Product details
Overview
TMS320DM642AZDK6 from Texas Instruments is a fixed-point digital signal processor (DSP) optimized for video and imaging applications, featuring a 720-MHz C64x™ DSP core delivering 5760 MIPS, 256KB L2 unified RAM/cache, three configurable video ports supporting ITU-R BT.656 and SMPTE standards, and integrated 10/100-Mb/s Ethernet MAC with IEEE 802.3 compliance - deployed in professional IP video encoders and broadcast infrastructure equipment.
For engineers reviewing the TMS320DM642AZDK6 datasheet, TMS320DM642AZDK6 pinout, TMS320DM642AZDK6 application, or TMS320DM642AZDK6 equivalent, key selection considerations include its 548-pin ZDK BGA package (0.8-mm pitch), 3.3-V I/O / 1.4-V core voltage, EDMA controller with 64 independent channels, McASP0 supporting S/PDIF and AES-3 audio encoding, and PCI 2.2-compliant 32-bit/66-MHz interface for system expansion.
Technical Context
The TMS320DM642AZDK6 implements the VelociTI.2™ VLIW architecture with eight functional units (six ALUs, two multipliers), enabling four 16×16-bit or eight 8×8-bit MACs per cycle. Its dual-register-file CPU supports 64 general-purpose 32-bit registers and non-aligned load/store operations across byte, half-word, word, and doubleword boundaries.
Memory subsystem includes 16KB L1P direct-mapped cache, 16KB L1D 2-way set-associative cache, and 256KB L2 unified memory configurable as RAM, cache, or mixed allocation. Peripherals are tightly coupled via dedicated buses: EMIFA provides glueless 64-bit interface to SDRAM, ZBT SRAM, and FIFOs; EMAC uses custom DMA path for zero-copy packet handling; and VP0/VP1/VP2 each support dual-channel capture/display with 5120-byte buffers.

FAQ
What is the maximum operating frequency of the TMS320DM642AZDK6?
The TMS320DM642AZDK6 operates at a maximum clock rate of 720 MHz, achieving 5760 million instructions per second (MIPS) and 5760 million multiply-accumulates per second (MMACS) for 8×8-bit operations. This frequency is enabled by its 0.13-µm CMOS process and 1.4-V core supply, and is validated across the full industrial temperature range per TI's SPRS200N datasheet revision October 2010.
Does the TMS320DM642AZDK6 support IEEE 802.3 Ethernet communication?
Yes, the TMS320DM642AZDK6 integrates a fully compliant 10/100-Mb/s Ethernet MAC (EMAC) supporting both 10Base-T and 100Base-TX in half- and full-duplex modes, along with hardware flow control and QoS features. It implements the Media Independent Interface (MII) and includes an integrated MDIO module for PHY management - all confirmed in Section 5.16 of the official datasheet.
How many video ports does the TMS320DM642AZDK6 include, and what standards do they support?
The TMS320DM642AZDK6 includes three fully configurable video ports (VP0, VP1, VP2), each supporting dual-channel capture and display with 5120-byte buffers. These ports provide glueless interface to standard video codecs and support ITU-R BT.656, CCIR601, SMPTE 125M/260M/274M/296M, and BT.1120 formats - as detailed in Sections 5.14 and 2.1 of the SPRS200N datasheet.
What is the memory architecture of the TMS320DM642AZDK6?
The TMS320DM642AZDK6 features a two-level cache-based memory architecture: 16KB L1P direct-mapped program cache, 16KB L1D 2-way set-associative data cache, and 256KB L2 unified memory that can be flexibly allocated as RAM, cache, or a combination. This structure is documented in Section 2.3 and Figure 1-1 of the SPRS200N datasheet and enables efficient video frame buffering and algorithm execution.
Is the TMS320DM642AZDK6 pin-compatible with other C64x™ DSPs like the TMS320DM6437?
No, the TMS320DM642AZDK6 is not pin-compatible with the TMS320DM6437. The TMS320DM642AZDK6 uses a 548-pin ZDK BGA package (0.8-mm pitch), whereas the DM6437 uses a 361-pin BGA. Peripheral sets also differ significantly: the DM642 includes PCI, three video ports, and dual McASP channels, while the DM6437 omits PCI and reduces video I/O - confirmed in TI's SPRU615 technical overview.
