Abstract
An apparatus comprises an instruction decoderand processing circuitry. Monitoring circuitrymonitors one or more events indicative of a potential update to data associated with any of a monitored set of addresses, and makes accessible to software executing on the processing circuitrya monitoring reporting indication indicative of whether any events has occurred for at least one of the monitored set of addresses. In response to decoding of an exclusive status setting instruction specifying a given address, the processing circuitrysets an exclusive status associated with the given address. The exclusive status is cleared in response to detecting an event indicative of a conflicting memory access to the given address. In response to decoding of a monitor exclusive instruction, the processing circuitry: determines whether the exclusive status is associated with a target address, and if so allocates the target address to be one of the monitored set of addresses.
