Coarse-grained reconfigurable architectures aim to achieve both goals of high performance and flexibility. However, existing reconfigurable array architectures require many resources without considering the specific application domain. Functional resources that take long latency and/or large area can be pipelined and/or shared among the processing elements.(More)
Pharmaceuticals are manufactured and used for specific biological functions in veterinary and human medicine. Their detection in the environment and their bioactivity have resulted in concern for potential adverse effects on non-target species. Notwithstanding recent attention for their occurrence in the environment, there are significant research gaps for(More)
Interconnect delay should be considered together with computation delay during architectural synthesis in order to achieve timing closure in deep submicrometer technology. In this paper, we propose an architectural synthesis technique for <i>distributed-register architecture,</i> which separates interconnect delay for data transfer from component delay for(More)
We evaluated the occurrence of three antibiotics (roxithromycin, trimethoprim, and chloramphenicol) in surface water and effluents from several sewage treatment plants (STPs) on the Han River, Korea. In addition, standard acute toxicity tests were conducted using the microbe Vibrio fischeri, freshwater macroinvertebrates Daphnia magna and Moina macrocopa,(More)
Cartap and cypermethrin, which are among the most widely used pesticides in many countries, are considered safe because of their low mammalian toxicity and their low persistence in the environment. However, recent findings of endocrine-disrupting effects and developmental neurotoxicity have raised concerns about the potential ecological impacts of these(More)
To achieve fast verification of the software part of embedded system, we propose to run the target processor optimistically, which effectively reduces the synchronization overhead with other simulators. For the optimistic processor execution, we present a processor execution platform and state saving/restoration methods. We performed optimistic execution of(More)
In this paper, we propose a method for performance improvement of multi-processor systems cosimulation by reducing synchronization overhead between multiple simulators. To reduce the amount of simulator synchronization, we predict synchronization time points based on a static analysis of application software running on each processor. In the experiments(More)
We assessed the phototoxicity of several major sulfonamide antibiotics, i.e., sulfathiazole, sulfamethazine, and sulfamethoxazole, using acute 48 and 96 h Daphnia magna immobilization toxicity test under several indoor and outdoor lighting conditions. The lighting conditions were as follows: (1) fluorescent light only, (2) continuous irradiation with 15(More)
This paper presents a case study on fast prototyping of a wireless CDMA cellular phone system. We set up a fast prototyping flow which aims at reducing the coverification time. We captured executable specifications of the system with Ptolemy and Polis tools. We developed a prototyping board, a board debugger which provides in-circuit emulation functions,(More)
Pharmaceutical residues may have serious impacts on nontarget biological organisms in aquatic ecosystems, and have therefore precipitated numerous investigations worldwide. Many pharmaceutical compounds available on the market need to be prioritized based on their potential ecological and human health risks in order to develop sound management decisions. We(More)
