The ultrasound device can be divided into three units according to its functions:
 Front-end unit: is in charge of the scan function of the ultrasound imaging system, and sends
the pre-processed imaging data to the back-end unit for post-process. The engine board takes
charge of front-end unit. The elements are shown above:
 The uploaded data on TR64 board are wired in daisy chain and sent to the engine board.
 Control interface, the clock, Rate, sub-module information management (in the place,
board ID) are all based on the engine board, which distributes to other sub-modules.
 The management functions of the probe decouple the transmitting/receiving channel, and
communicate with the engine board.
