Description

TMS320DM814x DaVinci video processors are highly integrated, programmable platforms that leverage

the DaVinci processor technology to meet the processing needs of the following applications to name a

few:

•

HD Video Conferencing - Skype endpoints

•

Video Surveillance DVRs

•

IP Netcam

•

Digital Signage

•

Media Players and Adapters

•

Mobile Medical Imaging

•

Network Projectors

•

Home Audio and Video Equipment

The device enables Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers

(ODMs) to quickly bring to market devices featuring robust operating systems support, rich user interfaces,

and high processing performance through the maximum flexibility of a fully integrated mixed processor

solution. The device also combines programmable video and audio processing with a highly integrated

peripheral set.

The TMS320DM814x DaVinci video processors also present OEMs and ODMs with new levels of

processor scalability and software reuse. An OEM or ODM that used the AM387x processors in a design

and can make a similar product with added features could scale up to the pin-compatible and software-

compatible TMS320DM814x processors from TI. The TMS320DM814x DaVinci video processors add a

powerful C674x DSP core along with a video encoder and decoder to the hardware on the AM38x.

Additionally, OEMs or ODMs that have used the AM387x or DM814x processors and find a need for a

faster ARM and DSP core performance could scale up to the software-compatible AM389x or

TMS320DM816x devices with higher core speeds.

Programmability is provided by an ARM Cortex-A8 RISC CPU with Neon extension, TI C674x VLIW

floating-point DSP core, and high-definition video and imaging coprocessors. The ARM lets developers

keep control functions separate from A/V algorithms programmed on the DSP and coprocessors, thus

reducing the complexity of the system software. The ARM Cortex-A8 32-Bit RISC Core with Neon floating-

point extension includes: 32KB of Instruction cache; 32KB of Data cache; 512KB of L2 Cache; 48KB of

Boot ROM; and 64KB of RAM.

The rich peripheral set provides the ability to control external peripheral devices and communicate with

external processors. For details on each of the peripherals, see the related sections in this document and

the associated peripheral reference guides. The peripheral set includes:

•

HD Video Processing Subsystem

•

Dual Port Gigabit Ethernet MACs (10/100/1000 Mbps) [Ethernet Switch] with MII/RMII/GMII/RGMII and

MDIO interface supporting IEEE 1588 Time-Stamping and Industrial Ethernet Protocols

•

Two USB ports with integrated 2.0 PHY

•

PCIe x1 GEN2 Compliant interface

•

Two 10-serializer McASP audio serial ports (with DIT mode)

•

Four quad-serilaizer McASP audio serial ports (with DIT mode)

•

One McBSP multichannel buffered serial port

•

Six UARTs with IrDA and CIR support

•

Four SPI serial interfaces

•

Three MMC/SD/SDIO serial interfaces

•

Four I2C master and slave interfaces

•

Parallel Camera Interface (CAM)

•

Up to 128 General-Purpose I/Os (GPIOs)

High-Performance System-on-Chip (SoC)
