Application designers now have the greatest range of price and performance options with floating-point digital signal processors (DSPs) from Texas Instruments. TMS320C67xTM DSPs are the industry's most powerful floating-point processors, and TMS320C3xTM DSPs provide incredible performance, precision and dynamic range. These processors are available at a number of price points so developers can select the device that best meets the needs of target applications.
The TI Floating-Point DSP Advantage TI floating-point DSPs raise the bar in performance, set new levels in cost efficiency, and offer low power dissipation--energizing existing products and supporting the development of next-generation applications. Several features of TI's floating-point DSPs make them attractive for applications that require a larger dynamic range and a higher level of precision than offered by typical 16-bit fixed-point devices. For example, a 32-bit
word-width enables high fidelity audio systems to produce more life-like sound. Graphics and imaging systems need the full 32-bits to achieve greater resolution and more realistic visuals. In addition, the DSPs' substantial processing power provides higher frame rates and additional polygon manipulations that further enhance image sharpness and quality. Motion control, automotive, robotics, instrumentation, military and voice/speech applications similarly benefit from the extra precision and high performance of TI floating-point DSPs.
TI provides application designers the largest assortment of DSP floating-point price and performance options. TI leads the way in floating-point DSP technology and continues to build on its leadership position--as it has for more than 12 years.
Unparalleled Performance with VelociTI TM Architecture All TMS320C6000TM DSPs are based on the same CPU core, featuring VelociTITM, an advanced very long instruction word (VLIW) architecture designed to achieve high performance through increased instructionlevel parallelism. TI achieves breakthrough performance by adding floating-point instructions to six of the C6000 DSP architecture's eight functional units. The eight functional units, including two multipliers and six arithmetic units, are highly orthogonal, providing the
compiler and Assembly Optimizer with many execution resources. Eight 32-bit RISClike instructions are fetched by the CPU each cycle. The VelociTI instruction packing features allow these eight instructions to be executed in parallel, in serial, or in parallel/serial combinations. This optimized scheme enables significant reductions in code size, program fetches and power consumption. Unified Architecture Provides Code Compatibility With the same VelociTITM core, TI's C67xTM DSPs are code and
pin-for-pin compatible with C62xTM fixed-point DSPs. The C67x DSP instruction set is a superset of that for the C62x devices. This allows developers to take advantage of the ease-of-use of floating-point by prototyping on the C6711 DSP, and then porting their code to the fixed-point C6211 DSP for reduced production costs. Together with the ease of a single development platform, this code-transfer capability between fixedand floating-point DSPs results in significant savings in development, resource and manufacturing costs.
