Box 11-5020 Beirut 1107 2809 Lebanon Email ari@ Received 10 October 2004 We are concerned with the design implementation and validation of a perception SoC based on an ultrasonic array of sensors. The proposed SoC is dedicated to ultrasonic echography applications. A rapid prototyping platform is used to implement and validate the new architecture of the digital signal processing DSP core. The proposed DSP core efficiently integrates all of the necessary ultrasonic B-mode processing modules. It includes digital beamforming quadrature demodulation of RF signals digital filtering and envelope detection of the received signals. This system handles 128 scan lines and 6400 samples per scan line with a 90 angle of view span. The design uses a minimum size lookup memory to store the initial scan information. Rapid prototyping using an ARM FPGA combination is used to validate the operation of the described system. This system offers significant advantages of portability and a rapid time to market.
