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.La présente invention concerne un procédé de traitement parallèle à grande vitesse d'un signal ultrasonore, le procédé servant à générer une image ultrasonore au moyen d'un dispositif intelligent pourvu d'une unité de traitement graphique (GPU) mobile, par la réception d'une entrée consistant en un signal ultrasonore. Le procédé comprend les étapes consistant à : recevoir une entrée consi
