Overview
The TMS320C6743BPTPT2 is a low-power digital signal processor (DSP) from Texas Instruments, based on the C674x DSP core. This device is designed to consume significantly lower power 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 featuring high processing performance. The C6743 DSP core utilizes a two-level cache-based architecture, including a 32-KB Level 1 program cache (L1P) and a 32-KB Level 1 data cache (L1D), along with a 128-KB Level 2 program cache (L2P) that can be configured as mapped memory, cache, or a combination of both.
