Prior to a point of physical aliasing (PoPA), a pre-PoPA memory system component 24, 8 treats aliasing PAs from different PASs which actually correspond to the same memory system resource as if they correspond to different memory system resources. A post-PoPA memory system component 6 treats the aliasing PAs as referring to the same memory system resource. When the target PA and target PAS of a read-if-hit-pre-PoPA request hit in a pre-PoPA cache 24, a data response is returned to the requester circuitry 4. If the read-if-hit-pre-PoPA request misses in the pre-PoPA cache 24, a no-data response is returned. The read-if-hit-pre-PoPA request is safe to issue speculatively while waiting for security checks to be performed, improving performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Read-if-hit-pre-PoPA request","description":"Requester circuitry 4 issues an access request specifying a target physical address (PA) and a target physical address space (PAS) identifier identifying a target PAS.
