Address assignment to transaction for serialization |
摘要 |
The assignment of an address to a transaction for serialization purposes is disclosed. A simulated address is assigned to a transaction of a first type. The simulated address may be determined by selecting a mask based on one or more bits of a command type attribute of the transaction, and performing a logical OR operation on the highest bits of the mask with a number of bits determined by concatenating various bits of various attributes of the transaction. The lowest bits of the resulting simulated address can be incremented for each transaction assigned a simulated address having the same highest bits. The transaction is serialized relative to other transactions of the first type, such as I/O-related transactions, utilizing a serialization approach for transactions of a second type. The serialization approach may be an existing approach already used to serialize transactions of the second type, such as coherent transactions.
