—Multiple-input–multiple-output (MIMO) systems use multiple antennas in both transmitter and receiver ends for higher spectrum efficiency. The hardware implementation of MIMO detection becomes a challenging task as the computational complexity increases. This paper presents the architectures and implementations of two typical sphere decoding algorithms ,(More)
This paper presents SmartCell as a novel power efficient reconfigurable architecture targeted for data streaming applications. We describe the design details of the SmartCell architecture, including processing element, reconfigurable interconnection fabrics, instruction and control process and dynamic configuration scheme. The performance in terms of power(More)
Recommended by Markus Rupp This paper presents SmartCell, a novel coarse-grained reconfigurable architecture, which tiles a large number of processor elements with reconfigurable interconnection fabrics on a single chip. SmartCell is able to provide high performance and energy efficient processing for stream-based applications. It can be configured to(More)
SUMMARY Fast Fourier Transform (FFT) is an important algorithm in many digital signal processing applications, and it often requires parallel implementation for high throughput. In this paper, we first present the SmartCell coarse-grained reconfigurable architecture targeted for stream processing. A SmartCell prototype integrates 64 processing elements,(More)
Wireless sensor network technology provides an opportunity for innovation. Their applications in urban environment have attracted many attentions recently. Due to the dynamic operational environment, the reliability and energy efficiency are two important criteria for the routing protocol designs of wireless sensor networks. This paper presents a heuristic(More)
Wireless networks that operate on batteries are imposed with energy constraints and long distance communications between nodes are not desirable. Implementing Relay Nodes (RNs) can improve network capacity and save communication energy. A two-hop relay routing scheme is considered, in which the RNs are temporarily placed and have energy constraints. This(More)
This study describes that the current rectification ratio, R ≡ |J|(-2.0 V)/|J|(+2.0 V) for supramolecular tunneling junctions with a top-electrode of eutectic gallium indium (EGaIn) that contains a conductive thin (0.7 nm) supporting outer oxide layer (Ga2O3), increases by up to four orders of magnitude under an applied bias of >+1.0 V up to +2.5 V; these(More)
Akebia Fructus has long been used for hepatocellular carcinoma (HCC) in China, while the molecular mechanism remains obscure. Our recent work found that Akebia trifoliate (Thunb.) Koidz seed extract (ATSE) suppressed proliferation and induced endoplasmic reticulum (ER) stress in SMMC-7721. The present study aimed to throw more light on the mechanism. ER(More)
This paper presents hardware/software co-design architecture targeted on a single FPGA for two typical lattice decoding algorithms in MIMO system. Two levels of parallelisms are analyzed for an efficient implementation with the preprocessing part on embedded MicroBlaze soft processor and the decoder part on customized hardware. The system prototypes of the(More)
When the financial crisis have happened in 2008, in the economy scholars it causes a large number of research about the Causes, process, form and results of financial crisis, as well as reflects on the development of real estate, banking and other industries, and discusses largely the financial sector how to develop, to avoid risks and recovery the global(More)
