In this paper we present a flexible circuit that allows for a parallel and partially asynchronous multiplication of matrices. The circuit, realized in the CMOS technology, has been designed for the application, for example, in fast Kalman filtering in automotive active safety applications. In such filters we encounter numerous operations performed on matrices that are time consuming. Additionally,...
The paper presents a novel circuit for the calculation of Manhattan distance between two vectors of signals, suitable for various machine learning algorithms realized at the transistor level. In Self-Organizing Artificial Neural Networks, for example, one of the basic operations is the calculation of a distance between input learning patterns and vectors of neuron weights. In pattern recognition two...
The paper presents a low power and low chip area decimation filter for a 15-bits Σ-Δ analog-to-digital converter (ADC) designed for a flywheel MEMS gyroscope. In contrary to typical solutions, in which decimation is performed after each filtering stage, in the proposed approach all filter sections operate at the sampling frequency of the modulator. The low power dissipation is in this case achieved...
