Overview
The TMS320C6711DGDP250 is a high-performance floating-point Digital Signal Processor (DSP) from Texas Instruments, part of the TMS320C6000 DSP platform. This device is based on the advanced very-long-instruction-word (VLIW) architecture, making it an excellent choice for multichannel and multifunction applications. The C6711D offers significant performance with up to 1200 million floating-point operations per second (MFLOPS) at 200 MHz and up to 1500 MFLOPS at 250 MHz, providing cost-effective solutions to high-performance DSP programming challenges.
The processor combines the operational flexibility of high-speed controllers and the numerical capability of array processors, featuring 32 general-purpose registers and eight highly independent functional units. These units include four floating-/fixed-point ALUs, two fixed-point ALUs, and two floating-/fixed-point multipliers, enabling the production of two MACs per cycle for a total of 400 MMACS.
