GX500 Operational Description
3.2.1.1 General Description
S-GOLD3 TM is a GSM/EDGE single chip mixed signal Baseband IC containing all analog and digital functionality
of a cellular radio. Additionally S-GOLD3
MP3 sound. It is designed as a single chip solution, integrating the digital and mixed signal portions of the
base band in 0.09um, 1.2V technology.
The chip will fully support the FR, EFR, HR and AMR-NB vocoding.
S-GOLD3 TM support multi-slot operation modes HSCSD (up to class 10), GPRS for high speed data application
(up to class 12) and EGPRS (up to class 12) without additional external hardware.
3.2.1.2 Block Description

- 8k Byte tightly coupled memory for Program(internal)
- 8k Byte Cache for Data(internal)
- 8k Byte tightly coupled memory for Data(internal)
DSP-Memory
- 104K x 16bit Program ROM
- 8k x 16bit Program RAM
- 60k x 16bit Data ROM
- 37k x 16bit Data RAM
- Incremental Redundancy(IR) Memory of 35904 words of 16bit
Shared Memory Block
1.5K x 32bit Shared RAM(dual ported) between controller system and TEAKLite.
Controller Bus system
The processor cores and their peripherals are connected by powerful buses.
Multi-layer AHB for connecting the ARM and the other master capable building blocks with the internal
and external memories and with the peripheral buses.
Clock system
The clock system allows widely independent selection of frequencies for the essential parts of the S-GOLD3.
Thus power consumption and performance can be optimized for each application.
