A Transcranial Doppler ultrasound system measures blood flow velocity of brain vessels. It displays power spectrum density to the computer display and measures other important parameters. For this measurement, transmission speed between equipment and a computer plays an important role. In order to provide processing of high rate data communication, most Transcranial Doppler ultrasound systems use digital signal processor which performs the process in hardware and is connected by a universal serial bus controller to the processor. This research presents a new design of the Transcranial Doppler ultrasound system using CY7C68013 without digital signal processor and general programmable interface waveform of the CY7C68013 for the Transcranial Doppler ultrasound system. Also, this research describes control library for the personal computer and implemented software. According to the implemented software, the processing of Transcranial Doppler ultrasound system can be carried out.
