Abstract
This research develops the software of DSP Processor type TMS320C54X for the CDMA circuitry. This research applytwo algorithms namely Mathematic Algorithm and table lookup Algorithm. From both algorithms, the research examinewhat algorithm have the fasted processing time and the smallest memory occupation. From the examination results theMathematic Algorithm have 20.62 milliseconds processing time and the Table lookup algorithm have 14.08 millisecondsprocessing time. The Table lookup algorithm have the fastest processing time because the Matematic algorithm need therounding process of the fi gure. Eventhough such processing time is not exceed from the 125 millisecond of delay time, inreal condition, the total processing time are include the error correction processing time and voice compression processingtime such as ADPCM or QCELP voice compression techniques.Keywords: DSP, digital signal processing, CDM
