ZHCSGV3G June 2009 – January 2017 TMS320C6748
PRODUCTION DATA.
The C674x core uses a two-level cache-based architecture. The Level 1 Program cache (L1P) is 32 KB direct mapped cache and the Level 1 Data cache (L1D) is 32 KB 2-way set associated cache. The Level 2 memory/cache (L2) consists of a 256 KB memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or a combination of both.
Table 3-2 shows a memory map of the C674x CPU cache registers for the device.
