Abstract:
A plurality of new snoop transaction types are described. Some include address information in the requests, and others include cache entry information in the requests. Some responses include tag address information, and some do not. Some provide tag address content on the data bus lines during the data portion of the transaction. These new snoop transaction types are very helpful during debug of a data processing system.
