A real-time object detection and classification system using FPGA developed for high-speed asymmetric time-stretched optical microscopy (ATOM) framework is presented. Due to the massive amount of data generated by optical frontend, storing the raw data for offline post-processing is slow and impractical for the targeted single cell analysis applications. The proposed FPGA solution eliminates the need...
Asymmetric-Detection Time-Stretch Optical Microscopy (ATOM) is a recently emerged technology that provides ultra-fast cell imaging with a frame rate up to MHz — orders-of-magnitude higher than any classical imaging systems. However, existing measuring instruments are unable to fully exploit the capability of ATOM. For example, the volume of imaging data-set of ATOM quickly increases beyond the capacity...
<?Pub Dtl?>This paper presents two architectures for floating point (FP) adders, which operates in multi-mode configuration with multi-precision support. First architecture (named QPdDP) works in dual-mode which can operates either for quadruple precision or two-parallel double precision. The second architecture (named QPdDPqSP) works in tri-mode which is able to compute either of a quadruple...
This paper presents a configurable dual-mode architecture for floating point (F.P.) adder. The architecture(named as QPdDP) works in dual-mode which can operates either for quadruple precision or dual (two-parallel) double precision. The architecture follows the standard state-of-the-art flow for floating point adder. It is aimed for the computation of normal as well as sub-normal operands, along...
Many scientific applications take a very long time to execute on general purpose processors. Speedups can be obtained by using specialized hardware in conjunction with the processors. FPGA based accelerators are known to be effective for reducing the execution time of many scientific applications. Since FPGAs are configurable, they can be customized to implement a variety of processing elements as...
Modern FPGAs consist of a number of Hard Embedded Blocks (HEBs) like BRAMs, DSPs, PCI controllers, etc. for performing specialized operations/functions. This helps in developing efficient architectures for accelerating compute intensive kernels. Computational genomics is a fairly recent domain which helps in the understanding of the biological properties of an organism with applications in medicine,...
Next generation sequencing technologies produce large amounts of data at very low cost. They produce short reads of DNA fragments. These fragments have many overlaps, lots of repeats and may also include sequencing errors. The assembly process involves merging these sequences to form the original sequences. In recent years many software programs have been developed for this purpose. All of them take...
Three dimensional Fast Fourier Transform (3D-FFT) is popularly used in many scientific applications in various domains like image processing, bioinformatics and molecular dynamics. Typically 3D-FFT computation takes significant part of the execution time of these applications. In order to speedup these applications, it becomes necessary to accelerate 3D-FFT computation. 3D-FFT can be accelerated using...
