There are increasing concerns about possible malicious modifications of integrated circuits (ICs) used in critical applications. Such attacks are often referred to as hardware Trojans. While many techniques focus on hardware Trojan detection during IC testing, it is still possible for attacks to go undetected. Using a combination of new design techniques(More)
Chronic liver disease is a major public health problem worldwide. Liver fibrosis, a common feature of almost all causes of chronic liver disease, involves the accumulation of collagen, proteoglycans, and other macromolecules within the extracellular matrix. Fibrosis tends to progress, leading to hepatic dysfunction, portal hypertension, and ultimately(More)
Biotinidase deficiency is a metabolic disorder characterized by inability to recycle biotin with resultant delayed myelination. Clinical findings include seizures, ataxia, alopecia and dermatitis with atypical findings of myoclonic jerks, neuropathy and spastic paraparesis. Neuroradiological findings include cerebral atrophy, encephalopathy and widened(More)
We generate and provide miniature synthetic benchmark clones for modern workloads to solve two pre-silicon design challenges, namely: 1) huge simulation time (weeks to months) when using complete runs of modern workloads like SPEC CPU2006 having trillions of instructions on pre-silicon design models 2) unavailability of access to their specific target(More)
Prohibitive simulation time with pre-silicon design models and unavailability of proprietary target applications make microprocessor design very tedious. The framework proposed in this paper is the first attempt to automatically generate synthetic benchmark proxies for real world multithreaded applications. The framework includes metrics that characterize(More)
Current advancements in imaging technology, especially three-dimensional/four-dimensional ultrasound and contrast-enhanced imaging, have increased the diagnostic yield of adnexal masses. The benefit of ultrasound is the characterization of an adnexal mass, suggesting the probable etiology of the mass. Masses may be divided as solid, cystic, or complex. It(More)
To effectively design a computer system for the worst case power consumption scenario, system architects often use hand-crafted maximum power consuming benchmarks at the assembly language level. These stressmarks, also called power viruses, are very tedious to generate and require significant domain knowledge. In this paper, we propose SYMPO, an automatic(More)
The SPEC CPU2006 suite, released in Aug 2006 is the current industry-standard, CPUintensive benchmark suite, created from a collection of popular modern workloads. But, these workloads take machine weeks to months of time when fed to cycle accurate simulators and have widely varying behavior even over large scales of time [1]. It is to be noted that we do(More)
The practically attainable worst case power consumption for a computer system is a significant design parameter and it is a very tedious process to determine it by manually writing high power consuming code snippets called power viruses. Previous research efforts towards automating the power virus generation process are all limited to the single core(More)
MOTIVATION Recent advancements in sequencing technology have led to a drastic reduction in the cost of sequencing a genome. This has generated an unprecedented amount of genomic data that must be stored, processed and transmitted. To facilitate this effort, we propose a new lossy compressor for the quality values presented in genomic data files (e.g. FASTQ(More)
