Reduced power load/store queue searching by comparing subsets of address bits and enabling second subset comparison based on first subset comparison result |
摘要 |
A comparison circuit can reduce the amount of power consumed when searching a load queue or a store queue of a microprocessor. Some embodiments of the comparison circuit use a comparison unit that performs an initial comparison of addresses using a subset of the address bits. If the initial comparison results in a match, a second comparison unit can be enabled to compare another subset of the address bits.
