Abstract: A bolster plate apparatus, used to secure a semiconductor device intermediate a printed circuit board and a heat sink apparatus, includes either an indentation or an open aperture into which a radio frequency absorptive material may be disposed. The absorptive material may be a ferrite material specifically selected to absorb frequencies in the range of the second to fourth harmonic of the processor clock signal frequency. The type of the ferrite material implanted in the bolster plate is selected to maximize the absorption of radio frequency energy, particularly that emitted at the pad vias on the underside of the printed circuit board, without affecting the signal integrity of the other pad connections. The shape of the cutout or aperture is also defined by the arrangement of RF emitting pads on the underside of the printed circuit board.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide for exchanging messages directly between a client and a selected server regardless of the use of a load balancer. The client generates a message to bypass performing load balancing functionality at the load balancer, and sends the message to the load balancer. The load balancing functionality is bypassed and the message is sent directly to the selected server by the load balancer.

Abstract: System and method for representing and rate the trustworthiness of peers as providers of content and data (codats) relevant to the peers' interests. In one embodiment, trust may be propagated through transaction pipes (paths) along which codats located in a search for codats relevant to an area of interest may be accessed by the requestor. In some embodiments, the trust a peer has in another peer as a provider of codats may be a function of the trust values of the provider peer and all other peers on a path. If there are multiple paths, trust in the provider peer may be an average of the trust values for all the paths. Trust in a provider peer may be used to determine confidence in codats provided by the peer. Embodiments may provide mechanisms for feeding back trust information to the providing peer and for propagating trust information to other peers.

Abstract: Dual match line circuits having race condition improvements. A dual match line circuit may include precharge logic configured to precharge each of a hit match line, a miss match line and an evaluate node to an asserted state, where a coupling device couples the hit and miss match lines to the evaluate node. The miss match line may discharge through a number of load devices that may be activated by respective miss signals. A positive feedback circuit coupled to the miss match line may accelerate its discharge. The hit match line may be additionally coupled to discharge through a discharge path. The hit and miss match lines may be electrically isolated from one another, such that when any of the respective miss signals is asserted, current from the hit match line does not discharge through the miss match line.

Abstract: A kernel device file system publication system for dynamically enumerating and configuring an instance of a device in the kernel device tree upon request by a user level application. The kernel device file system logically arranges system level devices in a hierarchical tree-like topology defining devices as nodes of a device tree to allow for a top-down access. The top-down access allows devices connecting to the computer system to be configured based on the physical path of the device. This process starts at a bus nexus and drives device configuration down the device tree. The bus configuration interfaces permit each nexus in the device tree hierarchy to participate in the device lookup and readdirs operations performed by the device file system. The device file system path operations are performed as an iterative sequence of bus configure operations, whereby each nexus controls the enumeration and configuration of that nexus' children.

Abstract: An analog debugging block of an integrated circuit includes a multiplexor, a buffer, and a voltage-controlled oscillator. An analog voltage signal-of-interest is selectively passed through the multiplexor to the buffer. The buffer outputs an analog control voltage dependent on the selected analog voltage signal-of-interest. The analog control voltage serves as an input to the voltage-controlled oscillator and is used to control a frequency of a digital output signal generated from the voltage-controlled oscillator. The digital output signal from the voltage-controlled oscillator is driven off-chip, whereupon a frequency of the digital output signal is determined and compared against a collection of known frequencies that correspond to particular known voltages of the analog voltage signal-of-interest, thereby resulting in a determination of the value of the selected analog voltage signal-of-interest.

Abstract: In a set of registers, each individually addressable by register operations using a corresponding register identification, at least one register of the set of registers is an extended register having multiple storage locations. Values stored in the multiple storage locations are accessed, for example, according to the order in which they have been stored. Less than all of the multiple storage locations are accessible by a register operation at a given time. Older versions of software that do not recognize extended registers identify the extended register as having only one storage location. An extended register can be, for example, a stack register, a queue register, or a mixed register and values stored in the multiple storage locations are read and stored according to the characteristics of the register.

Abstract: One embodiment of the invention provides a method for simulating the operation of a system. The method includes providing a fault tree representation of the system. The fault tree defines a set of problems that may occur in the system, and specifies propagations in the system whereby a problem may create one or more errors that may in turn be detected by error detectors to produce corresponding error reports. The fault tree representation allows the presence of a problem in the system to be simulated, and the set of error reports resulting from the simulated problem to be determined. This simulation can be repeated for different problems to compare the sets of error reports potentially produced by the different problems.

Next, the system applies the personalized rules to e-mail messages received for the user at the e-mail server. This involves applying actions specified in the personalized rules to the e-mail messages. Next, the system disconnects from the e-mail server so that the connection does not have to be maintained.

Abstract: A fabric driver on a host system connected to a fabric may include an API for an administration application to query and obtain a list of devices connected to a fabric host adapter port(s). The fabric driver may execute this query and obtain the list of devices by querying a fabric name server. One or more direct attach devices may also be discovered. For direct attach devices, like private loop topologies, operating system device nodes may be created during driver attach. However, for fabric topologies the fabric driver provides a list of devices visible through the fabric host adapter port by querying the fabric name server and supplies this list to the administration application in response to the administration application's request. A user may then select devices from this list to be onlined. A dynamic persistent repository may be maintained of devices onlined using this on-demand node creation process.

The hit and miss match lines may be electrically isolated from one another, such that when any of the respective miss signals is asserted, current from the hit match line does not discharge through the miss match line.

Abstract: A graphical computing system comprising a control unit and a set of edge processing units. The control unit (a) receives a surface primitive, (b) transfers edge specifying information for each edge of the surface primitive to a corresponding one of the edge processing units, and (c) transfers a horizontal address CX and a vertical address CY of a current pixel to the edge processing units. Each of the edge processing units computes trimming information for the current pixel with respect to the corresponding edge using the horizontal address CX and vertical address CY. The trimming information specifies a portion of the corresponding edge which intersects the current pixel. The control unit collects the trimming information from the edge processing units and transmits an output packet including the addresses CX and CY of the current pixel along with the collected trimming information.
