Abstract: An invention is disclosed managing the replicated and migration capable state for an enterprise Java bean (EJB) application. The invention includes executing a Java application on a server that includes an entity bean. In addition, a replicated state manager is executed that includes program instructions for managing an in-memory state of the Java application, and program instructions for replicating the in-memory state of the Java application to a replicated state server. The replicated state server can be a memory replicated state server, or a disk replicated state server. To facilitate application state management, embodiments of the present invention store states of the entity beans objects using state objects, which are updated in response to changes in the state of the application. Hence, the embodiments of the present invention define a logical separation between the application and the state objects.

Abstract: Architectures that enable different types of security devices to operate interchangeably in very large network environments for authentication and metered access to services are described. The system relies on a lease-based access to the network services. The leasing model supports a smart card type payment for services allowing for payments to be automatically forwarded from the smart card type device to the service whenever a service is leased. To lease a service, the requesting service must first be authenticated using devices like cellular phones, smart cards, Personal Data Assistants, or similar devices that have processing and memory capabilities and in some instances, wireless communication capabilities. Services may enter or exit the environment at will. Devices and services in this environment have public certificates that are used for authentication. Services may customize access to its products to make them available only to desired services.

Abstract: In one of the many embodiments disclosed herein, a method for dispatching read and write requests to a memory is disclosed which includes queuing at least one write request in a write queue and queuing an incoming read request in a read queue. The method also includes comparing the read request with at least one write request in the write queue to detect a matching write request, and if there is a matching write request, storing a write queue index of the matching write request as a first entry in an ordering queue. The method further includes dispatching the at least one write request to the memory in response to the first ordering queue entry.

Abstract: Mechanisms and techniques operate in a computerized device to enable or disable speculative execution of instructions such as reordering of load and store instructions a multiprocessing computerized device. The mechanisms and techniques provide a speculative execution controller that can detect a multiaccess memory condition between the first and second processors, such as concurrent access to shared data pages via page table entries. This can be done by monitoring page table entry accesses by other processors. The speculative execution controller sets a value of a speculation indicator in the memory system based on the multiaccess memory condition. If the value of the speculation indicator indicates that speculative execution of instructions is allowed in the computerized device, the speculative execution controller allows speculative execution of instructions in at least one of the first and second processors in the computerized device.

Abstract: A computer system including a first repeater and a second repeater that is coupled to the first repeater. The computer system also includes a third repeater that is coupled to the first repeater. The first repeater contains a first arbiter that arbitrates transactions between the first repeater and the second repeater and also arbitrates transactions between the first repeater and the third repeater. The second repeater receives transactions from the first repeater and contains a second arbiter that predicts receipt of transactions from the first repeater to the second repeater.

Abstract: In a synchronous clocked full-rail differential logic circuit with single-rail logic and shut-off the complementary logic function of the prior art is replaced by a single transistor appropriately sized to provide the complementary output. Consequently, the synchronous clocked full-rail differential logic circuits with single-rail logic and shut-off of the invention are smaller, less complex and are capable of operating efficiently under heavy load conditions without the increased size and the significant reduction in speed associated with prior art full-rail differential logic circuits. The addition of the shut-off device provides a full-rail differential logic circuit with shut-off that does not experience the “dip” experienced by prior art full-rail differential logic circuits and is therefore more power efficient and is more resistant to noise than prior art full-rail differential logic circuits.

Abstract: A method and system for processing instant messenger operations dependent upon presence state information in an instant messaging system. In one embodiment, the method may include receiving an instant messaging operation directed to a given user, where the given user is not offline; determining a presence state of an instant messenger in response to receiving the instant messaging operation, where the presence state corresponds to the given user; and selectively processing the instant messaging operation dependent upon the presence state in response to the determination. In another embodiment, the method may include storing an instant messaging operation associated with a given presence state of an instant messenger, where the given presence state corresponds to a given user; detecting a transition to the given presence state subsequent to storing the operation; and performing the instant messaging operation in response to the detection.

Abstract: A method and system for presence state assignment based on schedule information in an instant messenger system. In one embodiment, the method may include storing schedule information corresponding to a given user, where the schedule information is indicative of an activity status of the given user at a given time. The method may further include querying the schedule information, and if a current presence state of an instant messenger does not correspond to the activity status indicated by the schedule information, assigning a different presence state that corresponds to the activity status in response to the querying, where the current presence state and the different presence state each correspond to the given user.

Abstract: A SSTL memory interface pre-driver stage that uses a voltage regulator to generate a ‘virtual’ ground reference voltage is provided. The ‘virtual’ ground voltage reference, being greater than a zero volt ground voltage, allows low voltage transistors to be used, thereby improving interface performance and decreasing system power consumption. The pre-driver stage uses a biasing circuit to bias the voltage regulator, formed by a transistor arranged in a source follower configuration, to generate the ‘virtual’ ground reference voltage off which a voltage translator stage of the pre-driver stage operates to generate an output of the pre-driver stage.

Abstract: A system for querying a database. Query strings comprising queries from application program are loaded from a text file into a query lookups table. The application then utilizes a database interface query function to access the queries in the lookups table. The query function uses the query name provided by the application to locate the corresponding query string in the lookups table. The query function then performs parameter substitution on the query string and sends the query to the database. The query results are then retrieved, formatted, and sent to the querying application. The present invention allows an application program to access data stored on databases organized by various database management systems which employ different query formats. Although the databases organize the data differently, the same content may be extracted by the present system. Changes to the database queries take place outside the application code in a simple text file that is loaded by the querying application.

Abstract: An Ethernet architecture is provided for connecting a computer system or other network entity to a dedicated Ethernet network medium. The network interface enables the transmission and receipt of data by striping individual Ethernet frames across a plurality of logical channels and may thus operate at substantially the sum of the individual channel rates. Each channel may be conveyed by a separate conductor (e.g., in a bundle) or the channels may be carried simultaneously on a shared medium (e.g., an electrical or optical conductor that employs a form of multiplexing). On a sending station, a distributor within the sender's network interface receives Ethernet frames (e.g., from a MAC) and distributes frame bytes in a round-robin fashion on the plurality of channels. Each “mini-frame” is separately framed and encoded for transmission across its channel. On a receiving station, the receiver's network interface includes a collector for collecting the multiple mini-frames (e.g.

Abstract: A caching mechanism for a virtual persistent heap. A feature of a virtual persistent heap is the method used to cache portions of the virtual persistent heap into the physical heap. The caching mechanism may be effective with small consumer and appliance devices that typically have a small amount of memory and that may be using flash devices as persistent storage. In the caching mechanism, the virtual persistent heap may be divided into cache lines. A cache line is the smallest amount of virtual persistent heap space that can be loaded or flushed at one time. Caching in and caching out operations are used to load cache lines into the heap or to flush dirty cache lines into the store. Different cache line sizes may be used for different regions of the heap. Translation between a virtual persistent heap address and the heap may be simplified by the caching mechanism.

Abstract: A display device executing a network messaging protocol and capable of receiving display requests from multiple network devices communicating with the display device over an Internet Protocol (IP) based network is disclosed. The network priority messaging protocol executed by the display device enables the display device to efficiently display messages received from multiple network devices. The protocol enables the display device to prioritize among incoming messages from different network devices and to prioritize among incoming multiple messages from a single device. The protocol executed by the display device further enables the display device to receive display characteristics encoded as part of a message from a network device.

Abstract: Methods and apparatus for managing execution of an application according to an application lifecycle. The application lifecycle is managed by an application manager through a set of commands that enable the application manager to cause the application to enter one of a plurality of states. In addition, the application can communicate with the application manager to indicate that the application cannot change its state as the application manager has requested or to request that the application manager change the state of the application to a particular state.

Abstract: In one embodiment, a computer system includes a first component configured to output data on a bus in response to a request for data from a second component. The data output by the first component may include both the requested data and unrequested data, and the unrequested data may have an unpredictable value. A controller coupled to the bus may be configured to replace the unrequested data with data that has a predictable value. A signature analysis register included in the second component is configured to capture the requested data and the predictable data output by the controller. Thus, the signature captured in the second component may be predictable, despite the unpredictable data output by the first component.
