Abstract
Data processing apparatus comprises one or more transaction issuing devices configured to issue data processing transactions to be handled by a downstream device and to receive a completion acknowledgement in respect of each completed transaction; each transaction issuing device having associated transaction regulator circuitry configured to allow that transaction issuing device to issue transactions subject to a limit on a maximum number of outstanding transactions, an outstanding transaction being a transaction which has been issued but for which a completion acknowledgement has not yet been received; in which the downstream device is configured to issue an indication to a transaction issuing device, to authorize a change by the transaction regulator circuitry of the limit applicable to outstanding transactions by that transaction issuing device.
