Functions for the data cache. | |
Cortex-M7 processors include a memory system, which includes an optional MPU and Harvard data and instruction cache with ECC. The optional CPU cache has an instruction and data cache with sizes of [0;4;8;16;32;64]KB. Both instruction and data cache RAM can be configured at implementation time to have Error Correcting Code (ECC) to protect the data stored in the memory from errors.
All cache maintenance operations are executed by writing to registers in the memory mapped System Control Space (SCS) region of the internal PPB memory space.
The functions are grouped for:
