Nowadays, multi-core processors are widely used in embedded applications due to the advantages of higher performance and lower power consumption. However, the complexity of multi-core architectures makes it a considerably challenging task to extend a single-core version of a real-time operating system to support multi-core platform. This thesis documents the process of design and implementation...

In the software development for vehicular embedded systems, timing predictability is paramount for the development of the vehicles’ safety features and for their customer value. Modern vehicles’ features require new level of computational power. On the one hand, multicore platforms can provide efficient support for these features. On the other hand, multi-core platforms complicate the software ...

Tag reduction is an approach to save energy of the cache system in a processor. Our previous work described that it can save more energy on a Chip Multiprocessor (CMP) than on a single-core processor. In this paper, we further investigate the problem on balancing energy saving and performance overhead when tag reduction is used for the low power Chip Multiprocessor (CMP). We first introduce the...

DRAM system has been more and more critical on modern multi-core architecture where the Moore’s law has been made effect on increasing the number of cores integrated in a processor chip. The performance of DRAM system is usually measured in term of bandwidth and latency, which are regarded as inherently depending on Row Buffer Hit Rate (RBHR) according to previous studies. In this paper, we fin...

Title of dissertation: CROSS-LAYER CUSTOMIZATION FOR LOW POWER AND HIGH PERFORMANCE EMBEDDED MULTI-CORE PROCESSORS Chenjie Yu, Doctor of Philosophy, 2010 Dissertation directed by: Assistant Professor Peter Petrov Electrical and Computer Engineering Due to physical limitations and design difficulties, computer processor architecture has shifted to multi-core and even many-core based approaches i...

Long-term hydrographic temperature and salinity transect data in the East China Sea from June 1955 to November 2001 are analyzed in order to examine the geostrophic velocity and the structure of the Kuroshio current. The structure of the Kuroshio Current is divided into three basic forms, a single-core structure, a double-core structure and a multi-core structure; the appearance percentage of t...

The theory of scheduling has expanded rapidly during the past years. As multi-core architectures begin to emerge, operating system issues are to be considered for best use of multi-core processes. Due to the architectural differences in the state of art multi-core processors such as shared caches, memory controllers etc., it becomes the responsibility of the operating system to make use of inte...
