C674x DSP Subsystem

High Definition Video Image Co-Processors

Memory Management Units (MMU)

The device contains these memory management units (MMU):

Enhanced DMA controller (EDMA)

On-chip Enhanced DMA controller (EDMA) supports 4 simultaneous physical channels and up to 64 programmable logical channels

Interrupt Controller (INTC)

The device has one interrupt controller (INTC) module.

General-Purpose Memory Controller (GPMC)

SDRAM

On-Chip Memory Controller (OCMC) Subsystem

128K-Byte of general purpose OCMC (On-chip memory controller) RAM

SGX530™ Graphics Accelerator - Only in DM8148

The SGX530™ Graphics Accelerator subsystem accelerates 3-dimensional (3D) graphics applications. The SGX subsystem is based on the core from Imagination Technologies.

HD Video Processing Subsystem (HDVPSS)

Provides high quality display processing, digital video inputs and outputs, HDMI 1.3 transmit, and simultaneous HD/SD analog output with OSD. Refer to the device datasheet and TRM for more details on HDVPSS features.

HDVICP2

Timers

The device includes several types of timers used by the system software, including 8 general-purpose timers (GP timers) and one watchdog timers (WDT).

UART/IrDA/CIR Overview

The processor contains six Configurable UART/IrDA/CIR Modules

Inter-Integrated Circuit (I2C) Module

The device contains four Inter-Integrated Circuit (I2C Bus™) Ports.

McSPI

The multichannel serial port interface (McSPI) is a master/slave synchronous serial bus. There is four Serial Peripheral Interfaces (SPIs) [up to 48-MHz]

McBSP

The multi-channel buffered serial port (McBSP) provides a full-duplex direct serial interface between the device and other devices in a system such as other application chips (digital base band), audio and voice codec (AIC23 device), etc. Because of its high level of versatility, it can accommodate to a wide range of peripherals and clocked frame oriented protocols.

The device provides one instance of the McBSP module.

McASP

The multichannel audio serial port (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 similar formats

Secure Digital/Secure Digital I/O (SD/SDIO) Card Interface

The processor contains three MMC/SD/SDIO Serial Interfaces [up to 48-MHz]

Universal Serial Bus (USB)

The device includes two USB ports with integrated 2.0 PHY.

General Purpose I/O (GPIO) Interface

The general-purpose interface combines six general-purpose input/output (GPIO) banks.

The device contains four GPIO modules and each GPIO module is made up of 32 identical channels.

These pins can be configured for the following applications:

transition(s) and/or signal level(s)).

Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module

The EMAC controls the flow of packet data from the system to the PHY. The MDIO module controls PHY configuration and status monitoring.

Both the EMAC and the MDIO modules interface to the system core through a custom interface that allows efficient data transmission and reception. This custom interface is referred to as the EMAC subsystem module and is considered integral to the EMAC/MDIO peripheral.

The EMAC module is used to move data between the device and another host connected to the same network, in compliance with the Ethernet protocol.

We probably shouldn't have links to internal forums om an external wiki page.

The DM814x Technical Reference manual link is broken under Important Documentation.

I found the correct link here: http://processors.wiki.ti.com/index.php/Device:DM814x:Device_Evaluation

The correct link would be: http://www.ti.com/lit/pdf/sprugz8
