located in the last 4 Mbytes of the KSEG1 non-cacheable region of memory. The core enters kernel mode both at reset and when an exception is recognized, hence able to map the virtual address to physical address. The reset vector for the ARM family of processors is address 0x0 or 0xFFFF0000. During normal execution RAM is re-mapped to this location to improve performance, compared to the original ROM-based vector table.
