Fast inference using FPGAs for DUNE data reconstruction

A Field Experiment for Coastal Dune Reconstruction

Coastal dunes, as a whole, represent a natural barrier between the sea and the land, playing a vital role in the coastal defense against the waves and tides. Compared to the use of hard, man-made structures, not only is it a less expensive method to counteract the coastal erosion problems, but it is also a method that has higher ecological and scenic values in the environmental management aspec...

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

Fast Regular Expression Mat hing using FPGAs

Fast evaluation of nonlinear functions using FPGAs

The paper presents a novel method of evaluating the square root function in FPGA. The method uses a linear approximation subsystem with a reduced size of a lookup table. The reduction in the size of the lookup table is twofold. Firstly, a simple linear approximation subsystem uses the lookup table only for the node points. Secondly, a concept of a variable step look-up table is introduced, wher...

Fast Local Scrubbing for FPGAs

Memory scrubbing is used to mitigate SEU on susceptible devices. In the case of FPGAs, configuration memory scrubbing is generally used in conjunction with triple modular redundancy (TMR) to increase the reliability of FPGA systems in space borne applications. Reported solutions require a subsystem able to read and write from the configuration memory and retrieve from a “safe storage” a golden ...
