signal processor.
MT6235consists of the following subsystems:
Microcontroller Unit (MCU) Subsystem: includes an ARM926EJ-S 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;
Microcontroller Coprocessors: runs computing-intensive processes in place of the
Microcontroller;
DSP Peripherals: hardware accelerators for GSM/GPRS/EDGE channel codec;
Multi-media Subsystem: integrates several advanced accelerators to support multi-media
applications;
Voice Front End: the data path for converting analog speech to and from digital speech;
Audio Front End: the data path for converting stereo audio from an audio source;
Baseband Front End: the 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; and,
Power, Reset and Clock Subsystem: manages the power, reset, and clock distribution inside
MT6235.
