VLSI DESIGN OF ITERATIVE KARATSUBA MULTIPLIER AND ITS EVALUATION

by Syunji Yazaki
"... Multi-digit multiplication is widely used for various ap-plications in recent years, including numerical calculation, chaos arithmetic, primality testing. Systems with high per-formance and low energy consumption are demanded, es-pecially for image processing and communications with cryptography usi ..."

RESEARCH ARTICLE Multi-Contrast Imaging and Digital Refocusing on a Mobile Microscope with a Domed LED Array

by Zachary F. Phillips, Michael V. D'ambrosio, Lei Tian, Jared J. Rulison, S. Patel, Nitin Sadras, Aditya V. G, Neil A. Switz, Daniel A. Fletcher
"... We demonstrate the design and application of an add-on device for improving the diagnos-tic and research capabilities of CellScope—a low-cost, smartphone-based point-of-care mi-croscope. We replace the single LED illumination of the original CellScope with a programmable domed LED array. By leveragi ..."

. By leveraging recent advances in computational illumina-tion, this new device enables simultaneous multi-contrast imaging with brightfield, darkfield, and phase imaging modes. Further, we scan through illumination angles to capture lightfield datasets, which can be used to recover 3D intensity and phase images

Evaluation of Streams-C C-toFPGA Compiler: An Applications Perspective

by Jan Frigo, Dominique Lavenier - in Proc. of ACM/SIGDA International Symposium on Field-Programmable Gate Arrays (FPGA
"... software co-design The Streams-C compiler ([5]) synthesizes hardware cir-cuits for recongurable FPGA-based computers from par-allel C programs. The Streams-C language consists of a small number of libraries and intrinsic functions added to a synthesizable subset of C, and supports a communicating pr ..."

-tuples or tubes. Convolutions take the place of scalar multiplica-tion. This framework allows us to embed the 2-D data into a vector-space-like structure called a free module over a commutative ring. These free modules re-tain many properties of complex inner-product spaces, and we leverage that to provide

Augmented piano performance using a depth camera

by Qi Yang, Georg Essl - In Proc. NIME 2012 , 2012
"... We augment the piano keyboard with a 3D gesture space using Microsoft Kinect for sensing and top-down projec-tion for visual feedback. This interface provides multi-axial gesture controls to enable continuous adjustments to multi-ple acoustic parameters such as those on the typical digital synthesiz ..."
