Question: Assume the following: The memory is byte addressable. Memory accesses are to 1 - byte words ( not to 4 - byte words ) .
Assume the following:
The memory is byte addressable.
Memory accesses are to byte words not to byte words
Virtual addresses are bits wide.
Physical addresses are bits wide.
The page size is bytes.
The TLB is way associative tlb with sets and a total of entries
The TLB and a portion of the page table contents are as shown below
Assume that memory address xc has been referenced by a load instruction. Determine the virtual page number VPN and use that to compute the TLB index
and tag that would be used to check the TLB for the translation entry. Indicate if the entry is in the TLB YN
Indicate if the memory reference has a valid entry in the page table whether it hits in the TLB or not.
Use the information from the page table to translate the VPN to a physical page number PPN and then the valid physical address PA
For entries that can not be determined eg the PPN or PA if a translation doesn't exist enter
