Comparative study of DSL tools.

An increasingly wide range of tools based on different approaches are being used to implement Domain Specific Languages (DSLs), yet there is little agreement as to which approach is, or approaches are, the most appropriate for any given problem. We believe this can in large part be explained by the lack of understanding within the DSL community. In this paper we aim to increase the understanding of the relative strengths and weaknesses of three approaches by implementing a common DSL case study. In addition, we present a comparative study of the three approaches

A C++-embedded Domain-Specific Language for programming the MORA soft processor array

MORA is a novel platform for high-level FPGA programming of streaming vector and matrix operations, aimed at multimedia applications. It consists of soft array of pipelined low-complexity SIMD processors-in-memory (PIM). We present a Domain-Specific Language (DSL) for high-level programming of the MORA soft processor array. The DSL is embedded in C++, providing designers with a familiar language framework and the ability to compile designs using a standard compiler for functional testing before generating the FPGA bitstream using the MORA toolchain. The paper discusses the MORA-C++ DSL and the compilation route into the assembly for the MORA machine and provides examples to illustrate the programming model and performance

The Nature, Timing and Impact of Broadband Policies: a Panel Analysis of 30 OECD Countries

We empirically investigate the impact of a vast array of public policies on wireline broadband penetration through a novel and unique dataset covering 30 OECD countries, over 1995-2010. We find that while both supply and demand-side policies have a positive effect on broadband penetration, their relative impact depends on the actual stage of broadband diffusion. When an advanced stage is reached, only demand-side policies appear to generate a positive and increasing effect. Moreover, both technological and market competition play a positive role, and the effect of the latter shows a non-linear path along the stage of market development. Finally, the relative weight of the service sector in the national economy reveals to be crucial for broadband penetration. Our analysis provides new insights into the policy debate and in particular on the rationale of a selective policy design for broadband penetration and, in perspective, for the rollout of next-generation networks.telecommunications policies, broadband penetration, infrastructure investments

Virtual Collaborative R&D Teams in Malaysia Manufacturing SMEs

This paper presents the results of empirical research conducted during March to September 2009. The study focused on the influence of virtual research and development (R&D) teams within Malaysian manufacturing small and medium sized enterprises (SMEs). The specific objective of the study is better understanding of the application of collaborative technologies in business, to find the effective factors to assist SMEs to remain competitive in the future. The paper stresses to find an answer for a question “Is there any relationship between company size, Internet connection facility and virtuality?”. The survey data shows SMEs are now technologically capable of performing the virtual collaborative team, but the infrastructure usage is less. SMEs now have the necessary technology to begin the implementation process of collaboration tools to reduce research and development (R&D) time, costs and increase productivity. So, the manager of R&D should take the potentials of virtual teams into account

Low-Cost Broadband Connections: A Key Factor for SME Virtual Organizations

In an open global market, SMEs are facing new challenges while trying to compete with large worldwide corporations. The forming of innovative alliances, known as virtual organizations (VO), is one of the most interesting proposals to achieve competitiveness and exploit strategic advantages. However, besides the obvious positive potential of innovative actions like VOs, there are several drawbacks, especially when SMEs are involved in such projects. VOs have very high needs for IT and communications; in fact they rely so much on them that the forming of a VO is only possible with the development of an extensive information and communication infrastructure. A lot of innovating management, re-forming and re-structuring is involved in joining several independent companies into a new virtual schema and several cultural, economical and legislative problems must also be overcome. In this paper we focus on the technological needs, and in particular, the need for an organization-wide data sharing and communication network. The high cost involved with the investments necessary in IT and communications technology make the effort harder for SMEs, even if it was to be assumed that they could manage the other important aspects of forming a VO. Along with the cost of computer equipment and specialized software, networking cost has until recently been a particularly prohibiting factor for SMEs even on the most advanced business sectors. A new term, the “virtual organization technology threshold†is introduced, defined as the minimum of IT and communication technologies necessary to form a “true†virtual organization, in its pure and functional form described and widely adopted by the scientific community. The investments needed for IT and communications to form a VO are analyzed and compared to the related investments of conventional SMEs in EU. The evolution in the cost, focused around the networking tools, is then examined to extract useful information about the feasibility of such specialized investments compared to the overall investment and turnovers of typical SMEs. We then argue that a recent development, the price drop and wide spread of broadband connections can act as a “key factor†that could make the difference in lowering the “threshold†and increasing the possibilities for SMEs to compete successfully by utilizing technological advantages and innovations that have until now considered to be more suitable for larger enterprises.
