The high performance potential of an FPGA is not fully exploited if a design suffers a memory bottleneck. Therefore, a memory hierarchy is needed to reuse data in on-chip buffer memories and minimize the number of accesses to off-chip memory. Buffer memories not only hide the external memory latency, but can also be used to remap data and augment the on-chip bandwidth through parallel access of...

The high potential performance of FPGAs cannot be exploited if a design suffers a memory bottleneck. Therefore, a memory hierarchy is needed to reuse data in on-chip memories and minimize the number of accesses to off-chip memory. Buffer memories not only hide the external memory latency, but can also be used to remap data and augment the on-chip bandwidth through parallel access of multiple bu...

Between April 2005 and March 2009, the e-Services Integration Group at the University of Hull undertook two Joint Information Systems Committee (JISC)-funded projects, RepoMMan and REMAP. The RepoMMan tool developed a browser-based interface through which a user could interact with a private digital repository space to support the development of their works-in-progress. It went on to look at th...

Over the last decade, various algorithms for localizing extra-pulmonary vein (PV) AF drivers/sources (focal or rotational activity) have been studied. Validating these mapping systems is confounded by lack of ground truth, typically manifesting as poor map reproducibility. Short optical studies, it remains difficult to prove that identified drivers are true drivers, so other criteria needed but...

BACKGROUND Polyploidization is a major evolutionary process in plants where hybridization and chromosome doubling induce enormous genomic stress and can generate genetic and epigenetic modifications. However, proper evaluation of DNA sequence restructuring events and the precise characterization of sequences involved are still sparse. METHODOLOGY/PRINCIPAL FINDINGS Inter Retrotransposons Ampl...

The problem of two-dimensional tracer advection on the sphere is extremely important in modeling of geophysical fluids and has been tackled using a variety of approaches. A class of popular approaches for tracer advection include ‘incremental remap’ or cell-integrated semi-Lagrangian-type schemes. These schemes achieve high-order accuracy without the need for multistage integration in time, are...
