＜正＞DSP （Digital Signal Processing） processors have been more and more applied in all kinds of products. Real time processing and low power is marked character for them, and the computational unit in DSP Processors performs numeric processing for DSP algorithms and is bottle-neck for improving the performance of DSP processors. In this paper, we present a path of low power and concurrency exploitation in a general 16-bit fixed programmable DSP processors working on 200MHz, by which the computation performance is improved and the power is reduced by more than 35% based on software.

关键词： Computational unit shift-add low power. concurrency.

The total reaction cross section (1724±93 mb) of 17B at the energy of 43.7 A MeV on C target has been measured by using the transmission method at the Radioactive Ion Beam Line in Lanzhou (RIBLL). Assuming 17B consists of a core 15B plus two halo neutrons,the total cross section of 17B on C target was calculated with the zero-range Glauber model,where double Gaussian density distributions and Gaussian plus HO density distributions were used. It can fit the experimental data very well. The characteristic of halo structure for 17B was found with a large diffusion of the neutrons density distribution.

AIM: To investigate the effect of schisanhenol (Sal) on copper ion-induced oxidative modulation of human low density lipoprotein (LDL). METHODS: The antioxidative activity of eight schisandrins (DCL) on microsome lipid peroxidation induced by Vit C/NADPH system was first observed, and then, the effect of Sal on Cu2+-induced human LDL oxidation was studied. The generation of malondialdehyde (MDA), lipofuscin, reactive oxygen species (ROS), consumption of a-tocopherol as well as electrophoretic mobility of LDL were determined as criteria of LDL oxidation. Finally, the quantum chemical method was used to calculate the theoretical parameters of eight DCL for elucidating the difference of their antioxidant ability. RESULTS: Sal was shown to be the most active one among eight schizandrins in inhibiting microsome lipid oxidation induced by Vit C/NADPH. Sal 100, 50, and 10μmol/L inhibited production of MDA, lipofuscin and ROS as well as the consumption of a-tocopherol in Cu2+-induced oxidation of human LDL in a

The vertical distributions of the wind field and temperature field of the boundary layer were very peculiar in Qingdao area, china. Under the height of 1500m, the wind field appeared as one pike two valley type: the wind speed was relatively low near surface, got bigger between 300m to 400m, decreased over 500m, and increased again gradually over 1000m. The temperature stratification was stable in the morning and evening, and it became unstable below 200m after noon. As far as mixed layer was concerned, it was not very high, generally about 400m, sometimes it reached 700m high. Multiple layer inversion often appeared in low altitude. Northern wind was prevailing in winter, so southern in summer. The wind field was often influenced by Jianghuai cyclone and Huanghuai cyclone. Convergence air current between lower level and higher level emerged when the cyclones passed Qingdao area. Introducing straight and shear air current, pollutants emitted from point sources were modeled by advection diffusion equation. The result indicated that pollutants were transported far away under one straight air current. In rainy days, pollutants were accumulated in local area and the concentrations were high. When wind direction appeared shear between higher level and lower level,the transportation of pollutants was more limited. In rain days,acid rain was form by chemical process at a near distance.

To investigate the interactions of oppositely charged sites on the surfaces of variable-charge soil particles with cations and anions, and to evaluate the mean Gibbs free binding and adsorption energies of various cations on particles of red soil and latosol, clay fractions smaller than 2 μm were separated from samples of the two variable-charge soils. Ferric oxides were removed from part of the clay fractions, which were then saturated with various chlorides （NaC1, KCl, CaCl2, CdCl2 or LaCl3）. Electrical conductivities （EC） of dilute suspensions of the original and of the iron oxides-free clay fractions in deionized water were measured with the SHP-2 short high-voltage pulse apparatus, which enables measurement of the Wien effect at field strengths （E） from 14 to 250 kV cm^-1. The Wien effect （EC-E） curves revealed EC increases of red soil suspensions between 14 and 200 kV cm^-1, of 8.3, 8.4, 12.1, 5.9, and 1.2 μS cm^-1 for NaCl, KCl, CaCl2, CdCl2, and LaCl3, respectively, reflecting the differing interactions with the various cations and chloride. The EC increments with the iron-free red soil suspensions were higher, being 29.7, 17.2, and 15.3 μS cm^-1 for NaCl, CaCl2, and CdCl2, respectively. In the natural latosol suspensions the EC increments were practically zero, whereas in the iron-free fractions there were significant EC increments of 10.3, 5.7, 5.0, and 1.6μS cm^-1 for NaCl, CaCl2, CdCl2, and LaCl3, respectively.
