Abstract
An apparatus comprises memory access circuitry to perform a tag-guarded memory access in response to a target address, the tag-guarded memory access comprising a guard-tag check of comparing an address tag associated with the target address with a guard tag stored in association with a block of one or more memory locations comprising an addressed location identified by the target address. The memory access circuitry is responsive to a sequence of received target addresses specifying a sequence of addressed locations to perform a non-tag-guarded memory access that does not perform the guard-tag check to a subset of the sequence of addressed locations.
