Description

The TMS320C67x™ DSPs (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 C6712C device is the lowest-cost DSP in the C6000™ DSP platform. The C6712C 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 C6712C can produce two MACs per cycle for a total of 300 MMACS.

With performance of up to 600 million floating-point operations per second (MFLOPS) at a clock rate of 100 MHz, the C6712 device also offers cost-effective solutions to high-performance DSP programming challenges. The C6712 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 C6712 can produce two multiply-accumulates (MACs) per cycle for a total of 200 million MACs per second (MMACS).

The C6712/C6712C 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 C6712C device also includes a dedicated general-purpose input/output (GPIO) peripheral module.

The C6712/C6712C DSPs also have application-specific hardware logic, on-chip memory, and additional on-chip peripherals.

The C6712/C6712C 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.
