Preliminary
6.14: VIMEM Last Processor Read Real Address
This register provides information to the user about the last read access of virtual Packet Memory by the pro-
cessor. If a virtual address was accessed, this register contains the real address generated by the Virtual
Memory logic that can be used to access the same location. This register is intended mainly as an aid in
debugging to make virtual address translation easier. To perform the translation, the processor must read
from the desired virtual address: after the read is complete, this register contains the real address that was
accessed. The address contained in this register is an offset from the beginning of physical Packet Memory.
