Granule protection information (GPI) loading circuitry loads from a memory system at least one granule protection descriptor providing GPI indicating, for at least one granule of physical addresses, which physical address spaces is allowed access to the at least one granule. GPI compressing circuitry compresses the GPI to generate compressed GPI. A GPI cache to caches the compressed GPI. Filtering circuitry determines, on a hit in the GPI cache, whether the memory access request should be allowed to access the target physical address, based on whether the compressed GPI cached in the GPI cache for the target physical address indicates that the selected physical address space is allowed access to the target physical address. This allows more efficient caching of granule protection information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Granule protection information compression","description":"Address translation circuitry translates a target virtual address specified by a memory access request into a target physical address associated with a selected physical address space.
