The following notation is used in connection with translation from virtual to physical addresses:

Address	Cache
virtual	TLB

VPN	Virtual page number
VPO	Virtual page offset (in bytes)
TLBI	TLBI index

After translating the virtual address to a physical address, another cache is checked to see if it contains the memory contents of the physical address. This notation is used:

Address	Cache
physical	L1

(physical adddresses)
PPN	physical page number
PPO	physical page offset (PPO = VPO)
CI	Cache index
CO	Byte offset in cache block
CT	Cache tag
