This paper presents the issues associated with the real-time implementation of MELP 2.4 kbps speech codec by using a TI fixed-point DSP. It briefly reviews the MELP algorithm and the procedure used in porting the fixed-point MELP C codes into the TMS320C54x assembly codes. Various factors such as memory, speed and compatibility are also discussed
