TMS320C674x Low Power DSPs

 
TMS320C674x Fixed/Floating-Point DSPs

Combines the fixed-point C64x+™ instruction set and the floating-point C67x+™ instruction set to bring floating-point precision and fixed-point performance to energy-efficient, connected applications 100 percent upward code compatible with devices based on the TMS320C6000™ fixed- and floating-point cores to preserve code investments.

  • Industry’s lowest power floating-point DSPs
  • Makes portability possible traditionally wired applications through low power and rich connectivity peripherals
  • Reduces system cost through high feature integration and low pricing starting
    • at less than $10 @ 100u quantities
  • 20X lower standby power and 1/3 the power consumption of existing floating-point devices
C674x DSP Applications
  • Music effects
  • Industrial
  • Conference phones
  • Portable medical
  • Audio conferencing
  • Power protection systems
  • Industrial monitoring
