For example, a processor might fail when a particular instruction is in a specific pipeline stage at the same time that a data FIFO is full and a cache miss occurs and a specific interrupt arrives. The large data set with low locality of reference results in high data cache miss rates and low (less than 30%) effective utilization of a single-threaded processor. The system uses adaptive cache algorithms that help to decrease the cache miss rate, all of which ultimately require statistical feedback, such as most frequently-accessed documents, most frequently-requested search terms, etc. |
