A dynamic voltage stress (DVS) condition optimization includes selecting a testing block from a plurality of blocks in a die of a wafer, acquiring a plurality of testing block measurement temperatures of the testing block when the testing block is processed by a DVS testing flow, acquiring a correlation table of the plurality of testing block measurement temperatures and a plurality of DVS block predict temperatures of the testing block, configuring a tip burnt block temperature according to the testing block measurement temperatures, determining a DVS block target temperature selected from the DVS block predict temperatures according to the correlation table and the tip burnt block temperature, and generating a DVS block voltage for applying to the testing block in the die of the wafer according to the DVS block target temperature.

An image scaler includes a horizontal downscaler, a horizontal upscaler, and a vertical scaling unit. The horizontal downscaler is configured in front of the vertical scaling unit and the horizontal upscaler is configured in back of the vertical scaling unit, so as to operate in coordination with a selective control method. The selective control method controls an image input route depending on horizontal downscaling or upscaling requirements, so as to choose to go through or to bypass the horizontal downscaler or the horizontal upscaler to horizontally and vertically resize an image. In this way, the input signal is processed in only two stages, so that the present invention can not only reduce the process loading of the huge amount of the data volume in the final stage, and also can reduce power consumption.

An organic electrolyte for use in a lithium secondary battery comprising a lithium salt dissolved in an organic solvent mixture is disclosed. The lithium salt can be LiClO.sub.4, LiPF.sub.6, LiBF.sub.4, LiCF.sub.3 SO.sub.3, LiAsF.sub.6, or other lithium salt, and the organic solvent mixture contains a carbonate and an acetate. The carbonate is ethylene carbonate, and the acetate can be either methyl acetate or ethyl acetate. The carbonate and the acetate are provided in a ratio of carbonate/acetate ranging from 80/20 to 20/80, or preferably from 40/60 to 60/40, and said lithium salt has a concentration of between 0.6 and 1.5M, or preferably at about 1M. The electrolyte exhibits excellent stability in a lithium secondary battery having a cathode which contains either LiCoO.sub.2 or LiMn.sub.2 O.sub.4, and can withstand charge/discharge voltages of at least as high as 5 V (vs. Li/Li.sup.+), with excellent service life.
