International Conference on Reconfigurable Computing and FPGAs (ReConFig)

作者： Plumbridge, Gary Audsley, Neil C. Univ York Dept Comp Sci York YO10 5DD N Yorkshire England

FPGAs enable NoC architecture experimentation, although to be effective they need to be supported by tools and frameworks for construction of the NoC and effective software programming of the NoC. In this paper, we focus upon effective programming of the NoC using Java, complementing previous work which proposes the Blueshell framework for NoC generation for FPGAs. The approach taken is called Network-Chi, providing a number of key extensions to the Chi Java compiler. This includes provision of a networking API within Java giving a mesh based abstraction for network communication, allowing the programmer to send Java objects to other nodes without consideration for the underlying hardware topology or protocols;and a region-based memory management API that enables the definition of transient allocation contexts that discard all objects allocated within them when they reach the end of execution. Results show the approach taken to be efficient and effective.

The purpose of this paper is describing a semantics-driven approach to the automatic segmentation of song lyrics. The proposed algorithm takes into account the basic formatting commonly in use for lyrics on CD booklets and specialized Web sites, in order to extract basic semantic information, such as the organization in lines and sections. Then the algorithm applies simple rules to reconstruct lyrics structure, supporting tolerance margins as regards possible errors and encoding variants. The output is a sequence of sections labelled according to the similarity of their contents. The resulting segmenter is publicly available as a set of methods exposed via a Web application programming interface (API).

When APIs evolve, clients make corresponding changes to their applications to utilize new or updated APIs. Despite the benefits of new or updated APIs, developers are often slow to adopt the new APIs. As a first step toward understanding the impact of API evolution on software ecosystems, we conduct an in-depth case study of the co-evolution behavior of Android API and dependent applications using the version history data found in github. Our study confirms that Android is evolving fast at a rate of 115 API updates per month on average. Client adoption, however, is not catching up with the pace of API evolution. About 28% of API references in client applications are outdated with a median lagging time of 16 months. 22% of outdated API usages eventually upgrade to use newer API versions, but the propagation time is about 14 months, much slower than the average API release interval (3 months). Fast evolving APIs are used more by clients than slow evolving APIs but the average time taken to adopt new versions is longer for fast evolving APIs. Further, API usage adaptation code is more defect prone than the one without API usage adaptation. This may indicate that developers avoid API instability.

Birds of a Feather: Vamana Bhatta Bana's Hamsasandesa and Its Intertexts

引用

JOURNAL OF THE AMERICAN ORIENTAL SOCIETY 2013年第3期133卷 495-526页

作者： Bronner, Yigal Hebrew Univ Jerusalem IL-91905 Jerusalem Israel

Courier poetry is perhaps the richest and most vital literary genre of premodern South Asia, with hundreds of poems in a great variety of languages. But other than dubbing these poems "imitations" of Kalidasa's classical model, existing scholarship offers very little explanation of why this should be the case: why poets repeatedly turned to this literary form, exactly how they engaged with existing precedents, and what, if anything, was new in these many poems. In hopes of raising and beginning to answer such questions, this essay closely examines one such work, the Hamsasandesa of Vamana Bhatta Bana (fl. ca. 1400), and its close correspondence with two important intertexts. Kalidasa's Meghasandesa and Vedanta Desika's Hawasandesa. I argue that Vamana Bhatta Bana's work is an intricate mosaic that is put together from pieces both absences and presences that are taken from both these poems and that make sense only if we are familiar with their sources, and that this mosaic is nonetheless a surprisingly new and independent statement. On the basis of this analysis, I go on to suggest that novelty in the genre is partly made possible (and manifest) precisely through dense engagement with the vocabulary, figures of speech, situations, and other building blocks of the intertexts, a practice that often results in a heightened mode of density.

This paper introduces the OpenCV-FFI software package, which exposes datatypes and functions from the OpenCV computer vision library into the Ruby programming language. OpenCV-FFI uses the foreign function interface (FFI) to produce a Ruby API which mirrors the OpenCV C API;further layers of complexity are then built on that core API. Example code and benchmarking results show the effectiveness of using OpenCV-FFI for scripting OpenCV code within Ruby, as well as demonstrating the pitfalls of incautious use of Ruby iteration. Finally, there is a discussion of the relative advantages and disadvantages of the FFI-based approach versus a bespoke extension library written in Ruby-C or the use of an automatic wrapper generation packages (e. g., SWIG).

The Optimized Neuro Genetic Fast Estimator (ONGFE) is a software tool that allows for embedding system, subsystem, and component failure detection, identification, and prognostics (FDI&P) capability by using Intelligent Software Elements (ISE) based upon Artificial Neural Networks (ANN). With an application programming Interface (API), highly innovative algorithms are compiled for efficient distributed intelligence instantiation within embedded systems. The original design had the purpose of providing a real time kernel to deploy health monitoring functions for Condition Based Maintenance (CBM) and Real Time Monitoring (RTM) systems in a broad variety of applications (such as aerospace, structural, and widely distributed support systems). The ONGFE contains embedded fast and on-line training for designing ANNs to perform several high performance FDI&P functions. A key advantage of this technology is an optimization block based upon pseudogenetic algorithms which compensate for effects due to initial weight values and local minimums without the computational burden of genetic algorithms. The ONGFE also provides a synchronization block for communication with secondary diagnostic modules. The algorithms are designed for a distributed, scalar, and modular deployment. Based on this technology, a scheme for conducting sensor data validation has been embedded in Smart Sensors.

Aperture is an open, adaptable and extensible Web 2.0 visualization framework, designed to produce visualizations for analysts and decision makers in any common web browser. Aperture utilizes a novel layer based approach to visualization assembly, and a data mapping API that simplifies the process of adaptable transformation of data and analytic results into visual forms and properties. This common visual layer and data mapping API, combined with core elements such as contextually derivable color palettes, layout and symbol ontology services is designed to enable highly creative and expressive visual analytics, rapidly and with less effort. This paper introduces the Aperture framework, describing key features of the programming API and reference implementation, presents example use cases, and proposes an approach for measuring technical performance metrics for software development, and operational performance metrics for visualization support of analysis and decision making.

This paper describes a graphical and interactive software tool to support embedded systems engineering with highly integrated microcontrollers such as the ColdFire MCF54418. Such products have many input/output interfaces that share chip pins, hence not all possible combinations of active interfaces are feasible due to pin conflicts. To address challenges stemming from such conflicts, the software tool described in this paper provides early decision support for selection and subsequent hardware configuration of interfaces. An XML input file describes pins and interfaces of a microcontroller. From this information, the software tool generates an interactive graphical representation for a designer to interactively explore interfaces and pins, to visualize interface conflicts due to shared pins, and to incrementally develop conflict-free interface combinations. More importantly, the tool provides higher-level automated decision support with integer linear programming to solve an optimization problem and conclusively determine whether there exists a feasible conflict-free selection for given specifications on desired types and numbers of interfaces. Finally, for general-purpose input/output, the tool also has a more specialized mode that enables a user to indicate application-specific grouping and direction of pins. From this information, the tool automatically tailors an application programming interface in C code.

application programming interfaces (API) are exposed to developers in order to reuse software libraries. API directives are natural-language statements in API documentation that make developers aware of constraints and guidelines related to the usage of an API. This paper presents the design and the results of an empirical study on the directives of API documentation of object-oriented libraries. Its main contribution is to propose and extensively discuss a taxonomy of 23 kinds of API directives.
