Most if not all contemporary processors use caches to hide memory latency. In order to maintain a high clock speed, chip designers often resort to L1 caches that have no associativity, i.e.: direct-mapped caches. Since most processors in the past were designed to run a variety of applications, these caches were also designed to perform well on a variety of applications. Currently, however, many processors are embedded into devices that perform a dedicated task. As a result, application specific optimizations have become much more interesting than in the past.
