Overview
The TMS320C6745DPTPD4 is a low-power digital signal processor (DSP) from Texas Instruments, based on the TMS320C674x DSP core. This device is part of the TMS320C6000™ platform and is designed to consume significantly lower power compared to other members of this family. It is ideal for original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) who need to quickly bring to market devices with high processing performance.
The TMS320C6745/6747 devices feature a two-level cache-based architecture, including 32KB of L1P program cache, 32KB of L1D data cache, and 256KB of L2 unified mapped RAM/cache. This architecture, along with the enhanced direct memory access controller 3 (EDMA3), supports high-performance data processing and efficient memory management.
