This paper presents a real-time electrocardiogram (ECG) data compression processor with improved energy efficiency while maintaining high accuracy and real-time operation. Wavelet shrinkage is exploited to filter the noise and achieve sparse ECG signal representation. Adaptive temporal decimation is proposed to achieve configurable processing to adaptively reduce the data amount and computational...
Synthetic aperture (SA) imaging algorithm, which combines sub-aperture elements to form high resolution image, can improve image quality in vivo ultrasound image. However, large computation resource is generally required for the implementation of SA. In this paper, we propose a parallel structural design for SA imaging algorithm that can be realized in Field Programmable Gate Array (FPGA), so that...
