US Patent 11288226 Methods and systems for address based transaction filters for on-chip communications fabrics

A configurable transaction filtering and logging circuit for on-chip communications within a semiconductor chip can store filter patterns. The filter patterns can include an address range filter pattern. The circuit can monitor transactions carried by an on-chip connection fabric. The transactions can be configured to transfer data between a first core circuit and a second core circuit that are also implemented on the semiconductor chip. The circuit can execute one of a set of actions in response to detecting a transaction that matches one of the filter patterns. One of the actions can be logging the transaction to a transaction log buffer in response to detecting that the transaction matches one of the filter patterns.
