Overview
The TMS320C6748BZCEA3E is a fixed- and floating-point Digital Signal Processor (DSP) from Texas Instruments, based on the C674x DSP core. This low-power applications processor is designed to provide high performance with significantly lower power consumption compared to other members of the TMS320C6000 platform. It enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly develop devices with robust operating systems, rich user interfaces, and high processor performance through a fully integrated, mixed processor solution. The device uses a 2-level cache-based architecture, enhancing its efficiency and performance.
