A power efficient channel coder/decoder chip for GSM terminals

A single-chip implementation of t h e GSM full-rate vocoder is presented.Maximum integration has been achieved through t h e use of DSP CORE technology. The impact of this technology on t h e design methodology and testability will b e described. This component is one of t h e key building blocks of t h e ALCATEL GSM handportable station. This chip is designed die size. 10.3.1 IEEE 1992 CUSTOM INTEGRATED CIRCUITS CONFERENCE 0-7803-0246-x/92 $3.00 1992 IEEE

A bs tra c tA new DSP architecture for equalizing, channel codingldecoding and encryptioddecryption required by GSM hand portable terminals is presented. In the DSP, which is called EQCHAN (Equalizer and Channel codingldecoding processor), these tasks are managed in common units, that is, the data processing unit (DPU) and the bit manipulation unit (BMU). The LSI that contains EQCHAN was designed using 0.8 pm CMOS technology arid its die size is 123mm2. The power consumed in the LSI is 6OmW at 3.6V under continuous communicatioin mode and this value is sufficient for a portable terminal. In this paper, we describe the detail architecture of EQCHAN.
