A method and system for allowing clients to retrieve data from data sources that do not necessarily support the same protocols and formats as the clients. The clients issue service requests. A pre-processor responds to the requests by generating XML-structured request objects with unresolved links to the data sources that have information required by the clients. An XML processor resolves the links by issuing requests through one or more gateways. The gateways convert the responses received from the data sources into XML, which the XML processor uses to create XML composite response documents. A post-processor filters the XML response documents, and applies XSL stylesheets to transform the XML composite response documents into client-specific responses that conform to the format required by the clients. The client-specific responses are then sent to the clients.

An efficient method for compressing sampled analog signals in real time, without loss, or at a user-specified rate or distortion level, is described. The present invention is particularly effective for compressing and decompressing high-speed, bandlimited analog signals that are not appropriately or effectively compressed by prior art speech, audio, image, and video compression algorithms due to various limitations of such prior art compression solutions. The present invention's preprocessor apparatus measures one or more signal parameters and, under program control, appropriately modifies the preprocessor input signal to create one or more preprocessor output signals that are more effectively compressed by a follow-on compressor. In many instances, the follow-on compressor operates most effectively when its input signal is at baseband. The compressor creates a stream of compressed data tokens and compression control parameters that represent the original sampled input signal using fewer bits. The decompression subsystem uses a decompressor to decompress the stream of compressed data tokens and compression control parameters. After decompression, the decompressor output signal is processed by a post-processor, which reverses the operations of the preprocessor during compression, generating a postprocessed signal that exactly matches (during lossless compression) or approximates (during lossy compression) the original sampled input signal. Parallel processing implementations of both the compression and decompression subsystems are described that can operate at higher sampling rates when compared to the sampling rates of a single compression or decompression subsystem. In addition to providing the benefits of real-time compression and decompression to a new, general class of sampled data users who previously could not obtain benefits from compression, the present invention also enhances the performance of test and measurement equipment (oscilloscopes, signal generators, spectrum analyzers, logic analyzers, etc.), busses and networks carrying sampled data, and data converters (A / D and D / A converters).

A method instruments a function in an executable file so that the instrumented function calls a generic preprocessor prior to execution of the body of the function. After the preprocessor modifies the original function's incoming parameters, the body of the function itself is executed. Finally, execution is directed to a generic postprocessor prior to returning from the function. The postprocessor modifies the outgoing parameters and return value. In one implementation, the parameters of an instrumented function are described and packaged into a descriptor data structure. The descriptor data structure is passed to the generic preprocessor and postprocessor. A generic processor uses the descriptor to select changed behaviors based on the calling context.

A method and logical apparatus for switching between single-threaded and multi-threaded execution states within a simultaneous multi-threaded (SMT) processor provides a mechanism for switching between single-threaded and multi-threaded execution. The processor receives an instruction specifying a transition from a single-threaded to a multi-threaded mode or vice-versa and halts execution of all threads executing on the processor. Internal control logic controls a sequence of events that ends instruction prefetching, dispatch of new instructions, interrupt processing and maintenance operations and waits for operation of the processor to complete for instructions that are in process. Then, the logic determines one or more threads to start in conformity with a thread enable state specifying the enable state of multiple threads and reallocates various resources, dividing them between threads if multiple threads are specified for further execution (multi-threaded mode) or allocating substantially all of the resources to a single thread if further execution is specified as single-threaded mode. The processor then starts execution of the remaining enabled threads.

In one embodiment, an LDPC decoder performs a targeted bit adjustment method to recover a valid codeword after the decoder has failed. In a first stage, a post processor initializes the decoder by saturating LLR values output by the decoder during the last (i.e., failed) iteration to a relatively small value. Then, two-bit trials are performed, wherein LLR values corresponding to two bits of the codeword are adjusted in each trial. Decoding is performed with the adjusted values, and if the number of unsatisfied check nodes exceeds a specified threshold, then a second stage is performed. The post processor initializes the decoder by saturating the LLR values output by the decoder during the last (i.e., failed) iteration of the first stage to a relatively small value. The second stage then performs single-bit adjustment trials, wherein one LLR value corresponding to one bit of the codeword is adjusted in each trial.
