Abstract
We report methods, integrated circuit devices, and fabrication processes relating to power management transitions of multiple compute units sharing a cache. One method includes indicating that a first compute unit of a plurality of compute units of an integrated circuit device is attempting to enter a low power state, determining if the first compute unit is the only compute unit of the plurality in a normal power state, and in response to determining the first compute unit is the only compute unit in the normal power state: saving a state of a shared cache unit of the integrated circuit device, flushing at least a portion of a cache of the shared cache unit, repeating the flushing until either a second compute unit exits the low power state or the cache is completely flushed, and permitting the first compute unit to enter the low power state.
