Mobile Ad Hoc Networks (MANETs) have been an important research topic for the last years, playing a crucial role within the fast growing sector of mobile communications. At the same time, video applications over mobile devices are becoming widely used by nowadays mobile clients, where the quality in the transmission of such contents will determine the success of these applications in the future. Therefore,...
Although many efficient high-level algorithms have been proposed for the realization of Multiple Constant Multiplications (MCM) using the fewest number of addition and subtraction operations, they do not consider the low-level implementation issues that directly affect the area, delay, and power dissipation of the MCM design. In this paper, we initially present area efficient addition and subtraction...
This work presents a study about FPGA interconnections and evaluates their effects on voltage-mode binary and quaternary FPGA structures. FPGAs are widely used due to the fast time-to-market and reduced non-recurring engineering costs in comparison to ASIC designs. Interconnections play a crucial role in modern FPGAs, because they dominate delay, power and area. The use of multiple-valued logic allows...
Ubiquitous broadband Internet access is an important requirement to satisfy user demands and support a new set of real time services and applications. WiMAX, a broadband wireless access solution for wireless metropolitan area networks, covering large distances with high throughputs, is a promising technology for next generation networks. Nevertheless, for the successful deployment of WiMAX based solutions,...
We address the problem of optimizing logic-level sequential circuits for low power. We present a powerful sequential logic optimization method that is based on selectively precomputing the output logic values of the circuit one clock cycle before they are required, and using the precomputed values to reduce internal switching activity in the succeeding clock cycle. We present two different precomputation...
