In this paper, we present a first approach for array-level energy estimation during high-level synthesis when mapping piecewise regular algorithms onto massively parallel full size processor arrays. Innately, piecewise regular algorithms have some power consumption friendly properties, e.g., they may be mapped onto processor arrays with only local interconnect and memory. In addition to these p...

A known problem in the area of hardware/software codesign is the selection of the proper interface between the different parts of the design. This paper presents a technique which eases the selection by combining different synthesis techniques together with rapid prototyping. Application field of the technique is the design of communication systems where C and VHDL are generated from a specific...

There is now a good understanding of problems encountered in the design, implementation and use of a high-level language converter. These general issues are illustrated in terms of an account of the design and implementation of one particular converter, which converts programs from Pascal-SC (a Pascal dialect) to Ada. A specific aim of the presentation is to provide guidance for those contempla...

This paper presents a number of design concepts and ideas for a group spreadsheet. Unlike single user spreadsheets, these group spreadsheets should have speciic features to enhance group communication, and to maintain a shared context. Rather than presenting a single design, we discuss alternatives and general-izable issues because the speciic design can be very dependent upon the environment. ...

This paper reports the preliminary work on extending the concept of collection in 81/2. 81/2 is a declarative language that allows the functional definition of streams and collections [1, 2]. In this paper, we focus our interest on a high-level programming abstraction which extends the concept of collection in 81/2. The new construct is based on an algebra of index set, called shape, and an ext...

This paper addresses the problem of semantic analysis of paintings by automatic detection of the represented scene type. The solution comes as an incipient effort to fill the gap already stated in the literature between the low level computational analysis and the high level semantic dependent human analysis of paintings. Inspired by the way humans perceive art, we first decompose the image in ...
