TMS320DM6437
Digital Media Processor
SPRS345B–NOVEMBER 2006–REVISED MARCH 2007
The DM6437 also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals similar to the other C6000 DSP platform devices. The DM6437 core uses a two-level
cache-based architecture. The Level 1 program memory/cache (L1P) consists of a 256K-bit memory
space that can be configured as mapped memory or direct mapped cache, and the Level 1 data (L1D)
consists of a 640K-bit memory space —384K-bit of which is mapped memory and 256K-bit of which can
be configured as mapped memory or 2-way set-associative cache. The Level 2 memory/cache (L2)
consists of a 1M-bit memory space that is shared between program and data space. L2 memory can be
configured as mapped memory, cache, or combinations of the two.
The peripheral set includes: 2 configurable video ports; 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; two multichannel buffered serial ports (McBSPs); 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]; 1
peripheral component interconnect (PCI) [33 MHz]; 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 DM6437 device includes a Video Processing Subsystem (VPSS) with two configurable video/imaging
peripherals: 1 Video Processing Front-End (VPFE) input used for video capture, 1 Video Processing
Back-End (VPBE) output.
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 DM6437. 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 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.
