Abstract
There is provided an apparatus, a method, and a storage medium. The apparatus comprises one or more requestor devices to issue transaction requests, and one or more target devices to service those requests. The requestor devices and the target devices are configured to fulfil the requests according to a request ordering protocol specifying an ordered write observation behaviour in which, for each write transaction in a group of ordered write transactions, at least a deferred portion of the write transaction is deferred until all data specified in the group of ordered write transactions preceding the write transaction are observable. When implementing the request ordering protocol, the target devices are responsive to control information taking a first value to dynamically enable the ordered write observation behaviour, and the one or more target devices are responsive to the control information taking a second value to dynamically disable the ordered write observation behaviour.
