Abstract :
This paper presents 16-bit DSP processor and system for baseband and voiceband processing of IS-136 digital cellular telephony that is North America TDMA standard. The DSP, named MIGHTI, that is designed for mobile communication applications, has some special instructions that allow instruction pipelining for the compound operations. MIGHTI includes a low-power 16 K-word flexible port fullcustom memory. With MIGHTI, IS-136 baseband and voiceband processing that normally requires 45 MIPS in a conventional DSP, is performed in just 36 MIPS. The system developed for baseband and voiceband processing does meet the requirements of the IS-136 standard
