Memcached is an in-memory key-value caching system, which is used to resolve the principal contradiction of the disk-based database between the CPU and input/output, has been widely used as an effective way to solve the distance and improve the capacity of the source server. We optimize the performance of Memcached memory access through two ways: improve the density of memory storage and ameliorate...
High functional complexity is leading us towards new architectures for sensing systems. Multi-tiered design is one among the many emerging alternatives. Such architectures bring new opportunities for effective system-level power management. For instance, varying one/more tier-level parameters can provide substantial end-to-end energy scaling. In this paper, we review an existing approach that shows...
Test technique with multiple scan chains can fully reduce test time, but more data input channels, higher hardware overhead, lower test data compression ratio and lower fault coverage along with it are all paid more extensive attention to in the current test field. A cyclic shift compression technique is proposed and applied to multiple scan chain testing. Unlike general shift, cyclic shift technique...
SPIHT is computationally very fast and among the best image compression algorithms known today. According to statistic analysis of the output binary stream of SPIHT encoding, propose a simple and effective method combined with Huffman encode for further compression. A large number of experimental results are shown that this method saves a lot of bits in transmission, further enhanced the compression...
This article presents a relative complete desktop vision system (DVS) for 3D model reconstruction based image pairs, which can be used for modeling in virtual engineering. In the system, object feature data is measured with photogrammetry technologies; noise is filtered in adaptive morphology method; data is then compressed via non-uniform grid and median filtering. Experiments prove that the result...
Orthogonality and symmetry are desirable transform properties in image compression. And most multiwavelet can hold the two properties concomitantly. While the choice of pre-filter is of the utmost importance and pre-filtering brings complexity of computation in applications. Thereby, balanced multiwavelet which can avoid pre-filtering is considered widely by researchers. A new approach on the construction...
