Cross dependency checking logic
Abstract:
Systems and methods for maintaining an order of transactions in the coherence point. The coherence point stores attributes associated with received transactions in an input request queue (IRQ). When a new transaction is received by the coherence point, the IRQ is searched for other entries with the same request address or the same victim address as the new transaction. If one or more matches are found, the new transaction entry points to the entry storing the most recently received transaction with the same address. The new transaction is stalled until the transaction it points to has been completed in the coherence point.
