Abstract: A method, system and computer program product for enabling a register file to recover from detection of a parity error. A first register file and a second register file are associated with a parallel file structure. When the parity error is detected, the system determines whether the first register file or second register file is associated with the parity error. The register file determined to have the parity error is associated with an offending register and a non-offending register is associated with the “good” register file. Subsequent to the detection of the parity error, the system executes a repair sequence, whereby the register file associated with the offending register receives data from the register file associated with the non-offending register. The offending register file recovers from the parity error with or without the use of a parity interrupt.

The supervisor computer is able to remotely control usage of the soft phone according to information provided by the UDP packets.

Abstract: A method and system that enables cross-border compliance with export restrictions of particular computer technology, including software loaded on a computing device. The computing device is loaded with software, and has a country location device, such as a low-end GPS device. The country location device (country locator) stores the present geographic location of the device in a location register. When the computing device is turned on or the software is activated for operation on the computing device, a security utility of the software compares the value in the register against a list of pre-established locations that are export-restricted. When the value matches (or falls within a range) of one of pre-established locations, the features of the software that are export restricted are automatically disabled.

Abstract: A processing unit includes a store-in lower level cache having reservation logic that determines presence or absence of a reservation and a processor core including a store-through upper level cache, an instruction execution unit, a load unit that, responsive to a hit in the upper level cache on a load-reserve operation generated through execution of a load-reserve instruction by the instruction execution unit, temporarily buffers a load target address of the load-reserve operation, and a flag indicating that the load-reserve operation bound to a value in the upper level cache. If a storage-modifying operation is received that conflicts with the load target address of the load-reserve operation, the processor core sets the flag to a particular state, and, responsive to execution of a store-conditional instruction, transmits an associated store-conditional operation to the lower level cache with a fail indication if the flag is set to the particular state.

Abstract: A technique of operating a communication device includes dividing a frequency band associated with a background noise signal into respective sub-bands. Respective individual level estimates for each of the respective sub-bands are then determined. A total level estimate for the background noise signal is determined. Finally, a comfort noise signal (whose characteristics are based on the respective individual level estimates and the total level estimate) is provided.

Abstract: An improved multi-layered ceramic package comprises: a plurality of signal layers, each having one or more signal lines; a plurality of vias, each providing one of a voltage (Vdd) power connection or a ground (Gnd) connection; at least one reference mesh layer adjacent to one or more signal layers; and a plurality of via-connected coplanar-type shield (VCS) lines, with a first VCS line extending on a first side of a first signal line within the plurality of signal layers and a second VCS line extending on a second opposing side of the first signal line. Each of the plurality of VCS lines interconnect with and extend past one or more vias that are located along the directional path in which the VCS lines runs. The placement of the VCS lines relative to the signal lines reduces coupling noise and controls impedance discontinuity in the ceramic package.

Abstract: A method of and system for managing a conference call among participants and a moderator provides a control mode in which only one participant can speak at time. All participants other than the speaker are muted. The system maintains a talk queue. When a participant requests to speak, the system places the participant in the talk queue. The system may announce to the moderator that the participant has registered to speak. The system may also announce to the moderator the participant's position in the talk queue. When a speaking participant relinquishes, or is preempted from, the speaking position, the system mutes the speaking participant. The system informs the participant at the top of the talk queue that it is his or her turn to speak and unmutes that participant, whereby that participant becomes the new speaking participant. The system removes the new speaking participant from the talk queue. The system may announce their respective positions to the other participants in the talk queue.

Abstract: A technique for communicating in a wireless communication system includes creating, using two distinct Alamouti codes, a power-scaled quasi-orthogonal space-time block code. The technique further includes transmitting, using a transmitter, the power-scaled quasi-orthogonal space-time block code over multiple antennas (e.g., three or four transmit antennas).

Abstract: A virtual machine manager (VMM) enables provisioning of services to multiple clients via a single data processing system configured as multiple virtual machines. The VMM performs several management functions, including: configuring/assigning each virtual machine (VM) for/to a specific, single client; scheduling the time and order for completing client services via the assigned client VM; instantiating a client VM at a scheduled time and triggering the execution of services tasks required for completing the specific client services on the client VM; monitoring and recording historical information about the actual completion times of services on a client VM; and updating a scheduling order for sequential instantiating of the multiple client VMs and corresponding client services, based on one or more of (i) pre-established time preferences, (ii) priority considerations, and (iii) historical data related to actual completion times of client services at a client VM.

Abstract: A flip-flop includes a functional latch and a retention latch. The functional latch is configured to maintain a logic state of the flip-flop in a power-up mode and the retention latch is configured to maintain the logic state of the flip-flop in a power-down mode. The retention latch is selectively coupled to the functional latch and the retention latch is configured to maintain the logic state in the power-down mode irrespective of a level of an associated clock signal when the power-down mode is entered. A clock pulse that clocks the flip-flop is derived from the associated clock signal.

Abstract: A method, system, and computer program product for creating and implementing file clones using reverse ditto references. A clone inode is created as a copy of an original inode. The clone inode and the original inode are indistinguishable to an end user. Each additional file clone created spawns a clone inode. An immutable clone-parent inode is created that contains the disk block addresses, while writable clones inode instead contain dittos linking the clone inode to data blocks referenced in the clone-parent inode. Data block address links in the original inode are moved to the new clone-parent inode and dittos replace the original data block address links in the original inode. When a clone file is updated, the new data is written to a new disk location and a corresponding ditto in the clone inode is replaced with a data block link address, keeping the data of the clone-parent inode intact.

Abstract: A processing unit includes a processor core and a cache memory coupled to the processor core. The cache memory includes a data array, a directory of the data array, error detection logic that sequentially detects a first, second and third correctable errors in the data array of the cache memory and provides indications of detection of the first, second and third correctable errors, and control circuitry that, responsive to the indication of the third correctable error and an indication that the first and second correctable errors occurred at too high a frequency, marks an entry of the data array containing a cache line having the third correctable error as deleted in the directory of the cache memory regardless of which entry of the data array contains a cache line having the second correctable error.

Abstract: In response to a data request of a first processing unit among a plurality of processing units, the first processing unit selects a victim cache line to be castout from the lower level cache of the first processing unit and selects the lower level cache of a second of the plurality of processing units as an intended destination of a lateral castout (LCO) command by randomized round-robin selection. The first processing unit issues on the interconnect fabric an LCO command identifying the victim cache line and the intended destination. In response to a coherence response to the LCO command indicating success of the LCO command, the first processing unit removes the victim cache line from its lower level cache, and the victim cache line is held in the lower level cache of one of the plurality of processing units other than the first processing unit.
