Abstract: A semiconductor die is described. This semiconductor die includes an electro-static discharge (ESD) device with a metal component coupled to an input-output (I/O) pad, and coupled to a ground voltage via a signal line. Moreover, adjacent edges of the metal component and the I/O pad are separated by a spacing that defines an ESD gap. When a field-emission or ionization current flows across the ESD gap, the metal component provides a discharge path to the ground voltage for transient ESD signals. Furthermore, the ESD gap is at least partially enclosed so that there is gas in the ESD gap.

Moreover, the given CM is configured to communicate optical signals with other CMs through an optical signal path using optical communication, and the optical signals are encoded using wavelength-division multiplexing (WDM).

Abstract: A thin-client device having an application program obtains a copy of an application update having an update barrier level via a network. The thin-client device receives a set of configuration parameters from a configuration server via the network and sets the barrier level value to a value specified by the set of configuration parameters. Alternatively, the thin-client device retrieves a default barrier level value stored in the thin-client device. If the set of configuration parameters does not specify a barrier level value, the barrier level value is set to the default barrier level value. The thin-client device compares the update barrier level to a barrier level value corresponding to a minimum application version necessary to maintain support for a critical feature. If the update barrier level is greater than or equal to the barrier level value, the thin-client device updates its application program.

Abstract: Embodiments of a method for assembling a multi-chip module (MCM) are described. During this method, a fluid that includes coupling elements is applied to a surface of a base plate in the MCM. Then, at least some of the coupling elements are positioned into negative features on the surface of the base plate using fluidic assembly. Note that a given coupling element selects a given negative feature using chemical-based selection and/or geometry-based selection. Next, the fluid and excess coupling elements (which reside in regions outside of the negative features on the surface) are removed.

Abstract: Techniques for handling dependency conditions, including evil twin conditions, are disclosed herein. An instruction may designate a source register comprising two portions. The source register may be a double-precision register and its two portions may be single-precision portions, each specified as destinations by two other single-precision instructions. Execution of these two single-precision instructions, especially on a register renaming machine, may result in the appropriate values for the two portions of the source register being stored in different physical locations, which can complicate execution of an instruction stream. In response to detecting a potential dependency, one or more instructions may be inserted in an instruction stream to enable the appropriate values to be stored within one physical double precision register, eliminating an actual or potential evil twin dependency.

Abstract: A resource analyzer selects a resource (e.g., document) from a grouping of resources. The grouping of resources can be any type of social tagging system used for information retrieval. The selected resource has an assigned uncontrolled tag and an assigned controlled tag. The controlled tag is a term derived from a controlled vocabulary of terms. Having selected the resource for analyzing, the resource analyzer identifies a first set of resources in the grouping of resources having also been assigned a same value as the uncontrolled tag as the selected resource. Similarly, the resource analyzer identifies a second set of resources in the grouping of resources having also been assigned a same value as the controlled tag. With this information, the resource analyzer then produces a comparison result indicative of a similarity between the first set of resources and the second set of resources.

Abstract: Methods and apparatus are provided for simultaneously supporting multiple hosts with a single communication port; each host may host multiple functions. The input/output device comprises multiple buffers; each buffer stores packets for one host, but can be dynamically reallocated to a different host. Multiple buffers may simultaneously support the same host and all of its functions. After a packet is received and classified, it is stored in at least one buffer, along with control information for processing the packet upon egress from the buffer. Egress managers for each buffer extract packets and transfer them to destination host/functions, by speculatively moving the packets forward even while DMA engines perform their processing to facilitate their transfer.

In one embodiment, the target device is a mobile phone that provides sensor data from an integrated physical sensor to a development computer executing mobile phone software within the development environment using the same API's within the development environment as used on the embedded device.

Abstract: A method for queuing thread update buffers to enhance garbage collection. The method includes providing a global update buffer queue and a global array with slots for storing pointers to filled update buffers. The method includes with an application thread writing to the update buffer and, when filled, attempting to write the pointer for the update buffer to the global array. The array slot may be selected randomly or by use of a hash function. When the writing fails due to a non-null slot, the method includes operating the application thread to add the filled update buffer to the global update buffer queue. The method includes, with a garbage collector thread, inspecting the global array for non-null entries and, upon locating a pointer, claiming the filled update buffer. The method includes using the garbage collector thread to claim and process buffers added to the global update buffer queue.

Abstract: Methods and apparatus are provided for simultaneously supporting multiple hosts with a single communication port; each host may host multiple functions. The input/output device comprises multiple buffers; each buffer stores packets for one host, but can be dynamically reallocated to a different host. Multiple buffers may simultaneously support the same host and all of its functions. After a packet is received and classified, it is distributed to buffer ingress managers. Within a set of ingress managers serving one buffer, each manager corresponds to one function of the buffer's corresponding host, and is programmed with criteria for identifying packets desired by that function. One copy of the packet is stored in a buffer if at least one of the buffer's ingress managers accepts it, along with control information for processing the packet upon egress from the buffer. Egress managers for each buffer extract packets and transfer them to destination host/functions.

Abstract: A system including a first physical network interface card (NIC) include a number of rings, where at least one of the rings is an active ring. The system further includes a host, operatively connected to the first NIC, and including Media Access Control (MAC) layer. The MAC layer is configured to obtain a power management policy, obtain a load associated with the active ring, determine, using the power management policy and the load, that the state associated with at least one of the rings must be changed, and change, in response to the determining, the state of at least one of the of rings.

Abstract: One embodiment of the present invention provides a system that characterizes content in object code. During operation, the system receives the source code of a program. The system also receives one or more pieces of object code of the program, or creates one or more pieces of object code from the source code. Next, the system identifies a construct in the object code. The system then determines whether the construct is physically present in the source code. If the construct is not physically present, the system determines whether the construct is logically present in the source code, wherein a construct is logically present if it is required by the programming language. If so, the system sets a construct flag to indicate that the construct is “synthesized.” However, if not, the system sets the construct flag to indicate that the construct is “synthetic.” Finally, the construct flag is made available to a reflective API.

Abstract: A computing system includes a first virtual machine associated with a memory region readable by the first virtual machine, and a first private memory region. A data object is created by the first virtual machine in the sharable memory region, readable and writeable by the first virtual machine and a second virtual machine. A mapping is established between the first virtual machine and a particular area of the shareable memory region. The computing system includes the second virtual machine associated with a second private memory region, and a reference to the particular area of the shareable memory region. The mapping enables both the first virtual machine and second virtual machine to read and write second data in the shareable memory region without creating a copy of the second data in the first and second private memory regions.

Abstract: A method for migrating files including receiving, from a client, a file system (FS) operation request for a target FS, making a first determination that migration for a source FS is not complete, making a second determination that the FS operation request specifies a directory and that a directory level attribute for the directory on the target FS specifies that the directory is un-migrated. In response to the first and second determination, creating, using the meta-data for content in the directory, a directory entry for a file in the directory on the target FS, where the directory entry for the file is associated with a file level attribute that specifies the file is un-migrated, adding an unique identification (UID) for the file to a pending list, adding the UID for the directory to a removed list, and servicing, after the creating, the first FS operation request using target FS.
