With the explosive growth of mobile data traffic and rapidly rising energy price, how to implement caching at small cells in an energy-efficient way is still an open problem and requires further research efforts. In this paper, we study the energy-efficient context-aware resource allocation problem, which falls into the category of mixed integer nonlinear programming (MINLP) and is NP-hard. To provide...
Energy and performance efficiency of fetch unit is critical to processor design. Trace cache which stores dynamic instruction flow to form instruction trace can significantly improve performance efficiency by fetching multiple blocks from trace cache in a given cycle. Conventional trace cache (CTC) design suffers energy inefficiency because of its simultaneous access to both instruction cache and...
Ubiquitous technologies are indispensable for modernizing human daily life more and more. However, the technologies are not easily widespread everywhere in our world through infrastructures and other related techniques. We have worked on a project to meet these challenges with a goal to construct a framework for the coming ubiquitous society. In our previous works, we have proposed UMP-PerComp, a...
Energy consumption is a major consideration in microprocessor optimization. This paper presents a tag-reduction based approach for energy saving in L1 i-cache (instruction cache) of chip multiprocessors (CMP). To our best knowledge, this is the first work that extends the tag reduction technique to the CMP. We formulate our approach to an equivalent problem which is to find an assignment of the whole...
With the great progress of the Information Technologies, micro-processors are embedded into everywhere to make our daily life convenient, efficient and comfortable. However, how to integrate distributed resources existing among heterogeneous devices to build pervasive applications that can constantly adapt to the highly dynamic computing environment is still a challenge. On our previous work, by analyzing...
