1.2Description

The C64x+™ DSPs (including the SM320C6455-EP device) are the highest-performance fixed-point DSP generation in the C6000™ DSP platform. The C6455 device is based on the third-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSPs an excellent choice for applications including video and telecom infrastructure, imaging/medical, and wireless infrastructure (WI). The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™ DSP platform.

Based on 90-nm process technology and with performance of up to 9600 million instructions per second (MIPS) [or 9600 16 bit MMACs per cycle] at a 1.2-GHz clock rate, the C6455 device offers cost-effective solutions to high-performance DSP programming challenges. The C6455 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors.
