There are two levels of on-chip cache : a virtually indexed, physically tagged split I/D-L1, and a unified physically-addressed L2. The TLB is hardware-loaded from a two-level page table (PT) with 32-bit entries. TLB entries are tagged with an 8-bit address-space ID (ASID). Supported page sizes are 4KiB, 64KiB and 1 MiB. I/O is memory-mapped
