ASIC implementation of efficient line spectral frequency computation for speech coding applications
D.L. Reynolds, Linda M. Head, Ravi P. Ramachandran · 2006
One of the more computationally intensive portions of speech coding algorithms using linear predictive (LP) methods is the calculation of line spectral frequencies (LSFs) from the predictor coefficients. Methods for the efficient computation of LSFs have been developed. A very large scale integration (VLSI) design implementing one such method is presented. The architecture is designed to be optimized for speed and area and is suitable for integration into larger speech coding systems.
