Examples
During a cache miss, the CPU usually ejects some other entry in order to make room for the previously uncached data.
The SA-110 was designed to be used with slow (and therefore low-cost) memory and therefore the high set associativity allows a higher hit rate than competing designs, and the use of virtual addresses allows memory to be simultaneously cached and uncached.
The previously uncached data fetched from the backing store during miss handling is usually copied into the cache, ready for the next access.
Imagine a program scanning bytes in a 32bit address space, but being served by a 128bit off chip data bus; individual uncached byte accesses would only allow 1/16th of the total bandwidth to be used, and 80% of the data movement would be addresses.
