4 Gbytes of physical address space, 256 address spaces (identified by
an 8-bit ASID (address space identifier))
Supports single virtual memory mode and multiple virtual memory mode
Supports multiple page sizes: 1 kbyte, 4 kbytes, 64 kbytes, or 1 Mbytes
4-entry full associative TLB for instructions
64-entry full associative TLB for instructions and operands
Supports software-controlled replacement and random-counter
replacement algorithms
Contents of TLB are directly accessible through address mapping
