Research ArticleOpen accessPhrase in the titleDesign and Implementation of an Efficient Software Communications Architecture Core Framework for a Digital Signal Processors PlatformWael A. Murtada, Mohamed M. Zahra, Magdi Fikri et al.Problem statement: The Software Communications Architecture (SCA) was developed to improve software reuse and interoperability in Software Defined Radios (SDR). There had been performance concerns since its conception. Arguably, the majority of the problems and inefficiencies associated with the SCA can be attributed to the assumption of modular distributed platforms relying on General Purpose Processors (GPPs) to perform all signal … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 7,495 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGate Replacement Technique for Reducing Leakage Current in Wallace Tree MultiplierNaveen Raman, ThanushkodiLeakage power has become more significant in the power dissipation of today’s CMOS circuits. This affects the portable battery operated devices directly. The multipliers are the main key for designing an energy efficient processor, where the multiplier design decides the digital signal processors efficiency. In this study gate replacement technique is used to reduce the leakage power in 4×4 Wallace … …Journal of Computer Science, Vol. 9, Issue 2 · 30 Mar 2013 · 6,763 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Quasi Delay Insensitive Reduced Stack Pre-Charged Half Buffer based High Speed Adder using pipeline templates for Asynchronous CircuitsD. Jayanthi, M. RajaramProblem statement: Recent research in asynchronous design technique is making asynchronous circuits an increasingly practical alternative. These challenges include the increasing pressure for low power, the growing challenges of predicting the increasing impact of wire load and delay and the performance penalty associated with supporting communication between different clock domains Asynchronous is binary signals, but there is no common or … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jun 2012 · 7,078 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Software Agent for Speech Abiding SystemsR. Manoharan, K. Vivekanandan, V. SundaramProblem statement: In order to bring speech into the mainstream of business process an efficient digital signal processor is necessary. The Fast Fourier Transform (FFT) and the butter fly structure symmetry will enable the harwaring easier. With the DSP and software proposed, togetherly established by means of a system, named here as “Speech Abiding System (SAS)”, a software agent, which … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,744 accessesView PDF Cite
