Product Introduction

Overview

The TMS320C6746 fixed- and floating-point DSP, produced by Texas Instruments, is a low-power applications processor based on the C674x DSP core. This device is designed to provide significantly lower power consumption compared to other members of the TMS320C6000™ platform of DSPs. It enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly bring to market devices with robust operating systems, rich user interfaces, and high processor performance through a fully integrated, mixed processor solution.
