MAD2
MAD2 contains following building blocks:
– ARM RISC processor with both 16–bit instruction set (THUMB mode)
and 32–bit instruction set (ARM mode)
– TI Lead DSP core with peripherials:
– API (Arm Port Interface memory) for MCU–DSP commu-nication,
DSP code download, MCU interrupt handling vec-tors
(in DSP RAM) and DSP booting
– Serial port (connection to PCM)
– Timer
– DSP memory
– BUSC (BusController for controlling accesses from ARM to API, Sys-tem
Logic and MCU external memories, both 8– and 16–bit memories)
– System Logic
– CTSI (Clock, Timing, Sleep and Interrupt control)
– MCUIF (Interface to ARM via BUSC). Contains MCU Boo-tROM
– DSPIF (Interface to DSP)
– MFI (Interface to COBBA AD/DA Converters)
– CODER (Block encoding/decoding and A51&A52 ciphering)
– AccIF(Accessory Interface)
– SCU (Synthesizer Control Unit for controlling 2 separate
synthesizer)
– UIF (Keyboard interface, serial control interface for COBBA
PCM Codec, LCD Driver and CCONT)
– SIMI (SimCard interface with enhanched features)
– PUP (Parallel IO, USART and PWM control unit for vibra
and buzzer)
The MAD2 operates from a 13 MHz system clock, which is generated
from the 13Mhz VCXO frequency. The MAD2 supplies a 6,5MHz or a
13MHz internal clock for the MCU and system logic blocks and a 13MHz
clock for the DSP, where it is multiplied to 52 MHz DSP clock. The system
clock can be stopped for a system sleep mode by disabling the VCXO
supply power from the CCONT regulator output. The CCONT provides a
32kHz sleep clock for internal use and to the MAD2, which is used for the
sleep mode timing. The sleep clock is active when there is a battery volt-age
available i.e. always when the battery is connected.
