Method and apparatus for power reduction in a multi-threaded mode
Abstract:
A method and apparatus for reducing dynamic power consumption in a multi-thread content-addressable memory is described. The 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 an associated register of the plurality of registers in a fully-associative configuration, and a second comparator bank including a second plurality of comparators each coupled to an associated register of the plurality of registers in a fully-associative configuration. An input virtual address to each comparator bank maintains its previous value for when a corresponding thread is not selected.
