Present a low power, miniaturized biomedical sensor node featuring electro-, seismo-and gyrocardiography. Measurement session can be set up and controlled over Bluetooth Low Energy interface. Acquired raw or preprocessed sensor data can be stored locally to the microSD memory card. To the best of the authors' knowledge, the presented device is the smallest reported to enable heart monitoring from...
In this paper we present a CMOS implementation of a 512×512-cell Associative Content Addressable Memory (ACAM) in 180 nm CMOS. The memory can be operated either as an associative CAM or it can be configured into a Willshaw memory for operating with sparse data. The vector matching operation can use a tunable hit threshold or the strongest hit can be selected with a winner-take-all (WTA) network. Built-in...
