Ibrahim, M. E. A., M. Rupp, and H. A. H. Fahmy, "{A Precise High-Level Power Consumption Model for Embedded Systems Software}", {EURASIP} Journal on Embedded Systems, vol. 2011, 2011. AbstractWebsite

The increasing demand for portable computing has elevated power consumption to be one of the most critical embedded systems design parameters. In this paper, we present a precise high-level power estimation methodology for the software loaded on a VLIW processor that is based on a functional level power model. The targeted processor of our approach is the TMS320C6416T DSP from Texas Instrument. We consider several important issues in our model such as the pipeline stall, inter-instructions effect and cache misses. The contributions are the following. First, a precise model to estimate the power consumption of the targeted DSP, while running a software algorithm is proposed. Second, we prove the validation and precision of our model on many typical algorithms applied in signal and image processing. Third, we further validate the precision of our model on a real application applied in the video processing field. The power consumption estimated by our model is compared to the physically measured power consumption, achieving a very low average absolute estimation error of 1.65% and a maximum absolute estimation error of only 3.3%.

Abstract

Breast cancer is a heterogeneous disease that encompasses several distinct entities with different biological characteristics and clinical behavior. Basal subtype is considered as a prognostically unfavorable subset. The purpose of this study is to compare the clinico-pathological characteristics and outcome of basal vs. luminal A subtype, as approximated by ER, PR, and HER-2. Sixty-four patients with basal breast cancer were matched for age, stage, and year of diagnosis with 64 patients having luminal A disease. Basal tumors were immunohistochemically defined by a lack of expression of estrogen receptor (ER), progesterone receptor (PR), and HER-2, while luminal A cancers were ER+ or PR+, and HER-2-. As compared with luminal A, basal subtype patients had significantly larger primary tumor size, higher percentage of grade III tumor, more tumor that showed lymphovascular invasion, less presence of non-invasive disease, and higher proportion of extranodal extension. There was no statistically significant difference in metastatic sites, pathology type, or in the axillary lymph nodal status. A few patients received neoadjuvant chemotherapy--13 and 9 patients in basal and luminal A groups, respectively). The complete pathological response was 20% and 14%, respectively (not significant). At a median follow-up of approximately 2 years, there was no statistically significant difference in the overall survival rate between basal and luminal A patients. Analysis of disease-free survival (DFS) for stage I-III (53 patients in each group) showed that the median DFS for basal patients was 41.4 months (95% CI, 26.5-55.3 months), whereas the DFS for the luminal A patients was not reached (P = 0.014). After adjusting for several significant prognostics variables identified in a univariate analysis, a multivariate conditional logistic regression analysis identified the negative effect of lymphovascular invasion and the favorable influence of the use of neoadjuvant and/or adjuvant chemotherapy. This matched case-control study confirmed the poor clinical and pathological characteristics of patients with basal subtype and their unfavorable outcome compared with luminal A disease. Management of basal tumors remains a challenging task, and new therapeutic strategies are warranted.
