Abstract: A system and method for using a management interface such as Portable Management Interface (PMI) in a thread-safe and efficient manner. A secondary scheduler receives PMI management requests from multi-threaded manager applications in a thread-safe manner, such as through a lock. The secondary scheduler monitors the flow of PMI-related requests into PMI to ensure that, at any point in time, only one management request (e.g., callback function) is running on the PMI thread. When a request in the secondary queue is ready for scheduling with the primary scheduler, the secondary scheduler then accesses the primary scheduler in a thread-safe manner, such as through a lock, to send the request to the primary scheduler. The management requests are dispatched from the primary scheduler and executed on managed objects though a Management Information Server.

In one embodiment, multiple pluggable components may be configured by the BCU in batch mode.

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.

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.

The instruction decode unit uses the working copy of the current window pointer to handle the window management instruction.

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: 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: 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 method and apparatus for modulating a beam of charged particles is described in which a beam of charged particles is produced by a particle source and a varying electric field is induced within an ultra-small resonant structure. The beam of charged particles is modulated by the interaction of the varying electric field with the beam of charged particles.

Abstract: We describe an ultra-small structure that produces visible light of varying frequency, from a single metallic layer. In one example, a row of metallic posts are etched or plated on a substrate according to a particular geometry. When a charged particle beam passed close by the row of posts, the posts and cavities between them cooperate to resonate and produce radiation in the visible spectrum (or even higher). A plurality of such rows of different geometries can be etched or plated from a single metal layer such that the charged particle beam will yield different visible light frequencies (i.e., different colors) using different ones of the rows.

Abstract: A system for selecting routing information from a routing table describing alternative routes between end nodes. The routing table represents a set of minimum cost, deadlock-free routes between end nodes. The selected routing information is included in forwarding tables, and sent to networking devices in the network. The selected routing information is optimized for at least one network performance metric, such as overall network capacity or fault tolerance. Capacity optimization is obtained by selecting from alternative routes stored within the routing table such that the standard deviation of the number of routes flowing over each link in the network is minimized. Fault tolerance optimization is achieved by selecting from the alternative routes stored in the routing table such that the selected route for a given end node pair has a “failover” route with a maximum number of dissimilar links from the selected route.

Abstract: A method and apparatus are provided for controlling the power consumption of a semiconductor device such as a CPU or other form of processor that is operable to process a sequence of instructions. The device includes a monitor for checking the power consumption of the device, in order to detect any significant change in power consumption (which can cause problems for the power supply circuitry). In order to mitigate such change, one or more dummy instructions are inserted into the sequence of instructions. The dummy instructions do not affect the logical processing, but are selected in order to limit the change in power consumption. Thus if the change in power consumption represents an increase, then dummy instructions are selected that do not require much current. Conversely, if the change in power consumption represents a decrease, then dummy instructions are selected that draw a relatively large amount of current.
