Abstract: A hardware unit for parsing an XML document includes embedded logic or circuitry for accessing the document, decoding it to change a character set, validating individual characters of the document, extracting tokens, maintaining a symbol table and generating binary token headers to describe the document's structure and convey the document's data to an application. Tokenization, the process of identifying tokens and generating token headers, may be controlled by a finite state machine that recognizes XML delimiters in the document's markup and activates state transitions based on the current state and the recognized delimiter. The parser unit may be implemented within a hardware XML accelerator that includes a processor, a DMA engine, a cryptographic engine, memory (e.g., for storing a document, maintaining a symbol table) and various interfaces (e.g., network, memory, bus).

Abstract: One embodiment of the present invention provides a system that handles instruction fetch requests that return out-of-order at an IFU of a processor. During operation, the system sends a request to obtain a cache line to an instruction cache, wherein the request can be serviced and the cache line can be sent to a fetch buffer before a preceding cache line for a preceding request has returned from the instruction cache. In response to the request, the system receives the cache line from the instruction cache. Next, the system determines whether the cache line was returned out-of-order with respect to the preceding cache line. If so, the system performs an action to handle the out-of-order return.

Abstract: One embodiment of the present invention provides a system that uses a zooming effect to provide additional display space to manage applications. In one mode of operation, the system presents an image of a computer desktop to the user on a display device. When the system receives a request from a user to provide additional display space in a display device for application management purposes, the system decreases the size of the computer desktop in the display device to provide an extended display area. The system then facilitates application management by displaying items useful for application management in this extended display area. By providing the extended display area, the system allows the user to access such items easily and efficiently without losing the context of the computer desktop.

Abstract: A method and apparatus for performing virtualized parsing of an XML document. A document is divided into multiple segments, which may correspond to separate packets containing portions of the document, disk blocks, memory pages, etc. For each segment, a processor operating within an XML accelerator initiates parsing by identifying to a hardware parsing unit the document segment, a symbol table for the document and a location for storing state information regarding the parsing. Each segment is parsed in sequence, and the state information of the parsing is stored after each segment is completed, for retrieval when the next segment is to be parsed.

The system then characterizes the response of the component to vibrations generated by the computer system based on the measured response of the component to vibrations in the frequency range and the measured vibrations in the frequency range at the location.

Abstract: An apparatus or method for testing of a SOC processor device may minimize interference that is caused by interfacing a comparatively low-speed testing device with the high-speed processor during testing. Implementations may gate the input clock signal at the clock input to each domain of the SOC processor device rather than at the output of the PLL clock. The gating of the clock signal to each domain may then be controlled by clock stop signals generated by the testing device and sent to the individual domains of the processor device. Gating the clock signal at the domain may provide a more natural state for the circuit during testing as well as allow the test control unit to test the different domains of the SOC device individually.

Abstract: One embodiment of the present invention provides a system that maintains keys using limited storage space on a computing device, such as a smart card. During operation, the system receives a request at the computing device to perform an operation involving a key.
