Abstract
An apparatus has a monitoring data store for storing monitoring data indicating regions of a memory address space to be monitored for changes, which can include at least two non-contiguous regions. Processing circuitry updates the monitoring data in response to an update monitor instruction. Monitoring circuitry monitors accesses to the memory system and provides a notification to the processing circuitry when data associated with one of the monitored regions has changed. This improves performance and energy efficiency by reducing the overhead of polling changes to multiple regions.
