Abstract :
One of the most efficient procedures for solving the LPC (Linear Prediction Coding) coefficients Problem is the Levinson-Durbin Algorithm that has been widely adopted in practical system design. However with advanced Development in Multimedia and Telephony system, the Software Implementation of such Algorithms on DSP Processors doesn´t satisfy the speed requirements of these systems. Given that, in this work, with the design of a flexible system we present an efficient model for hardware implementation of The LPC Feature Extraction System, based on Levinson-Durbin Algorithm. The proposed architecture for Levinson-Durbin recursive Algorithm significantly reduced the resource utilization. Flexibility in coefficient´s order, along with Pipeline technique exploitation, improves our proposed system performance.
