A system and method for supporting Product Lifecycle Management over a distributed service network topology that connects a hierarchy of functional domains, each domain having a service ontology and one or more service composition schemas defined by the service ontology. Each service composition schema models a business process in its domain. Descriptions of services provided to each domain are published to a service repository by providers of the services, in conformity with one of the service composition schemas. There is a business process proxy provided by the service provider for each service description, which encapsulates for public access the internal processes of the service provider. The invention makes use of an event messaging protocol that enables service collaboration and ad-hoc workflow composition. Each business process is implemented by an ad-hoc workflow comprised of one or more tasks connected by one or more business rules. For each business process there is a business flow manager that dynamically composes ad-hoc workflow prior to execution and dynamically modifies the ad-hoc workflow as the business process executes. The business flow manager uses backward-chain inferencing and then forward-chain inferencing to generate the ad-hoc workflows, based on user identification of a target task. The business flow manager is able to stop execution of the workflow and regenerate a workflow for remaining tasks in response to events received over the network from service providers, and is also able to detect conflicts in the workflows at composition time and at execution time.

In one embodiment of the present invention a convolution engine configures a parallel processing pipeline to perform multi-convolution operations. More specifically, the convolution engine configures the parallel processing pipeline to independently generate and process individual image tiles. In operation, for each image tile, the pipeline calculates source locations included in an input image batch. Notably, the source locations reflect the contribution of the image tile to an output tile of an output matrix—the result of the multi-convolution operation. Subsequently, the pipeline copies data from the source locations to the image tile. Similarly, the pipeline copies data from a filter stack to a filter tile. The pipeline then performs matrix multiplication operations between the image tile and the filter tile to generate data included in the corresponding output tile. To optimize both on-chip memory usage and execution time, the pipeline creates each image tile in on-chip memory as-needed.

An arrangement which jointly exploits an agent component installed in a server-side portion of client-server architecture for emulating requests of actual clients of the client-server architecture and measuring a server execution time indicative of a time elapsed between reception of an emulated end-user request at a server component and generation of a result of said emulated end-user request at said server component; information stored in a server log file about a hit end to end response time, i.e., the time elapsed between the instant in which the end-user sends a request to the server component and the instant in which result of the request reaches the end-user. From the server execution time and the hit response time, the delay due to the network connecting the server-side portion of the client-server architecture to a client-side portion may be determined. The network delay and the server execution time are then used for monitoring performance of the client-server architecture by distinguishing network related problems from server-related problems or even from client-related problems.

A methodology for a daisy-chained memory topology wherein, in addition to the prediction of the timing of receipt of a response from a memory module (DIMM), the memory controller can effectively predict when a command sent by it will be executed by the addressee DIMM. By programming DIMM-specific command delay in the DIMM's command delay unit, the command delay balancing methodology according to the present disclosure “normalizes” or “synchronizes” the execution of the command signal across all DIMMs in the memory channel. With such ability to predict command execution timing, the memory controller can efficiently control power profile of all the DRAM devices (or memory modules) on a daisy-chained memory channel. A separate DIMM-specific response delay unit in the DIMM may also be programmed to provide DIMM-specific delay compensation in the response path, further allowing the memory controller to accurately ascertain the timing of receipt of a response thereat, and, hence, to better manage further processing of the response.

Circuits and methods to achieve a buck-boost converter, capable to achieve a constant output voltage by pre-charging of an inductor if the input voltage is close to the output voltage has been achieved. The prior art problem of output voltage variations occurring while the input voltage is close to the output voltage is avoided.
