TMS320DM647/TMS320DM648
Digital Media Processor
SPRS372–MAY 2007
TMS320DM647/DM648 Digital Signal Processor (DSP). The EDMA3 controller’s primary
purpose is to service user-programmed data transfers between two memory-mapped slave
endpoints on the DSP.

TMS320DM647/DM648
describes the peripheral component interconnect (PCI) port in the TMS320DM647/DM648
Digital Signal Processor (DSP). The PCI port supports connection of the C642x DSP to a
PCI host via the integrated PCI master/slave bus interface. The PCI port interfaces to the
DSP via the enhanced DMA (EDMA) controller. This architecture allows for both PCI master
and slave transactions, while keeping the EDMA channel resources available for other
applications.

TMS320DM647/DM648 DSP Host Port Interface (UHPI) User's Guide
describes the host
port interface (HPI) in the TMS320DM647/DM648 Digital Signal Processor (DSP). The HPI is
a parallel port through which a host processor can directly access the CPU memory space.
The host device functions as a master to the interface, which increases ease of access. The
host and CPU can exchange information via internal or external memory. The host also has
direct access to memory-mapped peripherals. Connectivity to the CPU memory space is
provided through the enhanced direct memory access (EDMA) controller.

TMS320DM647/DM648 DSP Universal Asynchronous Receiver/Transmitter (UART)
User's Guide
describes the universal asynchronous receiver/transmitter (UART) peripheral
in the TMS320DM647/DM648 Digital Signal Processor (DSP). The UART peripheral
performs serial-to-parallel conversion on data received from a peripheral device, and
parallel-to-serial conversion on data received from the CPU.
SPRUEL9
TMS320DM647/DM648 DSP VLYNQ Port User's Guide
describes the VLYNQ port in the
TMS320DM647/DM648 Digital Signal Processor (DSP). The VLYNQ port is a high-speed
point-to-point serial interface for connecting to host processors and other VLYNQ compatible
devices. It is a full-duplex serial bus where transmit and receive operations occur separately
and simultaneously without interference.

TMS320DM647/DM648 DSP Video Port/VCXO Interpolated Control (VIC) Port User's
Guide
discusses the video port and VCXO interpolated control (VIC) port in the
TMS320DM647/DM648 Digital Signal Processor (DSP). The video port can operate as a
video capture port, video display port, or transport stream interface (TSI) capture port. The
VIC port provides single-bit interpolated VCXO control with resolution from 9 bits to up to 16
bits. When the video port is used in TSI mode, the VIC port is used to control the system
clock, VCXO, for MPEG transport stream.
SPRUEM2
TMS320DM647/DM648 DSP Serial Port Interface (SPI) User's Guide
discusses the Serial
Port Interface (SPI) in the TMS320DM647/DM648 Digital Signal Processor (DSP). This
reference guide provides the specifications for a 16-bit configurable, synchronous serial
peripheral interface. The SPI is a programmable-length shift register, used for high speed
communication between external peripherals or other DSPs.
