4-Gbyte address space, 256 address space identifiers (8-bit ASID)
Supports single virtual memory mode and multiple virtual memory mode
Multiple page sizes: 1, 4, 8, 64, or 256 Kbytes, or 1, 4, or 64 Mbytes
4-entry fully associative TLB for instructions
64-entry fully associative TLB for instructions and operands
Selection of software-driven or random-counter replacement algorithms
The TLB is address-mapped, making its contents directly accessible.
