TMS320DM643

Video/Imaging Fixed-Point Digital Signal Processor

SPRS269A – FEBRUARY 2005 – REVISED APRIL 2005

The VCXO interpolated control (VIC) port provides digital-to-analog conversion with resolution from 9-bits

to up to 16-bits. The output of the VIC is a single bit interpolated D/A output.For more details on the VIC

port, see the TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide

(literature number SPRU629).

The ethernet media access controller (EMAC) provides an efficient interface between the DM643 DSP

core processor and the network. The DM643 EMAC support both 10Base-T and 100Base-TX, or

10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex, with hardware flow control and quality

of service (QOS) support. The DM643 EMAC makes use of a custom interface to the DSP core that

allows efficient data transmission and reception.For more details on the EMAC, see the TMS320C6000

DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO) Module

Reference Guide (literature number SPRU628).

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 DSP, 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 DSP, allowing the DSP to poll the link

status of the device without continuously performing costly MDIO accesses. For more details on the

MDIO, see the TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data

Input/Output (MDIO) Module Reference Guide (literature number SPRU628).

The I2C0 port on the TMS320DM643 allows the DSP to easily control peripheral devices and

communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP)

may be used to communicate with serial peripheral interface (SPI) mode peripheral devices.

The DM643 has a complete set of development tools which includes: a new C compiler, an assembly

optimizer to simplify programming and scheduling, and a Windows

® debugger interface for visibility into

source code execution.

The DM643 device is a code-compatible member of the C6000™ DSP platform.

The C64x™ DSP generation of devices has a diverse and powerful set of peripherals.

For more detailed information on the device compatibility and similarities/differences among the DM642

and other C64x™ devices, see the TMS320DM642 Technical Overview (literature number SPRU615).
