这是H.264解码部分:4*4残差块的IDCTARM汇编代码部分.-This is the H.264 codec : 4* 4 residuals block IDCTARM compiled code part.

步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，即给电机加一个脉冲信号，电机则转过一个步距角。-Stepper motor is the electrical impulse signals into angular displacement or linear displacement of the open-loop control components. In the non-overload case, the motor speed, and stop location depends only on pulse frequency and pulse number, regardless of the load change, that is, to add an electrical pulse signal, then turn one motor step angle.
