clock cycles, the number of bus reads, and the number of bus writes required
for a table search. An RMC cycle to set the U bit is counted as one read and
The table is calculated based on the following assumptions:
Each entry in the table consists of three numbers that give the number of
one write. The format of the entires is:
2. There are no indirect descriptors,
3. There are no page descriptors encountered unexpectedly (no early
4. The memory port is 32 bits wide.
