FIFO (First In First Out) is a buffer that stores data in a way that data stored first comes out of the buffer first. Asynchronous FIFO is most widely used in the System-on-Chip (SoC) designs for data buffering and flow control. As the designs gets complex, the probability of occurrence of bugs increases. This necessitated ...

Information security is the most important issues in network communication in current days. Safe and sound data transfer become more essential and significant, as security is a major concern in the field of message transformation over internet in current years, cryptography and steganography are two significant areas of research that involve a number of applications. ...

In this paper, the authors describe the concept of adaptive noise cancelling, an alternative method of estimating signals corrupted by additive noise or interference. A desired signal corrupted by additive noise can often be recovered by an adaptive noise canceller using the Least Mean Squares (LMS) algorithm. This adaptive noise canceller is then useful for ...

Computer architecture researchers evaluate key areas such as pipelining, organization, instruction issue, branching, and exception handling when considering asynchronous and synchronous design and implementation trade-offs. Asynchronous or clockless designs are considered as an alternative to conventional synchronous digital system design. The major advantages of asynchronous are low power consumption, better modularity, higher robustness and higher ...

The phase vocoder is a tool used to perform time-stretching and pitch-shifting on recorded sounds. Voice morphing is the process of producing intermediate or hybrid voices between the utterances of two speakers. It can also be defined as the process of gradually transforming the voice of one speaker to that of another. Like image morphing, ...

Cloud computing is an internet based computing model that supports convenient, on-demand and pay-for-use model. In this computing, data owners host their data on cloud servers and clients can access the data from cloud servers. Due to the data outsourcing, efficient verification of the outsourced data becomes a formidable challenge for data security in Cloud ...

Swarm Intelligence (SI) is a type of artificial intelligence, based on the collective behavior of decentralized, self-organized systems. This paper presents a survey of applications of Glowworm Swarm Optimization (GSO) algorithms designed in the various fields. Glowworm Swarm Optimization (GSO) is a recent nature-inspired optimization algorithm that simulates the behavior of the lighting worms. GSO ...

Viterbi decoder is the dominant module to determining the power consumption of the system. High speed and low power design of Viterbi decoder with data rate1/2 and convolution encoding with a constraint length K Subscribe to the Innovation Insider Newsletter Catch up on the latest tech innovations that are changing the world, including IoT, 5G, ...

In this paper, an encryption technique using matrix based substitution and diffusion for fast image encoding is discussed. The cryptographic procedure manipulates a two dimensional array (matrix) for substitution and diffusion operations. The procedure facilitates fast conversion of plaintext and images into cipher text and cipher images. The paper describes the encryption procedure, discusses on ...

Most of the existing encryption algorithms are best suited for textual data and cannot directly be applied on images since image data have special features such as bulk capacity, high redundancy and high correlation among pixels that imposes special requirements on the encryption technique used. Therefore, image security has its own special requirements that lead ...
