5.3 Processor Exceptions
TLB Exceptions
Three types of TLB exceptions can occur:
- TLB Refill occurs when there is no TLB entry that matches an attempted reference to a mapped address space.
- TLB Invalid occurs when a virtual address reference matches a TLB entry that is marked invalid.
- TLB Modified occurs when a store operation virtual address reference to memory matches a TLB entry which is marked valid but is not dirty (the entry is not writable).
The following three sections describe these TLB exceptions.
