PROJECT TITLE :

VLSI Design for Convolutive BlindSource Separation - 2016

ABSTRACT:

This temporary presents an efficient very-large-scale integration design style for convolutive blind supply separation (CBSS). The CBSS separation network derived from the knowledge maximization (Infomax) approach is adopted. The proposed CBSS chip style consists mainly of Infomax filtering modules and scaling factor computation modules. In an Infomax filtering module, input samples are filtered by an Infomax filter with the weights updated by Infomax-driven stochastic learning rules. As for the scaling factor computation module, all operations including logistic sigmoid are integrated and implemented by the circuit style based on a piecewise-linear approximation scheme. The proposed prototype chip is implemented via a semi-custom design using ninety-nm CMOS technology on a die size of approximately zero.54 × zero.54 mm2.
