Document Type and Number:
Japanese Patent JP6234484
Kind Code:
B2
Abstract:
Embodiments relate to a method and computer program product for prefetching data on a chip having at least one scout core and a parent core. The method includes saving a prefetch code start address by the parent core. The prefetch code start address indicates where a prefetch code is stored. The prefetch code is specifically configured for monitoring the parent core based on a specific application being executed by the parent core. The method includes sending a broadcast interrupt signal by the parent core to the at least one scout core. The broadcast interrupt signal being sent based on the prefetch code start address being saved. The method includes monitoring the parent core by the prefetch code executed by at least one scout core. The scout core executes the prefetch code based on receiving the broadcast interrupt signal.
