Overview
The TMS320C6743CPTPT2 is a low-power digital signal processor (DSP) from Texas Instruments, based on the C674x DSP core. This device is designed to offer high processing performance while consuming significantly lower power compared to other members of the TMS320C6000™ platform. It is particularly suited for original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly develop and market devices requiring advanced signal processing capabilities.
The C6743 DSP features 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 cache that can be configured as mapped memory, cache, or a combination of both. This architecture enhances the device's performance and efficiency in handling complex signal processing tasks.
