Reducing leakage in power-saving capable caches for embedded systems by using a filter cache
Roberto Giorgi, P. Bennati · 2007
Leakage power in data cache memories represents a sizable fraction of total power consumption, and many techniques have been proposed to reduce it. As a matter of fact, during a fixed period of time, only a small subset of cache lines is used. Previous techniques put unused lines, for example, to drowsy state or switch them off completely (cache decay) in order to save power.
