This paper describes a framework and tools for automating the production of designs which can be partially recon gured at run time. The tools include: (i) a partial evaluator, which produces con guration les for a given design, where the number of con gurations can be minimised by a process known as compile-time sequencing; (ii) an incremental con guration calculator, which takes the output of ...

In this paper, the possibility of using a silicon waveguide based microring resonator as a nonlinear all-optical switch is described under low power operation through a two-photon absorption effect. All-optical multiplexer/demultiplexer scheme based on two cascaded microring resonators has been proposed and described. The proposed circuits require smaller number of ring resonators and a single ...

Square root operation is hard to implement on FPGAs because of the complexity of the algorithms. In this paper, we present a non-restoring square root algorithm and two very simple single precision floating point square root implementations based on the algorithm on FPGAs. One is low-cost iterative implementation that uses a traditional adder/subtractor. The operation latency is 25 clock cycles...

Floating point arithmetic is widely used in many areas especially scientific computation and signal processing. The main objective of this paper is to reduce the power consumption and to increase the speed of execution and the implementation of floating point multiplier using sequential processing on the reconfigurable hardwareFloating Point (FP) addition, subtraction and multiplication are wid...

Multiple constant multiplication (MCM) scheme is widely used for implementing transposed direct-form FIR filters. While the research focus of MCM has been on more effective common subexpression elimination, the optimization of addertrees, which sum up the computed sub-expressions for each coefficient, is largely omitted. In this paper, we have identified the resource minimization problem in the...

Reversible circuit designing is the area where researchers are focussing more and more for the generation of low loss digital system designs. Researchers are using the concept of Reversible Logic in many areas such as Nanotechnology, low loss computing, optical computing, low power CMOS design etc. Here we have proposed a novel design approach for a 2-bit binary Arithmetic Logic Unit (ALU) usin...

The control of biochemical processes is a major goal in systems and synthetic biology. Current approaches are based on ad-hoc designs, whereas a general and modular framework would be highly desirable, in order to exploit the well-assessed methods of control theory. A well-known problem when dealing with complex biosystems is represented by the retroactivity effect, which can significantly modi...
