Based on a multi-processor architecture,

MT6260A integrates an ARM7EJ-S

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.

MT6260A consists of the following subsystems:

 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 MT6260A.
