The
highest-performance
DM647/DM648 devices are based on the third-generation high-performance, advanced VelociTI
very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSPs
an excellent choice for digital media applications. The C64x+ devices are upward code-compatible from
previous devices that are part of the C6000 DSP platform. The C64x DSPs support added
functionality and have an expanded instruction set from previous devices.

platform.
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 7200 million instructions per second (MIPS) at a clock rate of 900 MHz, 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 2400 million
MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4800 MMACS. For more details
on the C64x+ DSP, see the
TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide
(literature number
SPRU732
).
The DM647/DM648 devices also have application-specific hardware logic, on-chip memory, and additional
on-chip peripherals similar to the other C6000 DSP platform devices. The DM647/DM648 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 256K-bit 2-way set-associative cache. The Level 2 memory/cache
(L2) consists of a 4M-bit (DM648) or 2M-bit (DM647) 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: The DM647/DM648 devices have five configurable 16-bit video port
peripherals (VP0, VP1, VP2, VP3, and VP4). These video port peripherals provide a glueless interface to
common video decoder and encoder devices. The DM647/DM648 video port peripherals support multiple
resolutions and video standards (e.g., CCIR601, ITU-BT.656, BT.1120, SMPTE 125M, 260M, 274M, and
296M), a VCXO interpolated control port (VIC); a 1000 Mbps 3-port switch with a management data
input/output (MDIO) module and two SGMII ports (DM648 only); an 1000 Mbps Ethernet media access
controller (EMAC) and a management data input/output (MDIO) module (only DM647); a 4-bit transmit,
