Abstract:
Approaches for communicating data from a source device to a target device. In one approach, a communicated data value is segmented into a plurality of data chunks at the source device. A sequence of interrupt transactions is transmitted from the source device to a system bus. The transmitting of each interrupt transaction in the sequence includes transmitting a target identifier on an address bus of the system bus, and the target identifier of each interrupt transaction in the sequence includes a respective one of the data chunks. The sequence of interrupt transactions from the system bus is received at the target device. The communicated data value is reassembled at the target device from the data chunks in the target identifier of the interrupt transactions in the sequence.
