cache
/kash/ A small fast memory holding
recently accessed data, designed to speed up subsequent access
to the same data. Most often applied to processor-memory
access but also used for a local copy of data accessible over
a network etc.
When data is read from, or written to, main memory a copy is
also saved in the cache, along with the associated main memory
address. The cache monitors addresses of subsequent reads to
see if the required data is already in the cache. If it is (a
cache hit) then it is returned immediately and the main
memory read is aborted (or not started). If the data is not
cached (a cache miss) then it is fetched from main memory
and also saved in the cache.
The cache is built from faster memory chips than main memory
so a cache hit takes much less time to complete than a normal
memory access. The cache may be located on the same
integrated circuit as the CPU, in order to further reduce
the access time. In this case it is often known as primary
cache since there may be a larger, slower secondary cache
outside the CPU chip.
The most important characteristic of a cache is its hit rate
- the fraction of all memory accesses which are satisfied from
the cache. This in turn depends on the cache design but
mostly on its size relative to the main memory. The size is
limited by the cost of fast memory chips.
The hit rate also depends on the access pattern of the
particular program being run (the sequence of addresses being
read and written). Caches rely on two properties of the
access patterns of most programs: temporal locality - if
something is accessed once, it is likely to be accessed again
soon, and spatial locality - if one memory location is
accessed then nearby memory locations are also likely to be
accessed. In order to exploit spatial locality, caches often
