Agenda Background AD20msp430 SoftFone® Chipset Digital Baseband Controller - AD6526 ADSP-2181 Why ADSP-2181 Not ADSP-21061 Question
3
Background December 15, 2003 – Analog Devices joint development with TCL Mobile Communication Co., Ltd. on GSM mobile phones Why TCL Mobile Communication CO. –Population 1.3 billion in China 28 million in Shanghai and Beijing –TCL Customer 9.8 Million in 2003 100.8 Million US Dollars Net Profit in 2003
4
AD20msp430 SoftFone® Chipset Analog Devices’ Fourth Generation GSM BaseBand Chipset –Color Displays, Camera, Games, and Polyphonic Ring Tones Consists Two Chips –Digital Baseband Controller AD6522, AD6526, AD6528 –Analog/Mixed-Signal Interface Chip AD6521, AD6535

ADSP-2181Data Transfer Five Internal Buses 1.Program Memory Address (PMA) Bus – 14 bits 2.Data Memory Address (DMA) Bus – 14 bits 3.Program Memory Data (PMD) Bus – 24 bits 4.Date Memory Data (DMD) Bus – 16 bits 5.Result (R) Bus – 16 bits 16-bits Internal DMA Port
12
Why ADSP-2181 Not ADSP-21061 Fast External Memory Access –External Address Bus –External Data Bus –Internal DMA Port –Byte DMA Port Simultaneously Communication Port –Two 5-bits Serial Port
13
Why ADSP-2181 Not ADSP-21061 Parallel Operation –ADSP-21061 is designed for FIR filter –ADSP-2181 is designed for Signal Convolution PowerDown Control Logic –Protect from Sudden High Signal Power Other Features –Double Metal –Low Power (1.7V Vs 5.0 V)
