Abstract—Pulsed Wave (PW) spectrum Doppler ultrasound is a a general-purpose oriented API for its graphics hardware, with
valuable tool for clinical diagnosis for flow velocity distribution the G9800 processor as the target platform [4]. This platform
in vessels. However, real-time processing of PW spectrum is also provides support for standard C programming with certain
computationally intensive, involving wall filtering, Fast Fourier extensions which makes programming on the GPU more
Transform (FFT), column filtering and linear averaging. In this straightforward for C software developers.
