In the EC FP-7 MERASA project a hard real-time capable multi-core processor is developed. The system-level software represents an abstraction layer between application software and embedded hardware. It has to provide basic functions of a real-time operating system. This report presents requirements for a multi-threaded hard real-time capable system-level software in embedded systems and the tr...

This paper demonstrates that it is possible to obtain good, scalable parallel performance by coordinating multiple instances of unaltered sequential computational algebra systems in order to deliver a single parallel system. The paper presents the first substantial parallel performance results for SymGrid-Par, a system that orchestrates computational algebra components into a high-performance p...

In this paper, we review the literature on efficient task scheduling on multi-core system. The number of cores on one chip are increasing very rapidly. For achieving high performance without more power consumption and without heating up the system, multi-core processing technology is used. In addition for fully utilization of system resources in more efficient way task scheduler are developed, ...

Space systems are hard real-time systems, where the worst-case execution time (WCET) of tasks needs to be known to prove absence of deadline misses. For simple processor and memory architectures it is possible to statically derive a safe upper bound of the WCET. However, future requirements in more autonomous missions require more processing power. This increase in processing power is approache...

TiO2-SiO2 core-shell particles include of monodisperse silica core and nanostructured titania shell were synthesized by a multi-step coating process. The monodisperse silica spheres were synthesized by Stöber method and titania shell was obtained of a colloidal sol prepared by a hydrolysis–condensation reaction. The titania sol was deposited on monodisperse silica spheres by a multi-step coatin...

a comprehensive evaluation of the residual levels of organochlorine insecticides (ocis) in the sediment cores of cochin estuarine system (ces) is highlighted in this research article. it assessed the distribution pattern and impact of these xenobiotics in this environmental niche. fifteen persistent organochlorine compounds (ocs) were quantitatively analysed in the six sediment core samples col...

This paper presents Manifold benchmarking suite, which is useful to measure and compare the performance of state-of-the-art multi core processors based systems. Manifold targets traditional single core as well as more recent multi core processors. In addition, it is equally useful for uniprocessor as well as symmetric multiprocessor (SMP) systems. Manifold measures hardware, operating system, a...

Efforts to reduce energy consumption are being made across all disciplines. ICT’s contribution to global energy consumption and by-products such as CO2 emissions continues to grow, making it an increasingly significant area in which improvements must be made. This thesis focuses on software as a means to reducing energy consumption. It presents methods for profiling and modelling a multi-thread...
