Reserved. These pins must be connected directly to
1.8-V I/O supply(DVDD18) for proper device operation.
Reserved. This pin must be connected to the 1.8-V I/O
supply (DVDD18) via a 200-
resistor for proper device
operation.
NOTE: If the DDR2 Memory Controller is not used, the
V
, RSV19, and RSV20 pins can be directly
connected to ground (V
) to save power. However,
connecting these pins directly to ground will prevent
boundary scan from functioning on the DDR2 Memory
Controller pins. To preserve boundary-scan functionality
on the DDR2 Memory Controller pins, see
Section 6.3.6

TI offers an extensive line of development tools for the TMS320DM64x DMP platform, including tools to
evaluate the performance of the processors, generate code, develop algorithm implementations, and fully
integrate and debug software and hardware modules. The tools support documentation is electronically
available within the Code Composer Studio Integrated Development Environment (IDE).
The following products support development of TMS320DM64xx DMP-based applications:
Software Development Tools:
Code Composer Studio Integrated Development Environment (IDE): including Editor
C/C++/Assembly Code Generation, and Debug plus additional development tools
Scalable, Real-Time Foundation Software (DSP/BIOS), which provides the basic run-time target
software needed to support any SoC application.
Hardware Development Tools:
Extended Development System (XDS) Emulator (supports TMS320DM64x DMP multiprocessor
system debug) EVM (Evaluation Module)
