Reconfigurable Color Doppler DSP Engine for High-Frequency Ultrasonic Imaging Systems

Abstract

A single-chip reconfigurable Color Doppler DSP engine is presented. It acts as the computation kernel of the high-frequency ultrasonic imaging system under development. The flexibility of the proposed DSP engine enables users to acquire sufficient information as needed, while the specificity of the hardware compared to general-purpose processors reduces cost and power consumption. This chip is implemented by TSMC 0.18 ¿m 1P6M CMOS technology. The die size is 2.94*2.94 mm2, and the power consumption is 184 mW when frame rate = 50, frame size = 512*256, and packet size = 8.
