The Video Processing Back-End (VPBE) is comprised of an On-Screen Display Engine (OSD) and a

Video Encoder (VENC). The OSD engine is capable of handling 2 separate video windows and 2 separate

OSD windows. Other configurations include 2 video windows, 1 OSD window, and 1 attribute window

allowing up to 8 levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz,

providing a means for composite NTSC/PAL video, S-Video, and/or Component video output. The VENC

also provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of

8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs.

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM6437 and

the network. The DM6437 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 DM6437 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 DM6437 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.
