Memory Management Unit
The example bus error exception routine is called BusErrorHandler. It is more general than
Vallocate because it relies on several operating-system-dependent items. The variable
pointer VictimTask is assumed to point to a table from a task that is losing a page frame.
This assumption is necessary because control block layout and the method of searching for
and finding other tasks in the example operating system are not defined. The code is further
simplified by omitting the function code value and the read/write status, which do not affect
the basic logic of the program.
