— A great interest has been gained in recent years by a new error-correcting code technique, known as " turbo coding, " which has been proven to offer performance closer to the Shannon's limit than traditional concatenated codes. In this paper, several very large scale integration (VLSI) architectures suitable for turbo decoder implementation are proposed(More)

Please share with us how this access benefits you. Your story matters. Abstract—Molecular Quantum Dot Cellular Automata, also called mQCA, are among the most promising emerging(More)
—The increased leakage, yield inefficiency, process, power supply and temperature variations have significant after-effects on the performance of complex VLSI architectures especially if mapped on Ultra Deep Sub Micron (UDSM) technologies. In this paper we assess the technology trend based on three industrial technologies (90nm, 65nm and 45nm) using a state(More)
—The use of " turbo codes " has been proposed for several applications, including the development of wireless systems, where highly reliable transmission is required at very low signal-to-noise ratios (SNR). The problem of extracting the best coding gains from these kind of codes has been deeply investigated in the last years. Also the hardware(More)

Molecular nanoelectronics is attracting much attention, because of the possibility to add functionalities to silicon-based electronics by means of intrinsically nanoscale biological or organic materials. The contact point between active molecules and electrodes must present, besides nanoscale size, a very low resistance. To realize Metal-Molecule-Metal(More)
Very low bit error rate has become an important constraint in high performance communication systems that operate at very low signal to noise ratios: due to their impressive coding gains, turbo codes have been proposed for several applications, although they suffer a large decoding delay. This paper presents the design of a turbo decoder with high(More)
One of the most crucial high performance Systems-on-Chip design challenge is to front their power supply noise sufferance due to high frequencies, huge number of functional blocks and technology scaling down. Marking a difference from traditional post physical design static voltage drop analysis, a priori dynamic voltage drop evaluation is the focus of this(More)
— This paper proposes a novel decoder architecture for the brand-new image coding standard JPEG2000. Innovative technologies involved in JPEG2000 framework will lead to rapid development of new mobile multimedia applications. In this scenario a well known critical factor is that computational resources available on tetherless terminals are limited and(More)
