Section 5 Cache
5.3.2
Read Hit: In a read access, instructions and data are transferred from the cache to the CPU. The
LRU is updated.
Read Miss: An external bus cycle starts and the entry is updated. The way replaced is shown in
table 5.3. Entries are updated in 16-byte units. When the desired instruction or data that caused the
miss is loaded from external memory to the cache, the instruction or data is transferred to the CPU
in parallel with being loaded to the cache. When it is loaded in the cache, the U bit is cleared to 0
and the V bit is set to 1.
