4 / 231 page www.ti.com TMS320DM6446 Digital Media System-on-Chip SPRS283E – DECEMBER 2005 – REVISED MARCH 2007 The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM644x and the network. The DM6446 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 ARM, 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 ARM, allowing the ARM to poll the link status of the device without continuously performing costly MDIO accesses. The HPI, I2C, SPI, USB2.0, and VLYNQ ports allow DM6446 to easily control peripheral devices and/or communicate with host processors. The DM6446 also provides multimedia card support, MMC/SD, with SDIO support. The DM6446 also includes a Video/Imaging Co-processor (VICP) to offload many video and imaging processing tasks from the DSP core, making more DSP MIPS available for common video and imaging algorithms. For more information on the VICP enhanced codecs, such as H.264 and MPEG4, please contact your nearest TI sales representative. 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 DM6446 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.
