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-purpose64-bit timer, dual general-purpose32-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-speedpoint-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.
