Practical Cellular Dividers
Absfmcf-The parallel division algorithms discussed in this paper may be classified among modified higher radix nonrestor-ing on-line division methods, where redundant representations are extensively utilized to speed up the operation. The network realizations of these algorithms are cellular, or even systolic with exclusively local control; they have size (area) and time both O (n) , where n is...
متن کاملSuperharmonic Injection-Locked Frequency Dividers
Injection-locked oscillators (ILO’s) are investigated in a new theoretical approach. A first-order differential equation is derived for the noise dynamics of ILO’s. A single-ended injection-locked frequency divider (SILFD) is designed in a 0.5m CMOS technology operating at 1.8 GHz with more than 190 MHz locking range while consuming 3 mW of power. A differential injection-locked frequency divid...
متن کاملPower Aware Dividers in FPGA
This paper surveys different implementations of dividers on FPGA technology. A special attention is paid on ATP (area-time-power) trade-offs between restoring, non-restoring, and SRT dividers algorithms for different operand widths, remainder representations, and radices. Main results show that SRT radix-2 present the best ATP figure. In combinational implementation, an important power improvem...
متن کاملPractical Cellular Performance Bounds via Shotgun Cellular Systems
This paper considers two-dimensional interference-limited cellular radio systems. It introduces the shotgun cellular system that places base stations randomly and assigns channels randomly. Such systems are shown to provide lower bounds to cellular performance that are easy to compute, independent of shadow fading, and apply to a number of design scenarios. Traditional hexagonal systems provide...
متن کاملPractical Fault Tolerant 2D Cellular Automata
Cellular automata often suffer from a level of brittleness that makes them susceptible to even the smallest unexpected environmental changes. We propose a method of converting CAs into more robust structures called meta-CAs that utilize cell redundancy along with added rules to correct errors and reproduce the functionality of the original CA. We show that the use of these meta-CAs can greatly ...
