Partition Identifier Remapping Circuitry for Memory Resource Isolation

The patent introduces partition identifier remapping circuitry as an intermediary layer between software execution environments and cache partitions. This remapping circuitry translates partition identifiers dynamically, enabling a software execution environment to access multiple cache partitions while maintaining performance isolation. The intermediary resolves the contradiction by decoupling the logical partition assignment from physical cache allocation, allowing flexible multi-partition access without compromising isolation guarantees.

The patent implements dynamic partition identifier remapping that allows cache partition assignments to change based on runtime conditions. The remapping circuitry can dynamically adjust which cache partitions are assigned to which software execution environments, enabling efficient resource utilization while maintaining performance isolation. This dynamic approach resolves the contradiction by allowing the system to adapt partition assignments to current workload demands rather than being constrained by static assignments.

The patent employs partition identifier remapping circuitry that performs partition assignment decisions in advance or at cache line allocation time rather than at access time. By pre-establishing partition mappings and caching these mappings, the system achieves dynamic resource utilization without incurring latency penalties during actual cache accesses. This preliminary action resolves the contradiction by separating the dynamic decision-making process from the time-critical cache access path.
