Estimating the term…
An apparatus and method for efficiently managing power consumption among multiple, replicated functional blocks of an integrated circuit. An integrated circuit includes multiple, replicated functional blocks that use separate power domains. Data of a given type is stored in an interleaved manner among the multiple functional blocks. When control circuitry detects a low-performance mode, commands are sent to the multiple functional blocks specifying storing data of the given type in a contiguous manner in one or more of the caches of the multiple functional blocks and the memories connected to the multiple functional blocks. Following, the control circuitry transitions the memories to a sleep state and transitions all but one of the functional blocks to the sleep state. The functional blocks rotate amongst themselves with a single functional block being in the active state and servicing requests based on which data of the given type is targeted by the requests.
