1.2 Description
The TMS320DM6467T (also referenced as DM6467T) leverages TI’s DaVinci™ technology to meet the
networked media encode and decode digital media processing needs of next-generation embedded
devices.
The DM6467T enables OEMs and ODMs to quickly bring to market devices featuring robust operating
systems support, rich user interfaces, high processing performance, and long battery life through the
maximum flexibility of a fully integrated mixed processor solution.
The dual-core architecture of the DM6467T provides benefits of both DSP and Reduced Instruction Set
Computer (RISC) technologies, incorporating a high-performance TMS320C64x+ DSP core and an
ARM926EJ-S core.
The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and
processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and
memory system can operate continuously.
The ARM core incorporates:
A coprocessor 15 (CP15) and protection module
Data and program Memory Management Units (MMUs) with table look-aside buffers.
Separate 16K-byte instruction and 8K-byte data caches. Both are four-way associative with virtual
index virtual tag (VIVT).
The TMS320C64x+™ DSPs are the highest-performance fixed-point DSP generation in the
TMS320C6000™ DSP platform. It is based on an enhanced version of the second-generation high-
performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments
(TI), making these DSP cores an excellent choice for digital media applications. The C64x is a code-
compatible member of the C6000™ DSP platform. The TMS320C64x+ DSP is an enhancement of the
C64x+ DSP with added functionality and an expanded instruction set.
Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and
C64x+ CPU, respectively.
With performance of up to 8000 million instructions per second (MIPS) at a clock rate of 1 GHz, the C64x+
core offers solutions to high-performance DSP programming challenges. The DSP core possesses the
operational flexibility of high-speed controllers and the numerical capability of array processors. The
C64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly
independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs). The
eight functional units include instructions to accelerate the performance in video and imaging applications.
The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 4000 million
MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 8000 MMACS. For more details
on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide
(literature number SPRU732).
The DM6467T also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals similar to the other C6000 DSP platform devices. The DM6467T core uses a two-level cache-
based architecture. The Level 1 program cache (L1P) is a 256K-bit direct mapped cache and the Level 1
data cache (L1D) is a 640K-bit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of
an 512K-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: a configurable video port; a 10/100/1000 Mb/s Ethernet MAC (EMAC) with a
Management Data Input/Output (MDIO) module; a 4-bit transfer/4-bit receive VLYNQ interface; an inter-
integrated circuit (I2C) Bus interface; a multichannel audio serial port (McASP0) with 4 serializers; a
secondary multichannel audio serial port (McASP1) with a single transmit serializer; 2 64-bit general-
purpose timers each configurable as 2 independent 32-bit timers; 1 64-bit watchdog timer; a configurable
32-bit host port interface (HPI); up to 33-pins of general-purpose input/output (GPIO) with programmable
