GSM/GPRS/EDGE-RX SOC Processor Technical Brief

MediaTek Inc 

1.7 General Descriptions

Figure 2Error! Reference source not found. is

the block diagram of MT6260. Based on a

multi-processor architecture, MT6260 integrates

an ARM7EJ-STM core, the main processor

running high-level GSM/EDGE-Rx protocol

software as well as multimedia applications,

single digital signal processor core, which

manages the low-level MODEM and advanced

audio functions, an embedded processor

running Bluetooth baseband and link control

protocol and the Bluetooth radio control.

MT6260 consists of the following subsystems:

 Microcontroller Unit (MCU) subsystem:

Includes an ARM7EJ-STM RISC processor

and its accompanying memory

management and interrupt handling logics

 Digital Signal Processor (DSP) subsystem:

Includes a DSP and its accompanying

memory, memory controller and interrupt

controller

 MCU/DSP interface: Junction at which the

MCU and the DSP exchange hardware and

software information

 Microcontroller peripherals: Include all user

interface modules and RF control interface

modules

 Microcontroller coprocessors: Run

computing-intensive processes in place of

the microcontroller

 DSP peripherals: Hardware accelerators for

GSM/GPRS/EDGE-Rx channel codec

 Multimedia subsystem: Integrates several

advanced accelerators to support

multimedia applications

 Voice front-end: Data path for converting

analog speech to and from digital speech

 Audio front-end: Data path for converting

stereo audio from an audio source

 Baseband front-end: Data path for

converting a digital signal to and from an

analog signal from the RF modules

 Timing generator: Generates the control

signals related to the TDMA frame timing

 Power, reset and clock subsystem: Manage

the power, reset and clock distribution

inside MT6260.

 Bluetooth subsystem: Includes an

embedded processor with embedded

ROM/RAM system, baseband processor,

and a high-performance radio block

 Power management unit: Self-contained

power supply source which also controls

the charging and system startup circuitry.

Details of the individual subsystems and blocks

are described in the following chapters.
