Connectors in distributed architecture play an important role. Software engineers meet more and more challenges of designing connectors. Particularly, in a distributed MVC architecture, there are many issues in the design of connectors such as: how to apply the architecture pattern to design of connector in distributed MVC system; how to make the connectors of MVC become loosely coupled. With the...
Recent advancement in 4th generation (4G) heterogeneous networking has opened the door for the deployment of femto-cells on a large scale. Deployment of femtocells in the existing macrocell networks and in 4G networks will significantly increase because femtocells offer increase coverage, capacity and user friendly mode of operations in both home and office environments. Therefore, these low power...
The current trend of digital convergence leads to the need of the video decoder that should support multiple video standards such as, H.264/AVC, JPEG, MPEG-2, VC-1, and AVS on a single platform. In this paper, we present a resource-shared architecture of multiple transforms to support all five video codecs. The architecture is based on a new multi-dimensional delta mapping. Here the Inverse Discrete...
A femtocell offers increased coverage and capacity in both home and office environments because these low power home based access points are going to change the landscape of mobile technology and the networking business in the coming years. Therefore, deployment of a femtocell in the existing macrocell networks and in 4th generation (4G) networks will significantly increase. The objective of this...
Side channel attacks have been considered as serious threats to certain public-key cryptosystems, such like RSA and elliptic curve system. For modular exponentiation for RSA and scalar multiplication for elliptic curve cryptosystems, Montgomery powering ladder has been shown to be a good choice for counter-measures against side-channel attacks. In this paper, two efficient architectures for modular...
This paper describes a new approach in designing communications between processes in a multi-threaded environment. This technique supports real-time performance and can be adapted for embedded operating systems. At present, Message-Passing is a widely used technique in designing Interprocess Communication Systems. This design may degrade performance of Realtime Systems. The present research introduces...
This paper reports on the efficient implementations of a reconfigurable architecture of discrete wavelet packet transform (DWPT) with three types of multipliers on a field-programmable gate array (FPGA). The multipliers include the FPGA's internal multipliers, lookup table (LUT) based multipliers, and partial product multipliers (PPMs). Using two filters, a high-pass filter and a low-pass filter,...
