The TMS320C6748BZWTA3 is a Fixed/Floating Point Digital Signal Processor, low-power applications processor based on a C674x DSP core. This DSP provides significantly lower power than other members of the TMS320C6000™ platform of DSPs. The device enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly bring to market devices with robust operating systems, rich user interfaces and high processor performance through the maximum flexibility of a fully integrated, mixed processor solution. The device DSP core uses a 2-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 memory can be configured as mapped memory, cache or combinations of the two.
