Chapter 3: Explanation of Schematic
3.1 Typical application of MT6236
Based on a multi-processor architecture, MT6236 integrates an ARM926EJ-S
TM
core, the main
processor running high-level GSM/GPRS protocol software as well as multimedia applications,
two digital signal processor core, which manages the low-level MODEM as well as advanced
audio functions, and an ARM7EJ-S
TM
core, the dedicated processor running Bluetooth baseband
and link control protocol, as well as the Bluetooth radio control.
MT6236 consists of the following subsystems:
Microcontroller Unit (MCU) Subsystem: includes an ARM926EJ-S
TM
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: the junction at which the MCU and the DSP exchange hardware
and software information;
Microcontroller Peripherals: includes all user interface modules and RF control
interface modules;
