Digital Media Processor
SPRS344C – NOVEMBER 2006 – REVISED JUNE 2008
The peripheral set includes: a configurable video port (VPFE); a 10/100 Mb/s Ethernet MAC (EMAC) with
a management data input/output (MDIO) module; a 4-bit transmit, 4-bit receive VLYNQ interface; an
inter-integrated circuit (I2C) Bus interface; a multichannel buffered serial port (McBSP); a multichannel
audio serial port (McASP0) with 4 serializers; 2 64-bit general-purpose timers each configurable as
2 independent 32-bit timers; 1 64-bit watchdog timer; a user-configurable 16-bit host-port interface (HPI);
up to 111-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation
modes, multiplexed with other peripherals; 2 UARTs with hardware handshaking support on 1 UART;
3 pulse width modulator (PWM) peripherals; 1 high-end controller area network (CAN) controller [HECC];
and 2 glueless external memory interfaces: an asynchronous external memory interface (EMIFA) for
slower memories/peripherals, and a higher speed synchronous memory interface for DDR2.
The DM6435 device includes a Video Processing Subsystem (VPSS) with a configurable video/imaging
front-end input peripheral used for video capture.
The Video Processing Front-End (VPFE) is comprised of a CCD Controller (CCDC), a Preview Engine
(Previewer), Histogram Module, Auto-Exposure/White Balance/Focus Module (H3A), and Resizer. The
CCDC is capable of interfacing to common video decoders, CMOS sensors, and Charge Coupled Devices
(CCDs). The Previewer is a real-time image processing engine that takes raw imager data from a CMOS
sensor or CCD and converts from an RGB Bayer Pattern to YUV422. The Histogram and H3A modules
provide statistical information on the raw color data for use by the DM6435. The Resizer accepts image
data for separate horizontal and vertical resizing from 1/4x to 4x in increments of 256/N, where N is
between 64 and 1024.
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM6435 and
the network. The DM6435 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps)
and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS)
support.
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The I2C and VLYNQ ports allow DM6435 to easily control peripheral devices and/or communicate with
host processors.
The high-end controller area network (CAN) controller [HECC] module provides a network protocol in a
harsh environment to communicate serially with other controllers, typically in automotive applications.
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 later in this document
and the associated peripheral reference guides.
The DM6435 has a complete set of development tools. These include C compilers, a DSP assembly
optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into
source code execution.
