types such as structs, unions, and arrays. Descriptions are generated and undergo scoring and rewriting for optimization. The generated descriptions may be fed to a data description language such as Processing Ad Hoc Data System (PADS) and compiled for processing the raw data. In some embodiments, the raw data is parsed, printed, or reformatted using the generated descriptions.

  • Patent number: 7227485
    Abstract: The waveform conform control circuit includes a waveform generator, an amplitude adjustment device and an offset device. The waveform generator produces a current waveform. The amplitude adjustment device receives amplitudes amplitude data and produces a predetermined scale factor which is applied to the basic current waveform to produce a scaled current waveform. The offset device is a digital to analog converter for receiving offset data and producing a predetermined scale value that is added to the scaled waveform to produce a final current waveform. A method a digitally generated waveform is also disclosed. An offset circuit using current steering digital to analog and a current mirror is also disclosed.

  • Patent number: 6446254
    Abstract: 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.
