Real Time Implementation of TETRA Speech Codec on TMS320C54x

چکیده
This paper, partly tutorial in nature, describes an approach to the implementation of the 4.567 kbps TETRA speech codec on the TMS320C54x DSP family. The TETRA system is introduced and its speech codec is described in detail. The TETRA standard describes the speech codec in bit-exact, fixed-point C-code. Our paper compares the efficiency of implementing this code by first writing it in C and cross-compiling it and directly hand-coding it in TMS320C54x assembly code.
