摘要： Dynamically predicting a Read-After-Write (RAW) hazard by employing a variable confidence score attributed to a RAW Resynchronization Predictor (RRP) for sampling the RRP at timing periods dynamically adjusted based on the confidence score to optimize prediction of the RAW hazard.

摘要： 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.
