ABSTRACT:
Systems and methods for data intervention for out-of-order castouts are disclosed. Embodiments provide for transmitting snoopable requests received from one or more requesting devices to one or more snoopable devices, which may include requesting devices. Each snoopable device receives snoopable requests and determines if it holds the requested data in modified state. If so then the data is castout and transferred directly to the requesting device without waiting for the data to be read from the slave that was the target of the request. The order of transfers is arbitrated to be consistent with an order of received requests.
