Abstract
Processing circuitry () performs data processing in response to instructions. Memory management circuitry () controls access to memory based on page table information capable of associating a given page of memory address space with a read-as-X property indicative that reads to an address in the given page of memory address space should be treated as returning a specified value X. In response to determining, for a read request issued to read a read target value for a read target block of memory address space, that at least part of the read target block corresponds to a page associated with the read-as-X property, the memory management circuitry () controls the specified value X to be returned to the processing circuitry () as at least part of the read target value. This enables large regions of memory address space to be treated as storing a specified value without needing to commit physical memory for those regions.
