TMS320C6746 定点/浮点数字信号处理器
The C6745/6747 is a Low-power applications processor based on C674x™ DSP core. It consumes significantly lower power than other members of the TMS320C6000™ platform of DSPs.
The C6745/6747 enables OEMs and ODMs to quickly bring to market devices featuring high processing performance.
The C6745/6747 DSP core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 32KB direct mapped cache and the Level 1 data cache (L1D) is a 32KB 2-way set-associative cache. The Level 2 program cache (L2P) consists of a 256KB memory space that is shared between program and data space. L2 also has a 1024KB ROM. L2 memory can be configured as mapped memory, cache, or combinations of the two
