1.2 Functional Overview of the DM355 EVM
1.3 Basic Operation
1-4
The DM355 on the EVM interfaces to on-board peripherals through the 8/16-bit wide
EMIF peripheral interface pins. The DDR2 memory is connected to its own dedicated
16 bit wide bus. The EMIF bus is also connected to the NAND Flash and ethernet
controller.
On board video decoder and on chip encoder interface video streams to the DM355
processor. One decoder and 1 on chip DAC channel are standard on the EVM. On
screen display functions are implemented in software on the DM355 processor.
An on-board AIC33 codec allows the DSP to transmit and receive analog audio
signals. The I
the audio stream. Signal interfacing is done through 3.5mm audio jacks that correspond
to microphone input, headphone output, line input, and line output.
The EVM includes 8 user LEDs, a 4 position user DIP switch, an IR interface, a Real
time clock along with 5 user push button switches to provide the user with application
interaction. These interfaces are implemented via software on a MSP430 and are
accessed by reading and writing to the I
An included +5V external power supply is used to power the board. On-board switching
voltage regulators provide the +1.3V CPU core voltage, +3.3V for peripherals and
+1.8V for DDR2 memory. The board is held in reset by the on board MSP430
microcontroller until these supplies are within operating specifications.
Code Composer Studio communicates with the EVM through an external emulator via
the 14 pin external JTAG connector.
The EVM is designed to work with TI’s Code Composer Studio development, or
standard GDB tool environments. Code Composer communicates with the board
through an external JTAG emulator. To start, follow the instructions in the Quick Start
Guide to install Code Composer. This process will install all of the necessary
development tools, documentation and drivers.
