US Patent 7613849 Integrated circuit and method for transaction abortion

An integrated circuit includes processing modules and an interconnect device for coupling the processing modules and for enabling a device-level communication based on transactions between the processing modules. A first processing module issues a transaction towards a second processing module. The integrated circuit further includes a transaction abortion unit for aborting the transaction issued from the first module by receiving an abort request issued by the first module, by initiating a discard of the transaction to be aborted, and by issuing a response indicating the success/failure of the requested transaction abortion.
