TRANSACTION RESPONSE MODIFICATION WITHIN INTERCONNECT CIRCUITRY

摘要

Interconnect circuitry 10 for connecting transaction masters 4, 6, 8 to transaction slaves 12, 14 includes response modification circuitry 18. The response modification circuitry includes shortlist buffer circuitry 28 storing identification for modification target transaction responses. The response modification circuitry 18 uses this identification data to identify among a stream of transaction responses in transit a modification target transaction response. The response modification circuitry 18 then serves to form a modified transaction response to be sent in place of the modification target transaction response to the transaction master 4, 6, 8.

1. An apparatus comprising:
response modification circuitry to:
store identification data for modification target transaction responses in a shortlist buffer;identify, using the identification data stored in the shortlist buffer, a modification target transaction response in a stream of transaction responses in transit from a transaction slave to a transaction master; andmodify the modification target transaction response to form a modified transaction response to be sent to the transaction master.
