Low power and high precision with TMS320C674x DSPs

Developers now have the ability to bring portability to audio, medical, industrial and other applications requiring the precision, wide dynamic range and time-to-market benefits of floating-point DSPs. Using one-third the power of existing floating-point DSPs, C674x devices support 32-bit single-precision and 64-bit double-precision floating-point arithmetic and are the industry's lowest power floating-point DSPs. Power consumption ranges from 6 mW* in deep sleep mode to 420 mW† total power in active mode.
