Section 5 Cache
5.5
5.5.1
Specific cache entries can be invalidated by writing 0 to the entry’s V bit. When the A bit is 1, the
address tag specified by the write data is compared to the address tag within the cache selected by
the entry address, and data is written when a match is found. If no match is found, there is no
operation. R0 specifies the write data in R0 and R1 specifies the address. When the V bit of an
entry in the address array is set to 0, the entry is written back if the entry’s U bit is 1.
5.5.2
This example reads the data section of a specific cache entry. The longword indicated in the data
field of the data array in figure 5.6 is read to the register. R0 specifies the address and R1 is read.
