Overview
The Texas Instruments TMS320C6743CPTPT3 is a low-power digital signal processor (DSP) 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 direct mapped Level 1 program cache (L1P) and a 32-KB 2-way set-associative Level 1 data cache (L1D). The Level 2 program cache (L2P) consists of 128-KB of memory space shared between program and data space, configurable as mapped memory, cache, or combinations of the two.
