SPRUEK8 — TMS320DM647/DM648 DSP Inter-Integrated Circuit (I2C) Module User's Guide
describes the inter-integrated circuit (I2C) peripheral in the TMS320DM647/DM648 Digital Signal
Processor (DSP). The I2C peripheral provides an interface between the DSP and other devices
compliant with the I2C-bus specification and connected by way of an I2C-bus. External components
attached to this 2-wire serial bus can transmit and receive up to 8-bit wide data to and from the
DSP through the I2C peripheral. This document assumes the reader is familiar with the I2C-bus
specification.
SPRUEL0 — TMS320DM647/DM648 DSP 64-Bit Timer User's Guide describes the operation of the
64-bit timer in the TMS320DM647/DM648 Digital Signal Processor (DSP). The timer can be
configured as a general-purpose 64-bit timer, dual general-purpose 32-bit timers, or a watchdog
timer.
SPRUEL1 — TMS320DM647/DM648 DSP Multichannel Audio Serial Port (McASP) User's Guide
describes the multichannel audio serial port (McASP) in the TMS320DM647/DM648 Digital Signal
Processor (DSP). The McASP functions as a general-purpose audio serial port optimized for the
needs of multichannel audio applications. The McASP is useful for time-division multiplexed (TDM)
stream, Inter-Integrated Sound (I2S) protocols, and intercomponent digital audio interface
transmission (DIT).
SPRUEL2 — TMS320DM647/DM648 DSP Enhanced DMA (EDMA) Controller User's Guide describes
the operation of the enhanced direct memory access (EDMA3) controller in the
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.
SPRUEL4 — TMS320DM647/DM648 DSP Peripheral Component Interconnect (PCI) User's Guide
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.
SPRUEL5 — 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.
SPRUEL8 — 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.
SPRUEM1 — 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 channel interface (TCI) 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 TCI mode, the VIC port is used to control the system clock, VCXO, for MPEG
transport channel.
