This paper presents VLSI design for sound-source localization by computing time difference of arrival (TDOA). Real-time computation yet few logic element consumption are targeted for this architecture. This system supports to recognize sound direction in 3 dimensional space by utilizing 4 sound sensors. In order to determine sound direction, we propose efficient cross-correlation method for TDOA computation...
A visible light communication (VLC) system design for wearable patient monitoring device is proposed in this paper. This system consists of two devices, patient and coordinator devices. It is two-ways communication scheme. The downlink communication uses VLC, while the uplink uses infrared. It can help the doctor to monitor the patient's condition. Moreover, VLC technology is considered to be safer...
In this paper, we present a VLSI design of human detection using Sum of Absolute Difference (SAD) based parallel morphological template matching method. Its research targets are to achieve small area consumption yet with fast computation. The architecture is designed to process original and its template images with resolution of 640×480 and 40×100 pixels respectively. Here, we propose two techniques,...
