description
The TMS320C67x DSP (including the TMS320C6712, TMS320C6712C, TMS320C6712D devices
†
) are
members of the floating-point DSP family in the TMS320C6000 DSP platform. The C6712, C6712C, and
C6712D devices are based on the high-performance, advanced very-long-instruction-word (VLIW) architecture
developed by Texas Instruments (TI), making these DSPs an excellent choice for multichannel and multifunction
applications.
With performance of up to 900 million floating-point operations per second (MFLOPS) at a clock rate of
150 MHz, the C6712D device is the lowest-cost DSP in the C6000 DSP platform. The C6712D DSP
possesses the operational flexibility of high-speed controllers and the numerical capability of array processors.
This processor has 32 general-purpose registers of 32-bit word length and eight highly independent functional
units. The eight functional units provide four floating-/fixed-point ALUs, two fixed-point ALUs, and two
floating-/fixed-point multipliers. The C6712D can produce two MACs per cycle for a total of 300 MMACS.
The C6712D uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The
Level 1 program cache (L1P) is a 32-Kbit direct mapped cache and the Level 1 data cache (L1D) is a 32-Kbit
2-way set-associative cache. The Level 2 memory/cache (L2) consists of a 512-Kbit 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 two multichannel buffered serial ports (McBSPs), two
general-purpose timers, and a glueless 16-bit external memory interface (EMIF) capable of interfacing to
SDRAM, SBSRAM, and asynchronous peripherals. The C6712D device also includes a dedicated
general-purpose input/output (GPIO) peripheral module.
The C6712D DSP also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals.
The C6712D 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.
