Abstract
A slave device on a data bus has a register that stores a non-queued split master vector containing bits identifying whether a transaction with corresponding master devices have been split. An input gate is responsive to the status of the slave device and to receipt of a command from a master device when the slave device status is busy to set a bit in the non-queued split master vector identifying that the transaction with the corresponding master device is split. An output gate is responsive to a not busy status of the slave device to output the non-queued split master vector to the arbiter to re-arbitrate use of the data bus among the previously-split non-queued master devices.
