cache line.
Same as cache block. In this chapter, cache line is used for cache block.
cache miss.
A memory access that does not match any valid entry in the cache.
direct mapped.
Cache architecture in which each line has only one place in which it can
appear in the cache. Also described as 1-Way associative.
dirty (or modified).
A state bit, stored along with the tag, indicating whether the data in the
data cache line has been changed since it was copied from the source
memory and, therefore, needs to be updated in that source memory.
exclusive, clean.
The state of a data cache line, indicating that the line is valid and that the
data contained in the line matches that in the source memory. The data in
a clean cache line does not need to be written to source memory before it
is replaced.
fully associative.
Cache architecture in which each line can be placed anywhere in the
cache.
index.
Address portion that is used to select an array element (for example, a line
index).
invalid.
Describes the state of a cache line. When a cache line is invalid, a cache
line match cannot occur.
