The present invention relates to a method for high-speed parallel processing for an ultrasonic signal, the method used for generation of an ultrasonic image by a smart device, which is provided with a mobile graphic processing unit (GPU), by receiving an input of an ultrasonic signal. The method comprises the steps of: receiving an input of an ultrasonic signal beam-formed by means of a first rendering cycle, removing a DC component from the ultrasonic signal, and then separating an in-phase component and a quadrature component from the ultrasonic signal, from which the DC component has been removed, and separately outputting same; a smart device performing quadrature demodulation and envelope detection processing for the ultrasonic signal, having the in-phase component and the quadrature component, by means of a second rendering cycle; and the smart device performing scan conversion for the ultrasonic signal, which has been obtained as the result of the second rendering cycle, by means of a fifth rendering cycle, wherein the rendering cycles are formed as a graphics pipeline structure comprising a vertex shader procedure, a rasterizer procedure, and a fragment shader procedure. A method for high-speed parallel processing for an ultrasonic signal by using a smart device, according to the present invention, enables high-speed parallel processing for an ultrasonic signal by means of a mobile GPU inside a smart device even in a mobile-based environment instead of a PC-based environment, thereby enabling the providing of an image having a frame rate that is useful for medical diagnosis.
