This paper presents a novel high-speed lowcomplexity pipelined degree-computationless modified Euclidean (pDCME) algorithm architecture for high-speed RS decoders. The pDCME algorithm allows elimination of the degree-computation so as to reduce hardware complexity and obtain high-speed processing. A high-speed RS decoder based on the pDCME algorithm has(More)
Network-on-Chip (NoC) based Multi-Processor System-on-Chip (MPSoC) architecture is a promising SoC design solution, offering high computational power with lots of flexibilities. However, finding the optimal MPSoC architecture configuration remains an enormous challenge due to its high structural complexity and functional diversity. In this paper, we(More)
Deguelin exhibits potent apoptotic and antiangiogenic activities in a variety of transformed cells and cancer cells. Deguelin also exhibits potent tumor suppressive effects in xenograft tumor models for many human cancers. Our initial studies confirmed that deguelin disrupts ATP binding to HSP90 and consequently induces destabilization of its client(More)
The Hsp90 facilitates proper folding of signaling proteins associated with cancer progression, gaining attention as a target for therapeutic intervention. The natural rotenoid deguelin was identified as an Hsp90 inhibitor, but concerns about neurotoxicity have limited prospects for clinical development. In this study, we report progress on deguelin(More)
Generating soft information in list sphere decoder (LSD) increases the computational complexity to select a specific number of candidate lattice points. Among the techniques to reduce the computational complexity, we find that real-valued operation is able to reduce the per-node complexity, ordering process, and storage elements significantly with some(More)
The paper presents a new memory-addressing scheme for the realization of low power FFT processors. The scheme is based on the minimization of coefficient access and the reduction of switching activity by modifying the butterfly sequence. Therefore, power consumption in the complex multiplier and memory is significantly saved.
