    • To satisfy a required processing speed and achieve the maximum power-saving effect in a microprocessor. A control value is calculated by performing proportional and integral processing on a deviation of a target instruction execution number from a measured instruction execution number. Unification processing or unification cancellation processing is performed in accordance with the control value. The unification processing stops supply of clocks to selected pipeline registers and controls the pipeline such that a signal passes through the pipeline registers so as to reduce the number of stages of the pipeline. The unification cancellation processing resumes the supply of clocks to the selected pipeline registers and controls the pipeline such that the pipeline registers latch the signal in synchronism with the clocks so as to increase the number of stages of the pipeline. The frequency of clocks supplied to the pipeline registers is changed in accordance with the changed number of stages.
    • 为了满足所需的处理速度并在微处理器中达到最大的省电效果。 通过对目标指令执行次数与测量指令执行次数的偏差进行比例积分处理来计算控制值。 根据控制值进行统一处理或统一解除处理。 统一处理停止向所选流水线寄存器提供时钟,并控制流水线,使得信号通过流水线寄存器,以减少流水线的级数。 统一取消处理恢复向所选择的流水线寄存器提供时钟并控制流水线,使得流水线寄存器与时钟同步地锁存信号,以增加流水线的级数。 提供给流水线寄存器的时钟频率根据改变的级数而改变。

    • A storage capacitor is constituted by a storage capacitor electrode, made of a transparent and conductive film extending substantially all over a substrate, and pixel electrodes overlapping with the storage capacitor electrode via an interlevel insulation layer. The storage capacitor holds charges. The storage capacitor electrode is positioned such that it faces the entire surface of the pixel electrodes. Since the transparent and conductive storage capacitor electrode does not reduce the aperture ratio, the storage capacitor can have a large capacitance. A signal voltage applied to the storage capacitor electrode is determined so as not to activate the thin film transistors which are not selected. A light-shielding layer is present at a position between pixel electrodes on or under the storage capacitor electrode. The light-shielding layer shields the thin film transistors, gate lines and drain lines from incident light, thereby preventing reduction of contrast of displayed pictures. Further, an anti-reflection layer formed by heat treatment is placed on a boundary between the storage capacitor electrode and the light-shielding layer, and is effective in assuring visibility of the picture on the liquid crystal display.
    • 存储电容器由保持电容器电极构成,该电容器电极由基本上遍布基板延伸的透明导电膜和通过层间绝缘层与辅助电容电极重叠的像素电极构成。 存储电容器保持电荷。 存储电容电极被定位成使其面对像素电极的整个表面。 由于透明导电保持电容电极不会降低开口率,因此存储电容器可以具有大的电容。 确定施加到存储电容器电极的信号电压,以便不激活未被选择的薄膜晶体管。 在保持电容电极上或其下的像素电极之间的位置处存在遮光层。 遮光层将薄膜晶体管,栅极线和漏极线遮挡入射光,从而防止显示图像的对比度降低。 此外,通过热处理形成的抗反射层被放置在保持电容电极和遮光层之间的边界上,并且有效地确保了液晶显示器上的图像的可视性。
