GENERAL DESCRIPTION
The EVAL-MELODY-8 board is a platform that allows users to
evaluate Analog Devices, Inc., products intended for decoding
high quality, digital audio signals.
The EVAL-MELODY-8 board includes a Blackfin® ADSP-
BF524 processor for system control and a SHARC®
ADSP-21569, which is a SHARC+® single core, high performance,
digital signal processor for audio decoding. The evaluation board
also includes the ADV7625 High-Definition Multimedia
Interface (HDMI®) transceiver with high bandwidth digital
content protection (HDCP) 1.4 technology. To order the EVALMELODY-8 board, the user must be licensed for the HDCP 1.4
technology.
Full specifications for the ADSP-21569 are listed in the
ADSP-21569 data sheet. Full specifications for the ADSP-BF524
are listed in the ADSP-BF524 data sheet. Consult the data
sheets in conjunction with this user guide when using the EVALMELODY-8 board.

EVALUATION BOARD SOFTWARE
The software on the E VA L -MELODY-8 board consists of
firmware and a configuration code running on the following
three devices:
• ADSP-BF524 application processor (U67)
• ADSP-21569 audio processor (U114)
• Xilinx® XC2C256 complex programmable logic device
(CPLD) (U28)
For the EVA L-MELODY-8 board to work correctly, configure
all three devices for the desired application. Request the software
and full documentation package for the E VA L-MELODY-8
board through the Software Request Form (SRF) process on the
Analog Devices website. For additional options, contact a local
Analog Devices sales or distribution representative.

Resource Description
ADSP-21569 SHARC+ Single Core High Performance DSP (Up to 1 GHz)
ADSP-BF524 Blackfin Embedded Processor
The software passes video from the HDMI RxA input to the TxA
output and processes the extracted audio in the ADSP-21569.The
line level analog audio output is available on Channel 1 to
Channel 8 of the P4 connector, and Channel 1 to Channel 8 of
the P1 connector. It is recommended to purchase the CS-2436-06
from Infinite Cables because its RCA cables are labeled with the
channel number.
