Abstract: One embodiment of the present invention provides a system that generates code to perform anticipatory prefetching for data references. During operation, the system receives code to be executed on a computer system. Next, the system analyzes the code to identify data references to be prefetched. This analysis can involve: using a two-phase marking process in which blocks that are certain to execute are considered before other blocks; and analyzing complex array subscripts. Next, the system inserts prefetch instructions into the code in advance of the identified data references. This insertion can involve: dealing with non-constant or unknown stride values; moving prefetch instructions into preceding basic blocks; and issuing multiple prefetches for the same data reference.

Abstract: Various embodiments of systems and methods for performing accumulation operations on block operands are disclosed. In one embodiment, an apparatus may include a memory, a functional unit that performs an operation on block operands, and a cache accumulator. The cache accumulator is configured to provide a block operand to the functional unit and to store the block result generated by the functional unit. The cache accumulator is configured to provide the block operand to the functional unit in response to an instruction that uses an address in the memory to identify the block operand. Thus, the cache accumulator behaves as both a cache and an accumulator.

Abstract: Monitoring the health of a system module can be carried out during state transitioning, for example when starting or stopping a system module. A monitor module can be operationally connected to the system module. The system module can output a status signal for predetermined system status points during state transitioning. The monitor module can start a timer on detecting a first status signal and can reset the timer on detecting a subsequent status signal. The timer can indicate a failed transitioning of the system module in the event that the timer is not reset within a determined period of being reset.

Abstract: One embodiment of the invention provides a smart card having multiple applications installed thereon. One of the multiple applications is designated as a default application which is activated whenever the card is reset. The default application is required to implement a first operation to provide a canonically ordered listing of the multiple applications on the card. The default application may further implement a second operation to allow one of the multiple applications to be selected for activation via an index into the listing.

Abstract: One embodiment of the present invention provides a system that facilitates automatically using a predefined networking group, such as a peer-to-peer group as a context for an application. The system starts by executing the application on behalf of a peer. During execution of the application, the system determines if the peer is a member of a networking group, and if so, the system uses the networking group as a context for the application.

Abstract: System resources (e.g., objects or other resources) are managed to provide multiple levels of undo and/or support for delegation of updates on main-memory resident objects accessible by concurrent transactions. For example, a log associated with each transaction stores information regarding an update to an object when the object is locked in an update mode (e.g., a write mode) by the transaction. The transaction can be rolled back by restoring information from the log of the transaction to the object. If the transaction commits, then the log may be destroyed. If the transaction delegates to another transaction, the log of the transaction is also delegated. A record codelet can be automatically generated to perform the storing of information in the log, and a restore codelet can be automatically generated to undo updates by restoring information from the log to the updated objects. The codelets may be specific to each class of objects.

Abstract: An audio management apparatus manages simultaneous streams of packet-switched audio data for a network conference tool. The apparatus uses a receiver thread to receive packets input from different audio connection points, and a sender thread to send modified packets to the audio connection points. The apparatus uses a plurality of member objects, each associated with a different connection point, to modify the packets to create a custom mix of audio data for each connection point. A common mix, consisting of all of the packets input from all of the connection points, is also maintained, and is used by each of the member objects, along with the packets maintained by the member objects, to perform the desired mixing. The overall number of receiver threads and sender threads is independent of the number of member objects, thereby allowing the system to be highly scalable.
