Power consumption is an important factor in chip design. The fundamental design decisions drawn during early design space exploration at electronic system level (ESL) have a large impact on the power consumption. This requires to estimate power already at ESL, which is usually not possible using standard ESL component libraries due to missing power models.(More)
Diagnosing performance violations is one of the biggest challenges in transaction level modeling of systems. In this paper, we propose a methodology to localize root causes of latency or throughput violations. We present a concurrent pattern mining approach to infer frequent patterns from transaction traces to localize root causes. We apply three categories(More)
Hepatocellular carcinoma (HCC) cell lines are useful in vitro models for the study of primary HCCs. Because cell lines acquire additional mutations in culture, it is important to understand to what extent HCC cell lines retain the genetic landscapes of primary HCCs. Most HCC cell lines were established during the last century, precluding comparison between(More)
Complex many-core architectures are seen as the solution to tackle the computational workloads of the next years. To find the best trade-off between power and performance, different processor architectures have to be considered and evaluated in a thorough and power-aware design space exploration. This is highly facilitated by electronic system level (ESL)(More)
Hereditary tyrosinemia type I (HT1) is caused by a deficiency in the enzyme fumarylacetoacetate hydrolase (Fah). Fah-deficient mice and pigs are phenotypically analogous to human HT1, but do not recapitulate all the chronic features of the human disorder, especially liver fibrosis and cirrhosis. Rats as an important model organism for biomedical research(More)
Early design space exploration at Electronic System Level (ESL) can be done either using untimed functional models, timed functional models or performance models, which use random or zero data instead of the actual data. In order to be applicable to the two latter types, ESL power estimation approaches often rely only on sub-block activity information. This(More)
