Abstract
A method and apparatus for reducing dynamic power consumption in a multi-thread content-addressable memory (CAM) is described. The disclosed apparatus includes a first input configured to receive a first virtual address corresponding to a first thread, a second input configured to receive a second virtual address corresponding to a second thread, a register bank including a plurality of registers each configured to store a binary word mapped to one of a plurality of physical addresses, a first comparator bank including a first plurality of comparators each coupled to one of the plurality of registers in a fully-associative configuration and configured to determine whether a first match is present, and a second comparator bank including a second plurality of comparators each coupled to one of the plurality of registers in a fully-associative configuration and configured to determine whether a second match is present.
