The movie clip based application defines one or more movie clip images for display. The image application provides one or more images for display with the one or more movie clip images. The compositing application operates to composite the one or more movie clip images with the one or more images of the image application for viewing on a display. | 08-06-2009 |
| 20100040346 | SYSTEM HAVING MOVIE CLIP OBJECT CONTROLLING AN EXTERNAL NATIVE APPLICATION - A system comprises a movie clip environment in which a movie clip object is defined, and a native application that is external to the movie clip environment. The native application renders an image to an off-screen surface of the system. A composition manager is responsive to communications from the movie clip object to control where the off-screen surface is to be rendered on a display screen. The composition manager may be responsive to communications from the movie clip object to direct the native application to control one or more properties of the image of the off-screen surface. | 02-18-2010 |
| 20100253693 | SYSTEM FOR ACCELERATING COMPOSITE GRAPHICS RENDERING - A system aids composited graphics rendering. A script and corresponding virtual machine engine code may be stored in memory. An off-screen buffer is generated in the memory by the script. The off-screen buffer includes an extended stage having first a buffer portion. The buffer portion may include pre-rendered graphical object. An on-screen buffer may include a composition of the pre-rendered graphical objects of the extended stage. The script renders a graphical change to the on-screen buffer using independent block copying, from the extended stage to corresponding target areas in the on-screen buffer, of one or more of the pre-rendered graphics of the extended stage area affected by the graphical changes. | 10-07-2010 |
| 20110107342 | PROCESS SCHEDULER EMPLOYING ORDERING FUNCTION TO SCHEDULE THREADS RUNNING IN MULTIPLE ADAPTIVE PARTITIONS - A system is set forth that includes a processor, one or more memory storage units, and software code stored in the one or more memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality, of adaptive partitions has one or more corresponding scheduling attributes that are assigned to it. The software code further includes a scheduling system that is executable by the processor for selectively allocating the processor to run the process threads based on a comparison between ordering function values for each adaptive partition. The ordering function value for each adaptive partition is calculated using one or more of the scheduling attributes of the corresponding adaptive partition. The scheduling attributes that may be used to calculate the ordering function value include, for example, 1) the process budget, such as a guaranteed time budget, of the adaptive partition, 2) the critical budget, if any, of the adaptive partition, 3) the rate at which the process threads of an adaptive partition consume processor time, or the like. For each adaptive partition that is associated with a critical thread, a critical ordering function value also may be calculated. The scheduling system may compare the ordering function value with the critical ordering function value of the adaptive partition to determine the proper manner of billing the adaptive partition for the processor allocation used to run its associated critical threads. Methods of implementing various aspects of such a system are also set forth. | 05-05-2011 |

| 20110072060 | FILE SYSTEM HAVING TRANSACTION RECORD COALESCING - An electronic data system comprises memory storage having stored data, file system software, and a transaction file. The transaction file is maintained by the file system software, and includes a plurality of transaction records corresponding to transactions that have been or are to be executed on one or more files and/or the or more directories of the file system. The file system software operates to organize and maintain the stored data in the files and directories and also to coalesce multiple transaction records meeting one or more criteria into fewer coalesced transaction records. The physical memory space required by the transaction file is reduced by the transaction record coalescing. The coalesced transaction records may be constructed so that they represent a logical result of applying each transaction record of a transaction record set in chronological order. Once the coalesced transaction records have been committed in the file system, the physical memory used by the original transaction records in the set may be reclaimed for further use (e.g., to store further transaction records) or may be otherwise removed from further use (e.g., when the physical memory is located in a block of memory in a flash-like memory device that has reached its maximum number of write and/or erase cycles). | 03-24-2011 |
| 20110072061 | OPTIMIZED STARTUP VERIFICATION OF FILE SYSTEM INTEGRITY - A computer system that may be used in implementing a transaction based file system is disclosed. The computer system includes a processor, random access memory that may be accessible by the processor, and a persistent data storage device that is likewise accessible by the processor. The computer system also may include file system software. The file system software may be executed by the processor and operates to manage the file data and the file system structure of the files stored on the persistent data storage device. Additionally, the file system software may maintain a transaction file that includes a plurality of transaction records. Each of the transaction records has a header section and a data section. The header section of each transaction record may include one or more fields that are designated to store information corresponding to a file transaction that is represented by the transaction record. If the operation of the file system software is interrupted, the file system software may resume its execution using a startup process in which a reconstructed file system may be generated in the random access memory. During system restart, the startup process may skip verification of the data section of a transaction record when the transaction record meets one or more predetermined criterion. For example, the startup process may make a distinction between transaction records merely affecting file data versus transaction records that affect the metadata of the file system. As transactions are found during the startup process, the file system software may identify whether a transaction impacts file data or metadata. Since only the metadata is required to ensure that the file system is in a consistent state after startup, the transaction records relating to metadata may be selected as the only subset of transaction records that are subject to complete verification. Verification of other transaction records may, for example, be limited to a check of the information contained in the header section of each remaining transaction record. | 03-24-2011 |
| 20110078219 | FILESYSTEM HAVING A FILENAME CACHE - A system comprising a processor, a data storage device that is accessible by the processor, and filesystem software that is executable by the processor to organize files on the data storage device are provided. The filesystem software is executable to maintain a filename cache having variable size filename entries. The filename entries may include a filename header section and a name section storing an entire filename of a corresponding file. | 03-31-2011 |
