To evaluate the real time performance of proposed algorithm, the time-scaling expansion of speech signal algorithm was implemented using a TMS320C6711 DSK [19,20], from Texas Instruments, programmed using the Code Composer Studio (CCS) from the same company. The TMS320C6711 DSK is a DSP development board based on the TMS320C6711 floatingpoint digital signal processor (DSP), which contains a 16 bit audio codec TLC320AD535 with a sampling rate of 8 kHz, an SDRAM of 16 MBytes, 3 user DIP switches, 3 user LEDs and a FLASH memory of 128 kBytes. This DSP is able to 600 MFLOPS or 1200 million instructions per second (1200 MIPS).
