Texas Instruments TMS320C6748 Fixed & Floating-Point DSP
Texas Instruments TMS320C6748 Fixed and Floating-Point DSP is a low-power applications processor based on a C674x DSP core. This DSP provides significantly lower power than other members of the TMS320C6000™ platform of DSPs. The device enables original-equipment manufacturers (OEMs) and original design manufacturers (ODMs) to bring to market devices quickly. These devices come with robust operating systems, rich user interfaces, and high processor performance through the maximum flexibility of a fully integrated, mixed-processor solution.
