One or more techniques and/or systems are provided for creating socially authored, or community authored, summaries of documents and/or for navigating a forum comprising such summaries. In one embodiment, at least some of the summaries are generated automatically when a document is written and/or discovered (e.g., by a web crawler), for example. In another embodiment, the documents are created by users of the forum. A plurality of summaries of a document may be created (e.g., by different users), and users can provide feedback, such as comments or ratings, that may assist other users in identifying which summary or summaries better describe the document. Moreover, the users can navigate the forum and retrieve summaries by browsing categories (and subcategories) to identify a topic of interest and/or by performing a search based upon user inputted search term(s).

A multi-tasking operating system and method updates PCI address values in an extension register to ensure that various threads utilize the correct values when accessing peripheral PCI devices. When application program threads require access to a PCI device, the operating system writes the high order bits of the PCI device address to two places: (1) the extension register of the PCI host bridge to allow immediate addressing of the PCI device, and (2) separate memory locations associated with the threads. When a context switch occurs from a first thread to a second thread, the operating system retrieves the stored value from the memory location associated with the second thread and writes the value to the extension register. In this manner, when the second thread requires access to its PCI device, the proper address value is already located in the extension register.

A content addressable memory (CAM) architecture comprises two components, a small, fast on-chip cache memory that stores data that is likely needed in the immediate future, and an off-chip main memory in normal RAM. The CAM allows data to be stored with an associated tag that is of any size and identifies the data. Via tags, waves of data are launched into a machine's computational hardware and re-associated with related tags upon return. Tags may be generated so that related data values have adjacent storage locations, facilitating fast retrieval. Typically, the CAM emits only complete operand sets. By using tags to identify unique operand sets, computations can be allowed to proceed out of order, and be recollected later for further processing. This allows greater computational speed via multiple parallel processing units that compute large sets of operand sets, or by opportunistically fetching and executing operand sets as they become available.

An intrusion detection system disclosed herein includes a detector circuit that measures a change in value of impedance of an interconnection circuitry. A decoder coupled to the detector decodes the measured value of the change in the impedance of the interconnection circuitry to determine existence of an abnormal condition. In an example implementation of the intrusion detection system, the change in the value of the impedance of the interconnection circuitry is represented by a change in the phase delay on the interconnection circuitry. An implementation of the intrusion detection circuit terminates communication using the interconnection circuitry upon detection of the abnormal condition. The intrusion detection system is further configured to interpret the abnormal condition as a communication signal to the interconnection circuitry.

A power regulating system and method are provided for regulating power in a portable computing device. The portable computing device includes microprocessing and radio communication capabilities. The power regulating system utilizes a number of power states to regulate the device's internal power source voltage. The power regulating system operates to selectively control and regulate the device's internal power consumption based on the power state of the device, and thereby extends the useful life of the device by prolonging the battery life of the device.

A computer system includes a centerplane formed by a printed circuit board. The centerplane has a plurality of Desktop PCI electrical connectors on one side and a plurality of CompactPCI electrical connectors on the other. This allows the use of both Desktop and CompactPCI boards in a signal bus board, without requiring complex bridging circuits. In addition, this allows additional boards to be used without extending the length of the PCI bus.

A Random Access Memory (RAM) based Content Addressable Memory (CAM) architecture is disclosed. In an implementation, the CAM architecture includes a CAM data structure associated with a RAM to store one or more tags and associated data values. Each of the tags includes one or more bit fields which are utilized as an index for referencing a look-up table. One or more look-up tables may be realized for supporting memory operations facilitating efficient transfer modes available in the RAM.

The use of a configuration-based execution model in conjunction with a content addressable memory (CAM) architecture provides a mechanism that enables performance of a number of computing concepts, including conditional execution, (e.g., If-Then statements and while loops), function calls and recursion. If-then and while loops are implemented by using a CAM feature that emits only complete operand sets from the CAM for processing; different seed operands are generated for different conditional evaluation results, and that seed operand is matched with computed data to for an if-then branch or upon exiting a while loop. As a result, downstream operators retrieve only completed operands. Function calls and recursion are handled by using a return tag as an operand along with function parameter data into the input tag space of a function. A recursive function is split into two halves, a pre-recursive half and a post-recursive half that executes after pre-recursive calls.
