What are level 1 cache and level 2 cache memories (i.e., L1 and L2 caches)?
What will be an ideal response?
In an ideal world, there would be no cache. Main memory, DRAM, would be fast enough. Cache memory is used to hide the DRAM latency. Unfortunately, cache is expensive and the size of the cache is limited (today it’s limited by
the area of the processor’s die that can be devoted to cache). Level L2 cache is a compromise. It is faster than
DRAM and slower than L1 cache. L2 sits between L1 and DRAM. In principle, you can have more levels, and
systems with L3 cache are not uncommon. When a memory access takes place, the L1 cache is searched first, then
the L2 cache, then the L3 cache…, then main store, then the hard drive (in that order).
