Abstract
A processing system selectively enables and disables a result lookaside buffer (RLB) based on a hit rate tracked by a counter, thereby reducing power consumption for lookups at the result lookaside buffer during periods of low hit rates and improving the overall hit rate for the result lookaside buffer. A controller increments the counter in the event of a hit at the RLB and decrements the counter in the event of a miss at the RLB. If the value of the counter falls below a threshold value, the processing system temporarily disables the RLB for a programmable period of time. After the period of time, the processing system re-enables the RLB and resets the counter to an initial value.
