Appele Talk vs current Netwoork

AppleTalk is a network operating system designed to connect Apple computers. Its components are built on Macintosh operating systems. There are two main versions of AppleTalk depending on how many years in the past the network was implemented, Phase 1 and Phase 2. Phase 2 is the current installation as of about 2002.It designed and [...]

Efficient Integer DCT Architectures for HEVC

 ABSTRACT         We present area- and power-efficient architectures for the implementation of integer discrete cosine transform (DCT) of different lengths to be used in High Efficiency Video Coding (HEVC).We show that an efficient constant matrix multiplication scheme can be used to derive parallel architectures for 1-D integer DCT of different lengths. We [...]

Area-Delay-Power Efficient Fixed-Point LMS Adaptive Filter With Low Adaptation-Delay

ABSTRACT In this paper, we present an efficient architecture for the implementation of a delayed least mean square adaptive filter. For achieving lower adaptation-delay and area-delay-power efficient implementation, we use a novel partial product generator and propose a strategy for optimized balanced pipelining across the time-consuming combinational blocks of the structure. From synthesis results, we [...]

Data Encoding Techniques for Reducing Energy Consumption in Network-on-Chip

ABSTRACT As technology shrinks, the power dissipated by the links of a network-on-chip starts to compete with the power dissipated by the other elements of the communication subsystem, namely, the routers and the network interfaces. In this paper, we present a set of data encoding schemes aimed at reducing the power dissipated by the links [...]

Input Vector Monitoring Concurrent BIST Architecture Using SRAM Cells

ABSTRACT Input vector monitoring concurrent built-in self test (BIST) schemes perform testing during the normal operation of the circuit without imposing a need to set the circuit offline to perform the test. These schemes are evaluated based on the hardware overhead and the concurrent test latency (CTL), i.e., the time required for the test to [...]

Area–Delay–Power Efficient Carry-Select Adder

ABSTRACT                             In this paper, we made an analysis on the logic operations involved in conventional carry select adder (CSLA) and binary to excess-1 converter (BEC)-based CSLA to study the data-dependency and to identify redundant logic operations. We have eliminated all the redundant logic operations present in conventional CSLA and proposed a new logic [...]

Area-Delay Efficient Binary Adders in QCA

ABSTRACT As transistors decrease in size more and more of them can be accommodated in a single die, thus increasing chip computational capabilities. However, transistors cannot get much smaller than their current size. The quantum-dot cellular automata (QCA) approach represents one of the possible solutions in overcoming this physical limit, even though the design of [...]

Improved 8-Point Approximate DCT for Image and Video Compression Requiring Only 14 Additions

ABSTRACT: Video processing systems such as HEVC requiring low energy consumption needed for the multimedia market has lead to extensive development in fast algorithms for the efficient approximation of 2-D DCT transforms. The DCT is employed in a multitude of compression standards due to its remarkable energy compaction properties. Multiplier-free approximate DCT Transforms have been [...]

High-Throughput Multistandard Transform Core Supporting MPEG/H.264/VC-1 Using Common Sharing Distributed Arithmetic

ABSTRACT: This paper proposes a low-cost high-throughput multi standard transform (MST) core, which can support MPEG- 1/2/4 (8 × 8), H.264 (8 × 8, 4 × 4), and VC-1 (8 × 8, 8 × 4, 4×8, 4×4) transforms. Common sharing distributed arithmetic (CSDA) combines factor sharing and distributed arithmetic sharing techniques, efficiently reducing the number [...]

Stereo Vision Images Processing for Real-time Object Distance and Size Measurements

ABSTRACT        Human has the ability to roughly estimate the distance and size of an object because of the stereo vision of human’s eyes. In this project, we proposed to utilize stereo vision system to accurately measure the distance and size (height and width) of object in view. Object size identification is very useful in [...]
