The TMS320C67x DSPs (including the TMS320C6711, TMS320C6711B, TMS320C6711C, TMS320C6711D
devices) compose the floating-point DSP family in the TMS320C6000 DSP platform. The C6711, C6711B, C6711C, and C6711D 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 1200 million floating-point operations per second (MFLOPS) at a clock rate of 200 MHz or up to 1500 MFLOPS at a clock rate of 250 MHz, the C6711D device also offers cost-effective solutions to high-performance DSP programming challenges. The C6711D 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 C6711D can produce two MACs per cycle for a total of 400 MMACS.
The C6711D DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals.
The C6711D device 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, a host-port interface (HPI), and a glueless external memory interface (EMIF) capable of interfacing to SDRAM, SBSRAM and asynchronous peripherals.
The C6711D 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.
