Overview: This paper describes a design experiment on the implementation of the digital part of a low power 16-channel ultrasound beam former ASIC. The design is based on a physically oriented design methodology applying a data path generator for automatic layout generation and a quantitative optimization of all building blocks for lowest possible power dissipation. In addition to an optimized degree of pipelining, the use of the data path generator preserves locality, the key to disruptive technology power features. The application of appropriate number representation in arithmetic building blocks, clustered supply voltage techniques, and customized memory blocks, among other power reduction strategies, allowed the attainment of unequalled power figures.
