The DM6443 includes a Video Processing Sub-System (VPSS) that has a configurable Resizer and Video
Processing Back-End (VPBE) output used for display.
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 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 DM644X MPU
core processor and the network. The DM6443 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. Once a PHY candidate has been selected by the MPU, the
MDIO module transparently monitors its link state by reading the PHY status register. Link change events
are stored in the MDIO module and can optionally interrupt the MPU, allowing the MPU to poll the link
status of the device without continuously performing costly MDIO accesses.
The I2C, SPI, USB2.0, and VLYNQ ports allow DM6443 to easily control peripheral devices and/or
communicate with host processors.
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 DM6443 has a complete set of development tools for both the ARM and DSP. These include C
compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™
debugger interface for visibility into source code execution.
