    • An electric compressor, wherein an inverter device, which controls the operation of an electric motor by commands from an external control unit, is provided with a drive IC which computes drive signals of the electric motor based on the same, a switching circuit which converts the drive signals to rotation control signals of the electric motor, and an output signal control IC which cuts off input of the drive signals to the switching circuit at the time of an abnormality and wherein, furthermore, the drive IC is provided with a comparator which compares drive signals which are input to the switching circuit and computed values of the drive signals at a control unit inside the drive IC and, when the drive signals and the computed values do not match, the comparator makes the output signal control IC cut off input of the drive signals to the switching circuit.

    • An inverter circuit for a motor outputs three-phase AC currents, which are outputted from common connection points to stator coils, based on output voltage of a DC power source and a power supply capacitor by a switching operation of transistors. An inverter control circuit determines that a system main relay is turned off, upon receiving a main relay-off signal from an electronic control unit. The inverter control circuit turns on the low-side transistors, while turning off the high-side transistors. A discharge current flows from the positive electrode to the negative electrode of the power supply capacitor through the stator coil and the low-side transistors, so that electric charge stored in the power supply capacitor is discharged.

    • While temporal and spatial direct modes are both supported, the amount of temporarily-stored direct-mode prediction information is reduced, thereby reducing the memory bus bandwidth. A motion information generator combines a motion vector for an anchor block with the number of a reference picture of the anchor block, thereby generates motion information of the pixel block. A still-state determination unit determines whether or not the pixel block is considered still based on the motion vector for the anchor block and on the number of the reference picture. A selector selectively stores in a memory either an output of the motion information generator or a determination result of the still-state determination unit as direct-mode prediction information of the pixel block. A motion vector predictor predicts a motion vector for the pixel block in direct mode based on the direct-mode prediction information stored in the memory.
    • 虽然都支持时间和空间直接模式,但是减少临时存储的直接模式预测信息的量,从而减少存储器总线带宽。 运动信息生成器将锚块的运动矢量与锚块的参考图像的数量组合,从而生成像素块的运动信息。 静止状态确定单元基于锚块的运动矢量和参考图像的数量来确定是否仍然考虑像素块。 选择器选择性地将运动信息发生器的输出或静止状态确定单元的确定结果存储在存储器中作为像素块的直接模式预测信息。 运动矢量预测器基于存储在存储器中的直接模式预测信息,以直接模式预测像素块的运动矢量。
