this paper considers the automatic generation of parallelized fast-Fourier-transform (FFT) logic for field-programmable gate-array (FPGA) chips. A custom software tool has been created to generate VHDL logic descriptions for parallelized radix-4 FFT architectures using decimation-infrequency (DIF). these architectures accept N simultaneously-provided fixed-point complex-valued input samples every cycle for applicationsthat demand high throughput. Two approaches are described for generating the product terms in complex multiplications involving twiddle constants: standard single-cycle multiplication, and multi-cycle shift-and-add multiplication. Synthesis results are reported for parallelized FFT implementations of different sizes targeting low-cost Cyclone III chips and high-end Stratix III and IV chips from Altera. the shift-and-add approach for constant multiplication is shown to consume more logic resources, but provide a higher maximum clock frequency.
In this work, we present an FPGA hardware implementation for a phylogenetic tree reconstruction with maximum parsimony algorithm. We base our approach on a particular stochastic local search algorithm that uses the In...

this paper presents a graphene field effect transistor (GFET) nanosensor that, with a solid gate provided by a high-κ dielectric, allows analyte detection in liquid media at low gate voltages. the gate is embedded within the sensor and thus is isolated from a sample solution, offering a high level of integration and miniaturization and eliminating errors caused by the liquid disturbance, desirable for both in vitro and in vivo applications. We demonstrate that the GFET nanosensor can be used to measure pH changes in a range of 5.3-9.3. Based on the experimental observations and quantitative analysis, the charging of an electrical double layer capacitor is found to be the major mechanism of pH sensing.
In classical FPGA, LUTs and DFFs are pre-packed into BLEs and then BLEs are grouped into logic blocks. We propose a novel logic block architecture with fast combinational paths between LUTs, called pattern-based logic...
