Abstract |
In this work, we present SIMUIINK bit-true
modeling of the conjugate structure-algebraic CELP
(CS-ACELP) speech coder which has been chosen as
the core layer of speech coder standard ITU-T
G.729.1. The optimum bit numbers of the
computational blocks are defined as the minimum
word-widths that maintain the quality of the output
with minimum chip area and power. Such optimum bitwidth
of the coefficients and the internal computations
are extracted. As a result, a golden model of the codec
which best suits as a reference for its hardware
implementation is developed. The power and area
improvements are estimated in two blocks of CSACELP
speech coder. |
