The ability to build maps of indoor environments is extremely important for autonomous mobile robots. In this paper we introduce Voronoi random fields (VRFs), a novel technique for mapping the topological structure of indoor environments. Our maps describe environments in terms of their spatial layout along with information about the different places and(More)
Spatially-tiled architectures, such as Coarse-Grained Re-configurable Arrays (CGRAs), are powerful architectures for accelerating applications in the digital-signal processing, embedded, and scientific computing domains. In contrast to Field-Programmable Gate Arrays (FPGAs), another common accelerator, they typically time-multiplex their processing elements(More)
In this paper we present SPR, a new architecture-adaptive mapping tool for use with Coarse-Grained Reconfigurable Architectures (CGRAs). It combines a VLIW style scheduler and FPGA style placement and pipelined routing algorithms with novel mechanisms for integrating and adapting the algorithms to CGRAs. We introduce a latency padding technique that(More)
Coarse-grained reconfigurable architectures (CGRAs) have the potential to offer performance approaching an ASIC with the flexibility, within an application domain, similar to a digital signal processor. In the past, coarse-grained reconfigurable architectures have been encumbered by challenging programming models that are either too far removed from the(More)
To date, health effects of exposure to the September 11, 2001 disaster in New York City have been studied in specific groups, but no studies have estimated its impact across the different exposed populations. This report provides an overview of the World Trade Center Health Registry (WTCHR) enrollees, their exposures, and their respiratory and mental health(More)
Coprocessor accelerator architectures like FPGAs and GPUs are increasingly used in embedded systems because of their high performance on computation-heavy inner loops of a variety of applications. However, current languages and compilers for these archi-tectures make it challenging to efficiently implement kernels that have complex, input-dependent control(More)
In February of 2004, the New York City Department of Health and Mental Hygiene completed the integration of its childhood immunization and blood lead test registry databases, each containing over 2 million children. A modular approach was used to build a separate integrated system, called Master Child Index, to include all children in both the immunization(More)
