Abstract:
1. Apparatus for identifying master devices whose transactions with a slave device have been split by the slave device in a data bus system for transferring data between the slave device and respective ones of a plurality of master devices, the apparatus comprising: a register for storing a split master vector identifying those master devices of the plurality of master devices whose transactions have been split by the slave device, the split master vector having at least as many bits as the number of master devices on the bus system; an input vector generator generating an input vector having at least as many as the number of master devices on the bus system, the input vector generator being responsive to a command from one of the plurality of master devices for generating an input vector having a bit corresponding to the one master device indicative of a split transaction, and a input gate responsive to a busy status of the slave device to combine the input vector with the split master vector.
