Abstract: According to one general aspect, an apparatus may include a first cache configured to store data. The apparatus may include a second cache configured to, in response to a fill request, supply the first cache with data, and an incoming fill signal. The apparatus may also include an execution circuit configured to, via a load request, retrieve data from the first cache. The first cache may be configured to: derive, from the incoming fill signal, address and timing information associated with the fill request, and based, at least partially, upon the address and timing information, schedule the load request to attempt to avoid a load-fill conflict.

Abstract: 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.
